A waxing gibbous moon competes for nocturnal illumination along with stars, distant skyglow and the blinding LED signals on BNSF's Needles Subdivison between Daggett and Barstow, California. It's a busy night on the western end of the Transcon, as a westbound approaches in the distance while another waits to proceed.
It's nearly impossible to convey the overwhelming sense of vastness one experiences in the desert at night- even surrounded by the railroad, nearby highways and the distant light pollution of the sprawl leaking out of the cracks in the Los Angeles Basin's mountainous defenses, one feels intensely aware of the insignificance of one's own existence, and the unsettlingly peaceful feeling that brings.
The "Little Pinwheel" galaxy in Ursa Major.
I've been trying an experiment using narrowband for green and red (Oiii and Ha), but from now on I will abandon narrowband on the SCT. I can't seem to get enough signal overall even with longer integrations and narrowband targets seem to fit the low FL scopes better.

...another attempt at the 1st shot of the Milky Way - this time I manually removed the skyglow - before processing everything else !!!
The California Nebula in Perseus is an emission nebula five times the size of the full moon, about 1000 light years away. This shot is named for my sister on her birthday! I've wanted to capture it for a while, but waited until late in the season when it's low in the sky for a good view.
This is my first image with data from multiple nights stacked, Drizzle stacked 2 hours of 3 min exposures with 33' of exposure from the evening of March 19 at Bad Wolf Ranch, and 87 minutes form the evening of 2021-03-26 from Willow House in Terlingua.
RedCat 250/51mm telescope, Baader SkyGlow filter, and ZWO ASI 533MC camera cooled to -10. Processed in Pixinsight with GHS and RC Astro *Xterminator plugins. Final exposure and crop in PS.
ennesima elaborazione da frustrato :) alla disperata ricerca della flux (la cui visibilità varia a seconda del tasso alcolico del medesimo), il tempo non collabora purtroppo. Mi piace ed affascina il dettaglio sulle galassie ed il bilanciamento colori ma è uno scatto tutto da rifare con un cielo degno, sob!

Yet another frustrated and cropped stack :) in a desperate search of flux (whose visibility varies depending on the alcohol content in the body), unfortunately the weather does not cooperate. I like the detail on the galaxies and the color balance but i need to start all over again with a sky worthy, sob!

Another experiment to see how low I could go, this time with a 114mm newt. Once again I caught PGC 3807486 (18.55 mag galaxy), but it took longer subs and the result was even fainter than with the 6", so I may be reaching the limits of my aperture/skies.
In all fairness, it was also a somewhat better night with better transparency. Still, not a bad performance by the little newt that started life as an Orion Starblast, a scope that you can check out from some public libraries.

Here's the result of last nights marathon. I forgot my timelapse trigger so had to do these by hand with a stopwatch which made for a long night.
A sequence of exposures 10 mins apart starting at 11:40 BST. The basic exposure is 1/1000s, ƒ8, ISO 400. During totality the exposure was increased to 1 second so the Blood Moon was visible.
At the end of the sequence a bank of cloud came in so I had to stop just as the moon was coming out of the Umbra.
This is two sequences composited as my 18mm lens only covered about half the duration of the eclipse. I have toned the skyglow in the bottom right corner blue but the colour of the moon is straight out of camera.
The summer stars coming into view in the morning! This image was taken yesterday morning, March 11, 2014 in Carbon County, PA. This 60 second exposure shows Cygnus in the center, Vega on the top center and Altair on the right.

Springing forth from the peak of Pike Knob in West Virginia, one of the darkest places in the state, the center of our Milky Way galaxy hangs low on the horizon as the Sagittarius arm extends toward the dark river of molecular dust clouds known as the Great Rift, flanked by innumerable stars along the galactic plane extending to Cepheus and the terrestrial horizon in the direction of North Fork Mountain.
Surprisingly difficult to get any detail on that galaxy...

I initially ran this as a test of the guiding, but let it run to see if I could pick up very faint galaxies around Mizar. To my surprise, despite the moonlight, I did get PGC 3807486, an 18.5 mag galaxy. It isn't much above the noise floor, but for a 6" scope in the moonlight I'll take it as a success.

Twilight is light produced by sunlight scattering in the upper atmosphere, when the Sun is below the horizon, which illuminates the lower atmosphere and the Earth's surface. The word twilight can also refer to the periods of time when this illumination occurs.
The lower the Sun is beneath the horizon, the dimmer the twilight (other factors such as atmospheric conditions being equal). When the Sun reaches 18° below the horizon, the twilight's brightness is nearly zero, and evening twilight becomes nighttime. When the Sun again reaches 18° below the horizon, nighttime becomes morning twilight. Owing to its distinctive quality, primarily the absence of shadows and the appearance of objects silhouetted against the lit sky, twilight has long been popular with photographers and painters, who often refer to it as the blue hour, after the French expression l'heure bleue.
By analogy with evening twilight, the word twilight is also sometimes used metaphorically, to imply that something is losing strength and approaching its end. For example, very old people may be said to be "in the twilight of their lives". The collateral adjective for twilight is crepuscular, which may be used to describe the behavior of animals that are most active during this period.
Twilight is defined according to the solar elevation angle θs, which is the position of the geometric center of the Sun relative to the horizon. There are three established and widely accepted subcategories of twilight: civil twilight (nearest the horizon), nautical twilight, and astronomical twilight (farthest from the horizon).
Civil twilight is the time when the geometric center of the Sun is between the horizon and 6° below the horizon.
Civil twilight is the period when enough natural light remains that artificial light in towns and cities is not needed. In the United States' military, the initialisms BMCT (begin morning civil twilight, i.e., civil dawn) and EECT (end evening civil twilight, i.e., civil dusk) are used to refer to the start of morning civil twilight and the end of evening civil twilight, respectively. Civil dawn is preceded by morning nautical twilight and civil dusk is followed by evening nautical twilight.
Under clear weather conditions, civil twilight approximates the limit at which solar illumination suffices for the human eye to clearly distinguish terrestrial objects. Enough illumination renders artificial sources unnecessary for most outdoor activities. At civil dawn and at civil dusk sunlight clearly defines the horizon while the brightest stars and planets can appear. As observed from the Earth (see apparent magnitude), sky-gazers know Venus, the brightest planet, as the "morning star" or "evening star" because they can see it during civil twilight.
Lawmakers have enshrined the concept of civil twilight. Such statutes typically use a fixed period after sunset or before sunrise (most commonly 20–30 minutes), rather than how many degrees the Sun is below the horizon. Examples include when drivers of automobiles must turn on their headlights (called lighting-up time in the UK), when hunting is restricted, or when the crime of burglary is to be treated as nighttime burglary, which carries stiffer penalties in some jurisdictions.
The period may affect when extra equipment, such as anti-collision lights, is required for aircraft to operate. In the US, civil twilight for aviation is defined in Part 1.1 of the Federal Aviation Regulations (FARs) as the time listed in the American Air Almanac.
Nautical twilight is defined as when the geometric center of the Sun is between 12° and 6° below the horizon.
Before nautical dawn and after nautical dusk, sailors cannot navigate via the horizon at sea as they cannot clearly see the horizon. At nautical dawn and nautical dusk, the human eye finds it difficult, if not impossible, to discern traces of illumination near the sunset or sunrise point of the horizon (first light after nautical dawn but before civil dawn and nightfall after civil dusk but before nautical dusk).
Sailors can take reliable star sightings of well-known stars, during the stage of nautical twilight when they can distinguish a visible horizon for reference (i.e. after astronomic dawn or before astronomic dusk).
Under good atmospheric conditions with the absence of other illumination, during nautical twilight, the human eye may distinguish general outlines of ground objects but cannot participate in detailed outdoor operations.
Nautical twilight has military considerations as well. The initialisms BMNT (begin morning nautical twilight, i.e. nautical dawn) and EENT (end evening nautical twilight, i.e. nautical dusk) are used and considered when planning military operations. A military unit may treat BMNT and EENT with heightened security, e.g. by "standing to", in which everyone assumes a defensive position.
Astronomical twilight is defined as when the geometric center of the Sun is between 18° and 12° below the horizon.[3][4][2] During astronomical twilight, the sky is dark enough to permit astronomical observation of point sources of light such as stars, except in regions with more intense skyglow due to light pollution, moonlight, auroras, and other sources of light. Some critical observations, such as of faint diffuse items such as nebulae and galaxies, may require observation beyond the limit of astronomical twilight. Theoretically, the faintest stars detectable by the naked eye (those of approximately the sixth magnitude) will become visible in the evening at astronomical dusk, and become invisible at astronomical dawn.
Observers within about 48°34' of the Equator can view twilight twice each day on every date of the year between astronomical dawn, nautical dawn, or civil dawn, and sunrise as well as between sunset and civil dusk, nautical dusk, or astronomical dusk. This also occurs for most observers at higher latitudes on many dates throughout the year, except those around the summer solstice. However, at latitudes closer than 8°35' (between 81°25’ and 90°) to either Pole, the Sun cannot rise above the horizon nor sink more than 18° below it on the same day on any date, so this example of twilight cannot occur because the angular difference between solar noon and solar midnight is less than 17°10’.
Observers within 63°47'50" of the Equator can view twilight twice each day on every date between the month of the autumnal equinox and the month of vernal equinox between astronomical dawn, nautical dawn, or civil dawn, and sunrise as well as between sunset and civil dusk, nautical dusk, or astronomical dusk, i.e., from September 1 to March 31 of the following year in the Northern Hemisphere and from March 1 to September 30 in the Southern Hemisphere.
The nighttime/twilight boundary solar midnight's latitude varies depending on the certain month:
In the months of January or July, astronomical dawn to sunrise or sunset to astronomical dusk occurs at latitudes less than 48°54' North or South, because in the months of January or July the Sun's declination is less than 23°06' from the Equator;
In the months of February or August, astronomical dawn to sunrise or sunset to astronomical dusk occurs at latitudes less than 54°02' North or South, because in the months of February or August the Sun's declination is less than 17°58' from the Equator;
In the months of March or September before the equinoxes, astronomical dawn to sunrise or sunset to astronomical dusk occurs at latitudes less than 63°47' North or South, because in the months of March or September before the equinoxes the Sun's declination is less than 8°13' from the Equator;
During the equinoxes, astronomical dawn to sunrise or sunset to astronomical dusk occurs at latitudes less than 72°00' North or South, because during the equinoxes the Sun is crossing the Equator line;
In the months of March or September after the equinoxes, astronomical dawn to sunrise or sunset to astronomical dusk occurs at latitudes less than 67°45' North or South, because in the months of March or September after the equinoxes the Sun's declination is less than 4°15' from the Equator;
In the months of April or October, astronomical dawn to sunrise or sunset to astronomical dusk occurs at latitudes less than 57°09' North or South, because in the months of April or October the Sun's declination is less than 14°51' from the Equator;
In the months of May or November, astronomical dawn to sunrise or sunset to astronomical dusk occurs at latitudes less than 50°03' North or South, because in the months of May or November the Sun's declination is less than 21°57' from the Equator;
In the months of June or December, astronomical dawn to sunrise or sunset to astronomical dusk occurs at latitudes less than 48°34' North or South, because in the month of June the Sun crosses the Tropic of Cancer (about 23°26' North) and in the month of December the Sun crosses the Tropic of Capricorn (about 23°26' South).
At latitudes greater than about 48°34' North or South, on dates near the summer solstice (June 21 in the Northern Hemisphere or December 21 in the Southern Hemisphere), twilight can last from sunset to sunrise, since the Sun does not sink more than 18 degrees below the horizon, so complete darkness does not occur even at solar midnight. These latitudes include many densely populated regions of the Earth, including the entire United Kingdom and other countries in northern Europe and even parts of central Europe. This also occurs in the Southern Hemisphere, but occurs on December 21. This type of twilight also occurs between one day and the next at latitudes within the polar circles shortly before and shortly after the period of midnight sun. The summer solstice in the Northern Hemisphere is on June 21st, while the summer solstice in the Southern Hemisphere is on December 21st.
Civil twilight: between about 60°34' and 65°44' north or south. In the northern hemisphere, this includes the center of Alaska,Iceland, Finland, Sweden, Norway, Faroe Islands and Shetland. In the southern hemisphere this includes parts of the Southern Ocean and the northern tip of the Antarctic Peninsula. When civil twilight lasts all night, this is also referred as a white night.
Nautical twilight: between about 54°34' and 60°34' north or south. In the northern hemisphere this includes the center of Alaska, Russia, Canada, Estonia, Latvia, Scotland, Norway, Sweden,Finland, Lithuania, and Denmark. In the southern hemisphere this includes the southernmost point of South America, and Ushuaia in Argentina. When nautical twilight lasts all night, this is also referred as a white night.
Astronomical twilight: between about 48°34' and 54°34' north or south. In the northern hemisphere, this includes the center of Isle of Man, Aleutian Islands, United Kingdom, Belarus, Ireland, Netherlands, Poland, Germany, Belgium, Czech Republic, Bellingham, Washington, Orcas Island, Washington, Vancouver, British Columbia, Paris, France, Luxembourg, Guernsey, Ukraine, Slovakia and Hungary. In the southern hemisphere this includes the center of South Georgia and the South Sandwich Islands, Bouvet Island, Heard Island, Falkland Islands. It also includes El Calafate and Río Gallegos in Argentina, and Puerto Natales in Chile. When astronomical twilight lasts all night, this does not constitute a white night. This phenomenon is known as the grey nights, nights when it does not get dark enough for astronomers to do their observations of the deep sky.
In Arctic and Antarctic latitudes in wintertime, the polar night only rarely produces complete darkness for 24 hours each day. This can occur only at locations within about 5.5 degrees of latitude of the Pole, and there only on dates close to the winter solstice. At all other latitudes and dates, the polar night includes a daily period of twilight, when the Sun is not far below the horizon. Around winter solstice, when the solar declination changes slowly, complete darkness lasts several weeks at the Pole itself, e.g., from May 11 to July 31 at Amundsen–Scott South Pole Station. North Pole has the experience of this from November 13 to January 29.
Solar noon at civil twilight during a polar night: between about 67°24' and 72°34' north or south.
Solar noon at nautical twilight during a polar night: between about 72°34' and 78°34' north or south.
Solar noon at astronomical twilight during a polar night: between about 78°34' and 84°34' north or south.
Solar noon at night during a polar night: between approximately 84°34' and exactly 90° north or south.
At latitudes greater than 81°25' North or South, as the Sun's angular elevation difference is less than 18 degrees, twilight can last for the entire 24 hours. This occurs for one day at latitudes near 8°35’ from the Pole and extends up to several weeks the further toward the Pole one goes. This happens both near the North Pole and near the South Pole. The only permanent settlement to experience this condition is Alert, Nunavut, Canada, where it occurs from February 22–26, and again from October 15–19.
The duration of twilight depends on the latitude and the time of the year. The apparent travel of the Sun occurs at the rate of 15 degrees per hour (360° per day), but sunrise and sunset happen typically at oblique angles to the horizon and the actual duration of any twilight period will be a function of that angle, being longer for more oblique angles. This angle of the Sun's motion with respect to the horizon changes with latitude as well as the time of year (affecting the angle of the Earth's axis with respect to the Sun).
At Greenwich, England (51.5°N), the duration of civil twilight will vary from 33 minutes to 48 minutes, depending on the time of year. At the equator, civil twilight can last as little as 24 minutes. This is true because at low latitudes the Sun's apparent movement is perpendicular to the observer's horizon. But at the poles, civil twilight can be as long as 2–3 weeks. In the Arctic and Antarctic regions, twilight (if there is any) can last for several hours. There is no astronomical twilight at the poles near the winter solstice (for about 74 days at the North Pole and about 80 days at the South Pole). As one gets closer to the Arctic and Antarctic circles, the Sun's disk moves toward the observer's horizon at a lower angle. The observer's earthly location will pass through the various twilight zones less directly, taking more time.
Within the polar circles, twenty-four-hour daylight is encountered in summer, and in regions very close to the poles, twilight can last for weeks on the winter side of the equinoxes. Outside the polar circles, where the angular distance from the polar circle is less than the angle which defines twilight (see above), twilight can continue through local midnight near the summer solstice. The precise position of the polar circles, and the regions where twilight can continue through local midnight, varies slightly from year to year with Earth's axial tilt. The lowest latitudes at which the various twilights can continue through local midnight are approximately 60.561° (60°33′43″) for civil twilight, 54.561° (54°33′43″) for nautical twilight and 48.561° (48°33′43″) for astronomical twilight.
Winlaton Mill is a village in Tyne and Wear, North East England. It is not to be confused with Winlaton to the northwest which now comprises the southern part of Blaydon. The village is halfway between Gateshead to the northeast and Rowlands Gill to the southwest. Statistically Winlaton Mill is part of the ward of Winlaton and High Spen which contains part of Blaydon, High Spen and other outlying villages. The village is on the A694 which joins the A1 at Swalwell and contains the Red Kite Pub and Restaurant. Winlaton Mill is near the River Derwent which may suggest its name.
Tyne and Wear is a ceremonial county in North East England. It borders Northumberland to the north and County Durham to the south, and the largest settlement is the city of Newcastle upon Tyne.
The county is largely urbanised. It had a population of 1.14 million in 2021. After Newcastle (300,125) the largest settlements are the city of Sunderland (170,134), Gateshead (120,046), and South Shields (75,337). Nearly all of the county's settlements belong to either the Tyneside or Wearside conurbations, the latter of which also extends into County Durham. Tyne and Wear contains five metropolitan boroughs: Gateshead, Newcastle upon Tyne, Sunderland, North Tyneside and South Tyneside, and is covered by two combined authorities, North of Tyne and North East. The county was established in 1974 and was historically part of Northumberland and County Durham, with the River Tyne forming the border between the two.
The most notable geographic features of the county are the River Tyne and River Wear, after which it is named and along which its major settlements developed. The county is also notable for its coastline to the North Sea in the east, which is characterised by tall limestone cliffs and wide beaches.
In the late 600s and into the 700s Saint Bede lived as a monk at the monastery of St. Peter and of St. Paul writing histories of the Early Middle Ages including the Ecclesiastical History of the English People.
Roughly 150 years ago, in the village of Marsden in South Shields, Souter Lighthouse was built, the first electric structure of this type.
The Local Government Act 1888 constituted Newcastle upon Tyne, Gateshead and Sunderland as county boroughs (Newcastle had "county corporate" status as the "County and Town of Newcastle upon Tyne" since 1400). Tynemouth joined them in 1904. Between the county boroughs, various other settlements also formed part of the administrative counties of Durham and of Northumberland.
The need to reform local government on Tyneside was recognised by the government as early as 1935, when a Royal Commission to Investigate the Conditions of Local Government on Tyneside was appointed. The three commissioners were to examine the system of local government in the areas of local government north and south of the river Tyne from the sea to the boundary of the Rural District of Castle Ward and Hexham in the County of Northumberland and to the Western boundary of the County of Durham, to consider what changes, if any, should be made in the existing arrangements with a view to securing greater economy and efficiency, and to make recommendations.
The report of the Royal Commission, published in 1937, recommended the establishment of a Regional Council for Northumberland and Tyneside (to be called the "Northumberland Regional Council") to administer services that needed to be exercised over a wide area, with a second tier of smaller units for other local-government purposes. The second-tier units would form by amalgamating the various existing boroughs and districts. The county boroughs in the area would lose their status. Within this area, a single municipality would be formed covering the four county boroughs of Newcastle, Gateshead, Tynemouth, South Shields and other urban districts and boroughs.
A minority report proposed amalgamation of Newcastle, Gateshead, Wallsend, Jarrow, Felling, Gosforth, Hebburn and Newburn into a single "county borough of Newcastle-on-Tyneside". The 1937 proposals never came into operation: local authorities could not agree on a scheme and the legislation of the time did not allow central government to compel one.
Tyneside (excluding Sunderland) was a Special Review Area under the Local Government Act 1958. The Local Government Commission for England came back with a recommendation to create a new county of Tyneside based on the review area, divided into four separate boroughs. This was not implemented. The Redcliffe-Maud Report proposed a Tyneside unitary authority, again excluding Sunderland, which would have set up a separate East Durham unitary authority.
The White Paper that led to the Local Government Act 1972 proposed as "area 2" a metropolitan county including Newcastle and Sunderland, extending as far south down the coast as Seaham and Easington, and bordering "area 4" (which would become Tees Valley). The Bill as presented in November 1971 pruned back the southern edge of the area, and gave it the name "Tyneside". The name "Tyneside" proved controversial on Wearside, and a government amendment changed the name to "Tyne and Wear" at the request of Sunderland County Borough Council.
Tyne and Wear either has or closely borders two official Met Office stations, neither located in one of the major urban centres. The locations for those are in marine Tynemouth where Tyne meets the North Sea east of Newcastle and inland Durham in County Durham around 20 kilometres (12 mi) south-west of Sunderland. There are some clear differences between the stations temperature and precipitation patterns even though both have a cool-summer and mild-winter oceanic climate.
Tyne and Wear contains green belt interspersed throughout the county, mainly on the fringes of the Tyneside/Wearside conurbation. There is also an inter-urban line of belt helping to keep the districts of South Tyneside, Gateshead, and Sunderland separated. It was first drawn up from the 1950s. All the county's districts contain some portion of belt.
Although Tyne and Wear County Council was abolished in 1986, several joint bodies exist to run certain services on a county-wide basis. Most notable is the Tyne and Wear Passenger Transport Authority, which co-ordinates transport policy. Through its passenger transport executive, known as Nexus, it owns and operates the Tyne and Wear Metro light rail system, and the Shields ferry service and the Tyne Tunnel, linking communities on either side of the River Tyne. Also through Nexus, the authority subsidises socially necessary transport services (including taxis) and operates a concessionary fares scheme for the elderly and disabled. Nexus has been an executive body of the North East Joint Transport Committee since November 2018.
Other joint bodies include the Tyne and Wear Fire and Rescue Service and Tyne & Wear Archives & Museums, which was created from the merger of the Tyne and Wear Archives Service and Tyne and Wear Museums. These joint bodies are administered by representatives of all five of the constituent councils. In addition the Northumbria Police force covers Northumberland and Tyne and Wear.
There have been occasional calls for Tyne and Wear to be abolished and the traditional border between Northumberland and County Durham to be restored.
Tyne and Wear is divided into 12 Parliamentary constituencies. Historically, the area has been a Labour stronghold; South Shields is the only Parliamentary constituency that has never returned a Conservative Member of Parliament (MP) to the House of Commons since the Reform Act of 1832.
Newcastle and Sunderland are known for declaring their election results early on election night. Therefore, they frequently give the first indication of nationwide trends. An example of this was at the 2016 European Union referendum. Newcastle was the first large city to declare, and 50.6% of voters voted to Remain; this proportion was far lower than predicted by experts. Sunderland declared soon after and gave a 62% vote to Leave, much higher than expected. These two results were seen as an early sign that the United Kingdom had voted to Leave.
Offshore Group Newcastle make oil platforms. Sage Group, who produce accounting software, are based at Hazlerigg at the northern end of the Newcastle bypass. Northern Rock, which became a bank in 1997 and was taken over by Virgin Money in November 2011, and the Newcastle Building Society are based in Gosforth. The Gosforth-based bakery Greggs now has over 1,500 shops. The Balliol Business Park in Longbenton contains Procter & Gamble research and global business centres and a tax credits call centre for HMRC, and is the former home of Findus UK. The Government National Insurance Contributions Office in Longbenton, demolished and replaced in 2000, had a 1 mile (1.6 km) long corridor.
Be-Ro and the Go-Ahead Group bus company are in central Newcastle. Nestlé use the former Rowntrees chocolate factory on the east of the A1. BAE Systems Land & Armaments in Scotswood, formerly Vickers-Armstrongs, is the main producer of British Army tanks such as the Challenger 2. A Rolls-Royce apprentice training site is next door.[18] Siemens Energy Service Fossil make steam turbines at the CA Parsons Works in South Heaton. Sir Charles Parsons invented the steam turbine in 1884, and developed an important local company. Domestos, a product whose main ingredient is sodium hypochlorite, was originated in Newcastle in 1929 by William Handley, and was distributed from the area for many years.
Clarke Chapman is next to the A167 in Gateshead. The MetroCentre, the largest shopping centre in Europe, is in Dunston. Scottish & Newcastle was the largest UK-owned brewery until it was bought by Heineken and Carlsberg in April 2008, and produced Newcastle Brown Ale at the Newcastle Federation Brewery in Dunston until production moved to Tadcaster in September 2010. At Team Valley are De La Rue, with their largest banknote printing facility, and Myson Radiators, the second largest in the UK market. Petards make surveillance equipment including ANPR cameras, and its Joyce-Loebl division makes electronic warfare systems and countermeasure dispensing systems such as the AN/ALE-47. Sevcon, an international company formed from a part of Smith Electric, is a world leader in electric vehicle controls. AEI Cables and Komatsu UK construction equipment at Birtley.
J. Barbour & Sons make outdoor clothing in Simonside, Jarrow. SAFT Batteries make primary lithium batteries on the Tyne in South Shields. Bellway plc houses is in Seaton Burn in North Tyneside. Cobalt Business Park, the largest office park in the UK, is at Wallsend, on the former site of Atmel, and is the home of North Tyneside Council. Swan Hunter until 2006 made ships in Wallsend, and still designs ships. Soil Machine Dynamics in Wallsend on the Tyne makes Remotely operated underwater vehicles, and its Ultra Trencher 1 is the world's largest submersible robot.

Grundfos, the world's leading pump manufacturer, builds pumps in Sunderland. Calsonic Kansei UK, formerly Magna, make automotive instrument panels and car trim at the Pennywell Industrial Estate. Gestamp UK make automotive components. Smith Electric Vehicles originated in Washington. The LG Electronics microwave oven factory opened in 1989, closed in May 2004, and later became the site of the Tanfield Group. Goodyear Dunlop had their only UK car tyre factory next to the Tanfield site until its 2006 closure. BAE Systems Global Combat Systems moved to a new £75 million factory at the former Goodyear site in 2011, where they make large calibre ammunition for tanks and artillery.
The government's child benefit office is in Washington. Liebherr build cranes next to the Wear at Deptford. The outdoor clothing company Berghaus is in Castletown. Vaux Breweries, who owned Swallow Hotels, closed in 1999. ScS Sofas are on Borough Road.

The last deep-sky object for the night was also my favorite for the night. The reasonably bright face-on Spiral Galaxy NGC 3184 in the Great Bear is a delightful object with a prominent core and subtle knots in its spiral arms. When viewing NGC 3184 for the first time, one’s heart will jump since a magnitude 11 star shines just to the north of the core – a supernova mimic if I have ever seen one. However, the star belongs to our own Milky Way galaxy and just happens to be in the same line-of-sight as the galaxy.
There are two additional NGC numbers (3180 and 3181) which are Hydrogen II active star forming regions within this spiral galaxy. Normally, this would be beyond the reach of my refractor, but by switching out the Moon & Skyglow filter and replacing it with a Hydrogen-alpha 6nm filter while retaining the already connected light enhancement device, I could make out two slightly brighter knots within the two-armed spiral galaxy. If my research is sound, these are the two HII regions that have been assigned NGC numbers.
The common name for NGC 3184 is “The Little Pinwheel Galaxy”. It is well worth a visit.
A view of the summer Milky Way taken on the morning on April 10, 2014. For reference, I included an outline of Cygnus and the location of Vega and Altair, can you find the North America Nebula (NGC 7000)?

"The Horsehead Nebula (also known as Barnard 33 in emission nebula IC 434) is a dark nebula in the constellation Orion.[1] The nebula is located just to the south of the star Alnitak, which is farthest east on Orion's Belt, and is part of the much larger Orion Molecular Cloud Complex. The Horsehead Nebula is approximately 1500 light years from Earth. It is one of the most identifiable nebulae because of the shape of its swirling cloud of dark dust and gases, which is similar to that of a horse's head when viewed from Earth. " fonte wiki

This is a cross-section of the main part of M31, the Andromeda galaxy, with M32 top right and M110 lower left. Both M32 and M110 are satellite galaxies of M31.
The image was taken just two nights after the full Moon and combined with the skyglow and increasing mistiness in the atmosphere and then thin cloud made it a more challenging target than it would normally be.

Note the fainter irregular galaxy companion located here to the right and slightly below NGC1023's disk (designated as either PGC 10139 or NGC 1023A. I almost missed it thinking it was a processing error due to its lack of an obvious core.
