Thank all for your visit and awards.
The Cocoon Nebula in Cygnus is a star-forming region with a diameter of about 15 light-years and lying several thousand light-years from Earth.
The nebula itself is powered by the bright star visible near it's center and contains a cluster of young hot stars. Framed against an extremely dense star field, it seems to punctuate the end of a sinuous 2 degree long dark nebula cataloged as Barnard 168. With the Cocoon glowing at magnitude 7.2, the blackness of the dark nebulae surrounding it makes for a wonderful contrast to the Cocoon itself and results in a spectacular view in larger instruments.
Image Details: The attached images were taken Jay Edwards on June 17, 2018 simultaneously using (left) an 80mm f/6 triplet apochromatic refractor (ED80T CF) connected to a Televue 0.8X field flattener / focal reducer and (right) a vintage 1970 8-inch, f/7 Criterion newtonian reflector. The 80mm was piggybacked on the 8-inch, and the scopes utilized twin (unmodded) Canon 700D / t5i DSLRs.
These optics were tracked using a Losmandy G-11 mount running a Gemini 2 control system and guided using PHD2 to control a ZWO ASI290MC planetary camera / auto-guider in an 80mm f/6 Celestron 'short-tube' refractor which itself was piggybacked on top of the 80mm apo.
The attached composite image was constructed using, relatively speaking, extremely small stacks of short 1 minute sub-exposures, and consists of only 20 minutes total exposure for the 80MM shot & 30 minutes for the 8-in image (both in addition to applicable dark, flat & bias frames), and thus contains far more noise than we would normally produce.
Processed using a combination of DeepSkyStacker, PixInsight and PaintShopPro, as presented here it has been re-sized down to HD resolution and the bit depth has been lowered to 8 bits per channel.
Given such short exposures I was intrigued by the results and look forward to taking deeper shots when this object is once again conveniently placed in our evening skies next summer.

Another attempt at the Andromeda Galaxy again taken from my garden in South Shields. This time I used a 2 x tele converter on my 180mm ED AIS lens and used a Bahtinov mask on the front to aid focus. 6 x 4 minute exposures at 1250 iso stacked in deepskystacker and processed in photoshop using Doug Germans tutorial on YouTube.
With a reducer-corrector I can get a wider field view of M42, but at the cost of over exposure (!).
Also I need to sort out some flat fields and reduce the vignetting there...

Image taken 29/09/18
A total of 11 exposures, 15 seconds each, taken with Pentax K50, 10 inch f/5 motorized (tracking) Dob, and ParaCorr Type 2 corrector. I used the corrector so the camera (with T-adapter and 2" nosepiece) could reach focus - why manufacturers continue to produce scopes that can't reach focus with common imaging steups is beyond me. The (Orion) Dob was only off by 1/2". Image produced using DeepSkyStacker in Comet Mode.
That's what went through my head when I first stumbled across the Double Cluster h & chi Persei (a.k.a. NGC 869 & NGC 884) through my small, newly-bought amateur telescope. Of course, when I recently had the rare chance of observing this magnificent pair through 16" double-newtonian "binoculars", the view was even more stunning...
Also astrophysically, the objects are something quite rare, as they appear to be two young open clusters that are not only a chance alignment, but actually gravitationally bound siblings!
Still, it's a great and easy-to-find object (actually even visible as a faint smudge to the naked eye under reasonable skies) that's a pleasure to look at in anything from handheld binoculars to high-end amateur telescopes. And it seemed a fitting target to try out my new camera, a Canon M50 Mk. II, together with the 1000 mm f/10 Maksutov lens, which frames the two clusters just nicely. Plus, it's close enough to the celestial pole that I can actually use the 1000 mm focal length on the Star Adventurer for once.
I'm quite happy with the new cam, as it also has a much more powerful live view than my old trusty Samsung NX30, making object alignment soooo much easier if you can also see a few fainter stars on the display.

An attempt at the M81 & M82 couplet in Ursa Major (plus a cheeky little NGC 3077). I tried applying a 2x drizzle this time since these objects were very small in the raw image at 200 mm. Between the drizzle and compounded crop factors, this is maybe 6-8 times larger than off the sensor. Seemed to work ok, but some of the brighter (larger) stars look a bit blobby and weird.
As ever, the trick really is just to get as many exposures on a given area as you can. More exposures = better image. It'll reduce noise and get better drizzle. I just find it difficult to focus on getting just one image in a two or three hour night when the sky is SO BIG and I only get out so often! It would also be good to get a telescope or tracking mount, but that's another issue...one step at a time.
This images is 50 exposures stacked with DeepSkyStacker, each 2.5 sec, f/2.8, 200 mm, 6400 ISO. (13 dark frames...also not enough darks)

The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula situated in the Milky Way, south of Orion's Belt in the constellation of Orion. It is one of the brightest nebulae, and is visible to the naked eye in the night sky.
M42 is located at a distance of 1,344 ± 20 light years and is the closest region of massive star formation to Earth. The nebula is estimated to be 24 light years across. It has a mass of about 2000 times the mass of the Sun.
Older texts frequently refer to the Orion Nebula as the Great Nebula in Orion or the Great Orion Nebula.

The Orion Nebula is a diffuse nebula situated in the Milky Way, being south of Orion's Belt in the constellation of Orion. It is one of the brightest nebulae, and is visible to the naked eye in the night sky. M42 is located at a distance of 1,344 light years and is the closest region of massive star formation to Earth.

Older texts frequently refer to the Orion Nebula as the Great Nebula in Orion or the Great Orion Nebula.
The Orion Nebula is one of the most scrutinized and photographed objects in the night sky, and is among the most intensely studied celestial features. The nebula has revealed much about the process of how stars and planetary systems are formed from collapsing clouds of gas and dust. Astronomers have directly observed protoplanetary disks, brown dwarfs, intense and turbulent motions of the gas, and the photo-ionizing effects of massive nearby stars in the nebula.saved with settings embedded.

First trial at using Nebulosity and FITS Liberator.
I didn't use anything particularly special to make this photo, I used a Canon 5DMkII with Samyang 14mm lens. I shot 10 photos, one after another, at ISO6400 for 15 seconds each. The lens was set to f2.8 and focussed on infinity. Each photo looked dim and uninteresting.
I then converted the RAWs to JPG (for memory consideration) and ran them through the free software DeepSkyStacker which puts the photos together and unrotates them so the stars don't 'trail'.
Then the combined image was processed in Photoshop to make the blacks black and whites white as the averaged photo has little contrast.
All this is from the data that I captured on location and it was in the Brecon Beacons in Wales! I'm impressed anyway :-)

Here's my other take at the moon just passing the Golden Gate of the Ecliptic on February 9, 2022. This close-up was taken with the Samsung NX30 camera and Samsung 50-200 mm OIS-III telezoom lens @ f = 70 mm and stopped down to f/6.3.
I really like how the Aldebaran and the Hyades cluster on the lower left and the Pleiades cluster on the upper right align almost perfectly with the moon. I'm also happy I managed to bring out some star colours, particularly bright orange-yellow Aldebaran.
