Description:
This view of the centre of our home galaxy - the Milky Way - lies in the familiar constellations Sagittarius (left side) and Scorpius (right side). This part of the cosmos is always very low in the sky as seen from the northern Hemisphere.
When I captured the ten subframes that comprise this image, the constellations Sagittarius and Scorpius were almost directly overhead. The dark sky of the Australian Outback makes for a dramatic, high-contrast view.
Here is the equipment used to make this image:

Description:
One of the showpieces of the northern hemisphere summer sky is this diffuse nebula of hydrogen gas, which can be seen in amateur telescopes quite low in the southern sky, just outside the band of the Milky Way.
Known as the "Omega Nebula" because of the similarity of its shape to the last letter in the Greek alphabet, M17 is a hotbed of star formation.
From Wikipedia: "The Omega Nebula is between 5,000 and 6,000 light-years from Earth and it spans some 15 light-years in diameter. The cloud of interstellar matter of which this nebula is a part is roughly 40 light-years in diameter and has a mass of 30,000 solar masses. The total mass of the Omega Nebula is an estimated 800 solar masses.
It is considered one of the brightest and most massive star-forming regions of our galaxy. ...
The open cluster NGC 6618 lies embedded in the nebulosity and causes the gases of the nebula to shine due to radiation from these hot, young stars."

Description:
As it revolves around the Sun in its stately 30-year orbit, the gas giant planet Saturn passes through each constellation of the zodiac in about two and half years. 2018 finds Saturn in the constellation Sagattarius (the Archer), set against the star clouds and nebulae that lie toward the centre of our Milky Way galaxy.
Saturn is the brightest object left of and below centre in this view. The massive red-pink Lagoon Nebula appears at lower right, with the smaller Trifid Nebula (with both blue and red components) above it. Many star clouds and tendrils of dark foreground gas can be seen throughout this region of the galaxy.
Right now Saturn shines at magnitude 0.0, and lies about 9 AU (astronomical units, the average distance between the Sun and Earth) from us. Light takes 1 hr 15 min to travel from Saturn to Earth. It is moving in retrograde motion (i.e., backwards, from east to west, or from left to right in this view), and will do so until mid-September, when it will come to a standstill and resume direct motion from west to east. At that time in September, Saturn will lie much closer to the Lagoon and Trifid nebulae.

This image was taken at the end of August 2019. With a Vixen Visac and a ZWO ASI 071 MC.
I didn't post it until today.
I still have some more images that I have not shared on my social networks and I hope to present them.

Watched live on YouTube in Garden Village, Burnaby, British Columbia, Canada
Won by Nickas Nielsen, Antonio Fuoco and Miguel Molina in the No. 50 car.
Ferrari AF Corse Hypercar
449P
The car's 2,992 cc (182.6 cu in) twin-turbocharged V6 engine architecture is shared with the Ferrari 296 and its Group GT3 counterpart, the 296 GT3. However, instead of being mounted to the subframe as in the road-going vehicle, the engine is a fully stressed member in the 499P, and has had various modifications to accommodate its new role as a stress-bearing member. The 499P has semi-permanent all-wheel drive, with an electric motor situated at the front axle, providing 200 kW (272 PS; 268 hp) above 190 km/h (118 mph) (as stipulated by the regulations), and is connected to a bespoke 900 V battery pack, with the ability to be recharged by Ferrari's own Energy Recovery System (ERS)
This is my project for October 2017: Helix Nebula (NGC 7293) or: "The Eye of God". This is a preliminary version of this ongoing project, this one only without narrow band filters. 24 h total exposure time (180 sec for each subframe). Only data of the RGB camera with a L-pro filter.
ATIK 490 color on Hyperstar 14" /F1.9. ASA DDM85 mount with pointing file guiding. Six nights of capturing in October 2017. Later I will process the narrow band filter data (h-Alpha, OIII, SII and infrared) collected in parallel for another 24 hours. Tenerife 1180 meters above sea level.
M31 with M32 lower middle and M110 upper right. This image was taken in light polluted skies with a colour deep sky camera and is a stack of just 20x2minutes subframes. I was experimenting with its settings to see what would work effectively on this target without the usual problem of over-exposing the central area. Normally with deep sky CCD cameras I need two or three hours of data to get a similar result.

Description:
Although Scutum is the fifth smallest constellation in the sky, it contains many open star clusters, a globular star cluster, and many dark foreground gas clouds. Located in the heart of northern hemisphere summer Milky Way, Scutum also features a bright starcloud that is easily visible to the unaided eye, and is magnificent to observe in binoculars - as long as you are in a dark sky location well away from the light pollution of our cities!

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.
2024-04-27.222
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.
This is a close-up of relatively small but bright planetary nebula M57. It is a LRGB where the luminance subframes are all just 1 second each. I admit it was an unintentional error but it worked! I had actually set them for 3 seconds each but a technical problem that froze the camera before I could start recording meant that when I re-set I failed to notice it had reverted to 1 second per frame.

Description:
This large, pretty and bright open cluster of stars - which happens to lie in our line of sight in front of one of the bright and star-dense arms of our Milky Way galaxy - is a favourite observational target of northern hemisphere astronomers on summer evenings.
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)."

Description:
One of the brightest sections in our home galaxy, the Milky Way, appears in the small constellation Scutum (the Shield), which appears in the southern sky half way from the horizon to the zenith as seen from southern Canada and the northern United States.
In this area appear many foreground cold, dark nebulae, which obscure the light of the stars beyond. These dark regions were photographed and catalogued by the great American astronomer E. E. Barnard (1857 - 1923) (en.wikipedia.org/wiki/Edward_Emerson_Barnard), and bear the designation "B", numbered from 1 to 370.
Near the centre of this view is a favourite target of amateur astronomers with modest telescopes: M11, the "Wild Duck Cluster". This is a rich open cluster of stars that looks like a duck in flight. See en.wikipedia.org/wiki/Wild_Duck_Cluster for more information about M11.

Description:
The LMC is satellite galaxy of our own Milky Way that is part of the Local Group of galaxies, lies about 163,000 light years from us, and has a diameter of about 14,000 light years. Nearby is the smaller galaxy called the Small Magellanic Cloud (SMC).
To the unaided eye in a dark sky site the LMC is a large, faint glowing patch that appears detached from the band of the Milky Way.
From Wikipedia:
"Although both clouds have been easily visible for southern nighttime observers well back into prehistory, the first known written mention of the Large Magellanic Cloud was by the Persian astronomer `Abd al-Rahman al-Sufi Shirazi, (later known in Europe as "Azophi"), in his Book of Fixed Stars around 964 AD.
The next recorded observation was in 1503–4 by Amerigo Vespucci in a letter about his third voyage. In this letter he mentions "three Canopes [sic], two bright and one obscure"; "bright" refers to the two Magellanic Clouds, and "obscure" refers to the Coalsack.
Ferdinand Magellan sighted the LMC on his voyage in 1519, and his writings brought the LMC into common Western knowledge. The galaxy now bears his name.
Measurements with the Hubble Space Telescope, announced in 2006, suggest the Large and Small Magellanic Clouds may be moving too fast to be orbiting the Milky Way."
The Tarantula Nebula is a region of glowing hydrogen gas within the LMC. It is extremely luminous, so much so that if it were at the distance of the Orion Nebula it would cast shadows.

Paid yet another visit to Aladin's cave today (Lamb Engineering)
This is Larry's new engine which will feature in his entry to the AMD World Championships Bike build off later in the year..
It's a single cylinder around 600cc with the head being machined from solid brass..
The frame and forks for the bike have been machined from aluminium, with the exposed gearbox being an integral part of the subframe..
If you behave I may post a picture of it...

This was the first clear night in some weeks in Toronto. Yes it was very cold, but this was the day when I received my new Nikon Z7 mirrorless camera, and I just had to try it out on the Full Moon. Actually, the Moon was not yet quite full when I got the subframes from which this image was made; it would not reach its full phase for another 2 hours, 26 minutes. Also, the Moon was 5° south of the ecliptic, so we could look "over" the north limb (or edge) of the Moon's disk, and see some of the shadows inside the craters along the north (upper) limb that are apparent in this view.

Description:
The constellations Leo, Ursa Major and Canes Venatici, which are well seen in the northern hemisphere spring, are populated with many galaxies that can be seen in amateur telescopes, as long as the observer gets out of the light-polluted city and finds a dark rural sky.
Near the familiar star pattern of Leo (the Lion) are three bright galaxies that are favourite targets of amateur stargazers. M66 (lower left) is a spiral galaxy located about 31 million km from our Milky Way galaxy. It has loosely wound arms and prominent dust lanes, and recedes from us at the rate of ~700 km per second.
The nearby M65 (lower right) is another spiral galaxy that is a little fainter and 4 million km further away than M66.
Both of these galaxies were discovered by famed French astronomer and comet hunter Charles Messier on 1780 March 1 at the Paris Observatory.
The larger but fainter galaxy NGC 3628 (top centre, also called the "Hamburger Galaxy) is a spiral galaxy at the same distance (35 million km) as M65. Discovered by English astronomer William Herschel in 1786, this galaxy appears almost edge-on as seen from Earth, and has a very prominent dark dust lane along its outer edge.
Foreground stars to about 16th magnitude can be seen in this image.

Messier 3 (also known as M3 or NGC 5272) is a globular cluster found in the northern constellation of Canes Venatici. The image below was taken on April 23, 2016 from Weatherly, Pennsylvania using a Meade 12” LX-90 telescope, Canon 6D camera both mounted on a Celestron CGEM DX mount. Total exposure time was 3-minutes using 15-second subframes at ISO 5000.
M3 is one of the three brightest globular clusters in the Northern hemisphere (along with M13 and M5). I wonder what our night sky would look like if we were inside a globular cluster? I found an interesting little article here (www.astronomy.com/magazine/press-releases/2014/05/july-2014) worth reading. Imagine a sky with a thousand stars as bright as Sirius!

Description:
The centre of our home galaxy, the Milky Way, lies in the constellation Sagittarius, in the middle of the prominent bulge of stars and nebulae in this view, made with a wide angle 35 mm lens. Numerous star clusters, dark foreground gas clouds, and pink hydrogen gas nebulae are strewn across the frame.
The centre of the Milky Way lies very low on the horizon as seen from the northern hemisphere. Astronomers travel to the south in order to see the magnificence of the Milky Way straight overhead in the months of May-August.
This is the telescope and mount that I used for my astrophotography on this trip:

Special:
- Austin-Healey was a British Sports Car maker founded in 1952 through a joint venture between the Austin division of the British Motor Corporation (BMC) and the Donald Healey Motor Company (Healey), a renowned automotive engineering and design firm. Leonard Lord represented BMC and Donald Healey his firm.
- BMC merged with Jaguar Cars in 1966 to form British Motor Holdings (BMH).
- Donald Healey left BMH in 1968 when it merged into British Leyland.
- Healey then joined Jensen Motors, which had been making bodies for the "big Healeys" since their inception in 1952, and became their chairman in 1972.
- Austin-Healey cars were produced until 1972 when the 20-year agreement between Healey and Austin came to an end.
- The Austin-Healey Sprite was designed by Donald Healey as a low-cost Sports Car and production began at MG's Abingdon factory in March of 1958. Later models were also assembled in Enfield, New South Wales and in Australia.
- A few months later, the new car was officially introduced in Monte Carlo, just prior to the Monte Carlo Rally.
- In the UK it's called "Frogeye", in the US "Bugeye" and in Germany "Froschauge".
- The headlights mounted on the top of hood were "lifted" because of U.S. Import legislations.
- Concealed flip-up headlamps were in the original drawings but high production costs canceled those plans.
- To build this little 2-door Roadster they used Austin, MG and Morris parts to keep the costs down.
- The two front chassis legs projecting forward from the passenger compartment mean the shell is not a full monocoque. The front sheet-metal assembly, including the bonnet (hood) and wings, was a one-piece unit, hinged from the back, that swung up to allow access to the engine compartment.
- The engine for example was also used in the Austin A35 and Morris Minor 1000 Series and the rack and pinion steering was derived from the Morris Minor 1000 Series and the front suspension from the Austin A35.
- It has no exterior door handles and no exterior boot lid (the back seats would need to be folded down to get access, incl. the spare tire).
- The entire front hood hinged upwards, allowing easy and convenient access to the engine.
- It was made at the MG works in Abingdon and sold for £669, so the intention of keeping the price low worked.
- By the quarter-elliptic rear springs, a simple self-supporting body and little weight, the Sprite is a rigid car to drive: But real fun to drive ☺☺!
- They are still very popular for club racing.
NGC 3718, also know as ARP 214, is a distorted spiral galaxy in the Constellation Ursa Major and is located about 59 Million Light Years away. Its distorted form is thought to be gravitational interaction with the other galaxy seen in this image - NGC 3729 - at some point in the distant past. These are all part of a group of galaxies known as the Ursa Major Cluster.
One interesting footnote - below NGC 3718 you can see a small grouping of elongated shapes, very close together. While not shown very well in this image, this is a small group 5 galaxies known as Hickson 56. These Galaxies are estimated to be about 400 Million Light Years away!
These galaxies are very far away and very small. The largest here only measure 2.9" x 2.4" in size. I mention this because I really don't have a scope that is setup for these very small galaxies. SO why did I chose this target? Well, part of me wanted to see what I could do with it. Another part is that this time of year the number of targets is a bit limited - especially what I can access due to the tree lines on my property.
This is the third and last image to come out of my 3 night imaging cycle starting on June 4th. While we had three clear nights, we also had some bands of thin clouds that came through and the overall sky transparency was far from great. The thin clouds are not enough to lose a guide star and disrupt your runs, but they can ruin the contrast on critical subframes. In this case, I had to remove roughly 1/3 of my subs and it reduced the number of Green frames I ended with to less than half what I had for the other channels.
When first processed this image - it looked pretty bad. So I went back to square one, and this time I spent a huge amount of time working on the image deconvolution step. Some people think of deconvolution as a "Sharpening" step. In fact it does something quite different. Working it the frequency domain, it attempt to restore lost information caused by the optics. This is very tricky to use properly and for my first year of astrophotography I could not get any good results out of this at all. Then I got some help from Gary Optiz and Dan Kutcha and I was able follow a "recipe" and get some small advantage to my images. This time though, I really dug into it - played around with every parameter and saw how it impacted the image. At the end of it all, I had finally figured out how to use it properly, and I had a version of the linear image that had more detail than I had before.
With this I went forward and processed the image doing the bulk of the work in Pixinsight, and then shifting to Photoshop for the last polishing phases. I also used Topaz Denoise AI, on a few trouble spots along the way.
In the end - I was happy with the final result - but I also knew that to get the results I really want here I need a few things: 1) a scope with more focal length and resolution 2) Clearer and more transparent skies. 3) and a lot more integration time.
Thanks for looking!
