A B2 variable star lies at the heart of this dusty region of our galaxy. The star is not hot enough to produce the UV light needed to ionize hydrogen and give this nebula a reddish/pinkish glow. Instead, shorter wavelengths get strongly scattered by the dust, giving it the classic blue hues of a reflection nebula. The Iris Nebula lies in the constellation Cepheus, which is most easily seen in summer and early autumn from the Northern Hemisphere. It doesn't reveal much when observed visually through a telescope, but it sure does photograph well.

I had a little look round the car, it seems in fine condition. They are at the lowest price they're ever likely to be, so deprecation free motoring apart from any mechanical maladies that might occur. I'd imagine the common head gasket problems have been fixed with the upgrades that are available. Checking the history, the front and rear subframes will need attention sometime soon, I believe that's not unusual.
Comet 2017 E4 (Lovejoy) had a short "lifetime" after its discovery less than 7 weeks ago through Terry Lovejoy. Now the nucleus is desintegrated.

Description:
These are without a doubt two of the most popular targets for amateur astronomers with modest telescopes. Unfortunately for northern hemisphere observers, they are located far south in the constellation Sagittarius, so they are very low in the sky, especially for us in Canada.
M20, the Trifid Nebula (left of centre) is a combination blue reflection nebula and red emission nebula. For more information, click here:

The Crab Nebula, also known as Messier 1 or NGC 1952, is a famous astronomical object located in the constellation of Taurus. It is a supernova remnant, resulting from a massive stellar explosion that was observed by Chinese astronomers in the year 1054. The nebula is approximately 6,500 light-years away from Earth and spans about 10 light-years in diameter.
At the heart of the Crab Nebula lies a pulsar, which is a rapidly rotating neutron star. This pulsar, also known as the Crab Pulsar, is only about 6 miles in diameter, has a mass greater than the Sun and spins 30 times per second. Observations indicate that the Crab Nebula is expanding at a rate of 1,500 km per second since its explosion over 900 years ago.

This incredibly detailed image of the interacting triplet M81, M82, and NGC 3077 was created from more than 216 hours of exposure across three continents — Europe, USA, and Oceania. We combined 4019 subframes and 12993 minutes of exposure to reveal faint details previously masked by lower amounts of data. The high exposure time also allowed us to sharpen fine features, giving the image more contrast and revealing more fine structures.
On the top of the image lies NGC 3077, a small starburst dwarf galaxy with a starforming core. Below lies M81, a grand design spiral about 12 million light years away. To the right is M82, a starburst galaxy with a huge superwind triggered by interaction with M81 and NGC 3077. All around the image is the galactic cirrus, dust lit by the glow of the milky way. I highly recommend looking at the image with HI emission overlaid, which displays what of the background is neutral gas from the interactions and what is dust from the milky way.

I started exposing this image at 11:05 PM last night and finished at 2:46 AM this morning. Even though that was about 3 hours and 40 minutes there were a few dropped frames and processing time which reduced actually exposure time to 2 hours divided into 10 second subframes. Below is a screenshot depicting a step in post-processing.
The BMW R nineT is a standard motorcycle made by BMW Motorrad since 2014. It is a retro styled roadster marketed by BMW to custom builders and enthusiasts as a "blank canvas for customizing".
The BMW R nineT has several design elements configured to allow the bike to be easily modified, such as separate engine and chassis wiring harnesses and minimal bolts attaching the rear subframe, tail lights, and headlight.
The R nineT version of the bike has upside-down (USD) telescopic forks rather than BMW's usual Telelever front suspension. The other versions have conventional telescopic forks.
All variations have an air/oil-cooled oilhead flat twin (or boxer) 1,170 cc (71 cu in) engine, which has the inlet manifold at the rear of the cylinders and the exhaust at the front. The oilhead is arguably[by whom?] more suitable for customization as it has a more conventional appearance than the new water-cooled engine.
The R nineT Scrambler knows no conventions: rough, unadapted, individual. Its handling is balanced and unique. With the boxer, you can ride around with your head held high, it is available for every spontaneity. And the typical Scrambler look together with the relaxed seating position makes a lot of difference – and above all is a lot of fun. Design your R nineT Scrambler so that it fits perfectly into your life. No matter what the others say. Just typical Soulfuel.
Turn on the power: With the air/oil-cooled boxer of the Scrambler, you can do this in a playful way. We have optimised its power and torque curve and noticeably increased it in the 4,000 to 6,000 rpm range. This way, you have the power exactly where you need it and can remain powerful and completely relaxed out on the road. The peak torque remains at 116 Nm at 6,000 rpm. And of course the boxer complies with the Euro 5 standard.

Description:
This large, pretty and bright open cluster of stars, at the lower right in this view, happens to lie in our line of sight in front of one of the brighter, star-dense arms of our Milky Way galaxy. It is a favourite observational target of northern hemisphere astronomers on summer evenings. More than 30,000 stars can be seen in this photo.
From Wikipedia:
"The Wild Duck Cluster is one of the richest and most compact of the known open clusters, containing about 2900 stars. Its age has been estimated to about 250 million years. Its name derives from the brighter stars forming a triangle which could resemble a flying flock of ducks (or, from other angles, one swimming duck)."

Alfa Romeo 4C TBi SA (2013-20) Engine 1742cc S4 Turbo 237bhp
Registration Number S 2 HWM (Cherished number, now transferred to a BMW M2)
ALFA ROMEO ALBUM
www.flickr.com/photos/45676495@N05/sets/72157623759785842...
The 4C concept was debuted at the 2011 Geneva motor Show. Designed as a small lightweight, two seater mid engine rear wheel drive sports car. Slightly smaller than the Mito.
Designed by Lorenzo Ramaciotti at Alfa Romeo Centro Stile, using a carbon fibre tub, front rear crash box, and hybrid rear frame composed primarily of aluminium with a weight of around 850kg. The 4C has a high quadrilateral suspension at the front and MacPherson struts in the rear.
Powered by an new all aluminium 1750cc S4 turbo petrol engine of 230bhp with a capacity to produce 300bhp. The engine will probably be used in the new Guilia. The 4C is equipped with six speed Alfa TCT Dual Dry Clutch Transmission, and can be operated via gearshift paddles on steering wheel. It also has an Alfa DNA dynamic control selector which controls the behaviour of engine, brakes, steering, throttle response, suspension and gearbox
The production car was unveiled at the 2013 Geneva Motor
Show followed by the Essen Classica , the Goodwood Festival of Speed and the 2013 Frankfurt Autoshow, Production of 4C began May 2013 at Maserati's plant in Modena, with an expected production of up to 2500 units per year, with an upper limit of 3500 units per year, depending on the quantity of carbon fibre chassis that can be built by the supplier Adler Plastic
The car was designed by Centro Stile Alfa Romeo (Style Centre) and developed by Alfa Romeo. The chassis is composed of a central carbon fibre tub, with aluminium subframes front and rear. The carbon fibre tub is produced by TTA (Tecno Tessile Adler) in Airola, The entire carbon-fibre monocoque chassis (tub) of the car weighs a mere 143 lb (65 kg). Front and rear aluminium subframes combine with the tub, roof reinforcements and engine mounting to comprise the 4C chassis giving the vehicle a total chassis weight of 236 lb (107 kg) and a total vehicle curb weight of just 2,465 lb
The production 4C uses a new all-aluminium 1.75 L (1,742 cc) inline 4 cylinder turbocharged engine producing 240 bhp with a combined fuel consumption of 42 mpg a 0-62mph time of 4.5 seconds and a top speed of 160mph
The 4C Launch Edition was a limited and numbered edition, unveiled at the vehicle's launch at the 2013 Geneva Motor Show. The vehicle came in a choice of four paint colours (Rosso Alfa, Rosso Competizione tri-coat, Madreperla White tri-coat or Carrara White matt). 400 examples were reserved for Europe, Africa and the Middle East, 500 for North America and 100 for the rest of the world (88 delivered to Australia—in Rosso Alfa and Madreperla White only). Distinguishing features of the Launch Edition were carbon fibre trim (including headlight housings, spoiler and door mirror caps), rear aluminium extractor with dark finishing, Bi-LED headlights, dark painted 18-inch front and 19-inch rear alloy wheels, additional air intakes on the front fascia, red brake calipers, racing exhaust system, BMC air cleaner, specific calibration for shock absorbers and rear anti-roll bar, leather/fabric sports seats with parts in Alcantara and a numbered plaque. Alfa Red coloured cars got matching red stitching on the steering wheel, handbrake, mats, handles and sports seats
In Europe the vehicle went on sale for 60,000 euros including VAT
The North American bound versions debuted at the 2014 New York Motorshow differing from their European siblings, with new head lights similar to those seen before in the 4C Spider version.. The cars also require extra bracing and strengthening required to meet U.S. crash regulations (including aluminium inserts in the carbon fibre chassis), resulting in 100 kilograms (220 lb) of weight increase.

Soul with a Capital S - www.youtube.com/watch?v=OSCz31lcSxI
The first clear nights after the rainy season and I needed to test some new gear and combos and that was my excuse for picking some easy targets. This was taken with a Canon 400mm f5.6L lens on a QHY183C colour camera connected via an Astromechanics EF focus adapter which enabled Sequence Generator Pro's autofocus routine to work with the lens. The image is an integration of nearly 10 hours total exposure (199 x 180 second subframes). The mount was a Skywatcher AZ-EQ5. Image capture was managed via SGP and PHD2 and all post-processing was carried out in PixInsight. As usual, I was defeated by Alnitak.
Observed from Prachinburi, Thailand.

Description:
This faint and visually very elusive nebula can be photographed to advantage only in a good dark sky.
Known as the "California Nebula" because of its shape, this glowing cloud of red hydrogen gas is quite large; about five times as long as, and a little wider than, the Moon appears in our sky. The nebula is located 1,000 - 2,000 light years from our solar system, and is about 100 light years from end to end. Radiation from the nearby blue-white star Xi Persei (the brightest star in the frame, below the nebula) causes the nebula to fluoresce.
The California Nebula was discovered by famed American astronomer E.E. Barnard in 1884-5, just in time to be added to Dreyer's New General Catalog (NGC).

Taken with the C14 and SBIG STXL-6303 at Cerritos College. The moon was still below the horizon, and the sky was cloudless enough for me to do guided shots. There's always moist air to the south from campus, though, and the limiting magnitude was 17.2 for this image. 16 30 s subframes were stacked to create this. An Antlia L filter was used. The position of the supernova is indicated with white line segments.

ASTAP gives a CV magnitude of 11.8
This was essentially maximum brightness for this supernova.
I realize now that I was not setting apertures properly in ASTAP, and all of my previous magnitude estimates are likely too faint.

Description:
One of the best known star patterns in the sky - but one that is visible only from the northern hemisphere south of latitude 25° or from the southern hemisphere - is the Southern Cross, which is formed by three very bright stars and one fainter star in the constellation Crux (The Cross).
Nearby (to the left of centre in this view) is the dark foreground nebula called the "Coal Sack".
This part of the sky is strewn with numerous open star clusters.
This is the telescope and mount that I used for my astrophotography on this trip:

This two-frame assemblage shows how the appearance of the Moon changes in one day (well, in this case 25 hours), as the terminator (the dividing line between day and night) moves from right to left across the visible face of the Moon. On average, the terminator moves across the Moon's face about 12.7° per 24 hours, as the Moon orbits planet Earth once per month.
In the right frame, the Moon is 96.2% illuminated by the Sun; in the left frame, the illuminated portion has decreased to 90.6%.

Located just south of the end star of the Big Dipper in the constellation Ursa Major (The Great Bear) (but actually across the border in the constellation Canes Venatici - The Hunting Dogs) the Whirlpool galaxy is a favourite target of amateur astronomers, especially in the northern hemisphere spring and early summer.
M51, which has a black hole at its core, is about 35% of the size and mass of our own Milky Way galaxy. It was the first galaxy to be identified as spiral in structure. The two portions of this galaxy interact with each other; the smaller satellite portion is named NGC 5195. The distance to this galaxy is still quite uncertain; estimates are between 15 and 35 million light years. By contrast, the great Andromeda Galaxy lies a mere 3 million light years from us.

Description:
NGC 2602 is a bright open cluster of about 74 stars in the constellation Carina that is referred to as the "Southern Pleiades". The cluster, which can easily be seen with the unaided eye, was discovered by Abbe Lacaille in 1751 from South Africa. It is a very close star cluster, lying only about 547 light years from our solar system, as compared with the even closer (444 light years) Pleiades (also call M45).
NGC 2602 is the third brightest open cluster in the sky, after the Pleiades and the nearby Hyades, both of which are in the northern constellation Taurus (The Bull).
Nearby (near the top and just left of centre in this image) lies the fainter Melotte 101 (also designated Collinder 227), an 8th magnitude cluster of some 70 stars that lies a staggering 6,500 light years from us.

Photographed from mid-town Toronto, Canada, at 18.43 EST (Moon altitude: 54° | Sun 7.6° below the horizon)
* Temperature 5° C.
Although this evening was very clear, there was a persistent gusty wind from the west, which made it difficult to keep the telescope steady during the ten subframes that make up this image.
Here the Moon, gliding through the constellation Gemini (The Twins) was 78.7% sunlit, on its way to its full phase in the early evening of March 1 (four days from now).
Although it is subtle, some colour can be seen on the lunar disk, particularly in the Moon's so-called maria ("seas"), which of course are lava plains and not water.

This is the Milky Way from Mesa Verde National Park in Colorado. There’s tremendous detail in this image! I may annotate it later. That’s Jupiter there on the left, with the constellation of Sagittarius just to the lower right – it looks like a teapot. The upper left area is the Scutum star cloud. On the lower right is the “prancing horse”, a dark nebula that obscures the background stars.

Sub-framing is a type of compositional photography technique wherein one or more photo elements are framed by another element. It's a good way to add interest to the photo, lead the viewer's eye towards the middle of the sub-frame, and emphasize a subject.
I know neither the bride nor the groom but all have accepted me as a part of the event. I could have easily join the celebration!
This is a wide-field shot of the Heart Nebula I took last night using a QHY23M & 50mm F/1.8(at F/2.8) camera lens w Ha filter.
I dont have any kind of filter holder or wheel, but as luck would have it, the Optolong 2" Ha filter lays inside the indention of the lens.(Just have to be careful slewing the scope )
I combined 18- 5 minute subframes
The image covers 13.3x10.7 degrees of the sky.

Located just south of the end star of the Big Dipper in the constellation Ursa Major (The Great Bear) (but actually across the border in the constellation Canes Venatici - The Hunting Dogs) the Whirlpool galaxy is a favourite target of amateur astronomers, especially in the northern hemisphere spring and early summer.
M51, which has a black hole at its core, is about 35% of the size and mass of our own Milky Way galaxy. It was the first galaxy to be identified as spiral in structure. The two portions of this galaxy interact with each other; the smaller satellite portion is named NGC 5195. The distance to this galaxy is still quite uncertain; estimates are between 15 and 35 million light years. By contrast, the great Andromeda Galaxy lies a mere 3 million light years from us.

Maserati Khamsin (1973-82) Engine 4930cc V8 QOC Production 435
Registration Number WWL 637 T (Oxford)

Designed by Marcello Gandini at Bertone the Maserati Khamsin (Tipo AM120) is a grand tourer. Following Maserati's tradition it was named after a wind: the Khamsin, a hot, violent gust blowing in the Egyptian desert for fifty days a year.
The Khamsin was introduced on the Bertone stand at the November 1972 Turin Auto Show as a concept car, designed by Marcello Gandini, it was Bertone's first work for Maserati. In March 1973, the production model was shown at the Paris Motor Show. Regular production of the vehicle started only a year later, in 1974.The Khamsin was developed under Citroën's ownership of Maserati a front-engined grand tourer on the as a contrast to the rear engined Bora.
The Khamsin's body is prominently wedge-shaped, with a fastback roofline and kammback rear end. The tail is characterized by a full-width glass rear panel, carrying inset - floating lights. Cosmetic triangular vented panels are inlaid in the C-pillar, with the right-hand one hiding the fuel filler cap. Another distinguishing feature is the bonnet, pierced by asymmetrical vents. The Khamsin used an all-steel monocoque construction, with a rear Silentbloc-bushing insulated tubular subframe supporting the rear suspension and differential. Suspension was double wishbones all around. Apart from the adoption of Bosch electronic ignition, Maserati's 4.9 L (4,930 cc) DOHC, 16-valve V8 engine was carried over from the Ghibli SS and delivered 240 kW (330 PS; 320 hp). Maserati claimed a 270 km/h (170 mph) top speed for the European-specification model. In 1977 a mild facelift added three horizontal slats on the Khamsin's nose to aid cooling. Inside, it brought a restyled dashboard and a new padded steering wheel.
Despite the many improvements over its predecessor, the Khamsin did not replicate its success, partly due to the ongoing fuel crisis that reduced demand for cars with large displacement engines. Production ended in 1982, with 435 vehicles made, 155 of which had been exported to the United States - barely a third of the Ghibli's production total of 1,295
