This is the Eastern part of the Veil Nebula complex in Cygnus. It's the remnant of a supernova that exploded 5-8000 years ago. The gas ejected from the explosion is still expanding outwards, colliding with other interstellar material at up to 30,000 km/s (one tenth the speed of light) -- the shock of the impact ionizes the gases, causing them to glow like this.
I've created a "bi-colour" image here -- a combination of just two channels -- with one channel in hydrogen-alpha (Ha) and one in Oxygen-III (OIII).
The image includes roughly 2.5 hours of exposure in Ha and 4 hours in OIII, through the QHY9 mono camera and William Optics FLT110 at f5.6. Stacked in DeepSkyStacker and aligned/processed in Photoshop.
Ha is mapped to Red, the Green channel is a 75-25 blend of OIII-Ha, and the Blue channel is a 90-10 blend of OIII-Ha.

A closer view of the comet between the trees at the bottom of our garden, just before midnight on 17/18 July. This is a manual stack of eight images in Photoshop - I could not get DeepSkyStacker to work on this sequence.
I think my source photos were soft and off-focus and this hasn't helped in the final image stack, where I used the comet head as the reference point.

The Triangulum Galaxy is a spiral galaxy approximately 3 million light years (ly) from Earth in the constellation Triangulum. It is catalogued as Messier 33 or NGC 598, and s the third-largest member of the Local Group of galaxies, which includes the Milky Way, the Andromeda Galaxy and about 44 other smaller galaxies.
With a diameter of about 50,000 light years, the Triangulum galaxy is the third largest member of the Local Group of galaxies. It may be a gravitationally bound companion of the Andromeda Galaxy Triangulum may be home to 40 billion stars, compared to 400 billion for the Milky Way, and 1 trillion (1000 billion) stars for Andromeda. from wiki

I never get tired of the Cygnus region.
Three clear nights on the bounce - whatever next?! :)
Took advantage of the weather to give this a really good crack, something I've been waiting to do since the arrival of the ED80. This is full frame, so the focal length is ideal. As near as dammit 8 hours total exposure, made up of various sub lengths and iso settings. The variation in iso seems to improve the overall noise in the final tif, so I was able to stretch this a little further (some would say too far!). Not sure if it's a little too contrasty - all a matter of personal taste I suppose. Overall, I'm very pleased with this :)

The Andromeda Galaxy or M31 as captured in a stack of fifty-four images that were exposed for 25 seconds each using a hand-driven, barn-door type tracking mount (two boards, a hinge, and a screw you turn by hand). This photo also shows Andromeda's two satellite galaxies, M32 and M110 (see image notes for the locations, M110 is the small elliptical galaxy slightly below center).
This photo was taken using a 50mm Nikkor AF-D lens on a Nikon D5100 DSLR and it is best viewed in the Flickr light box (press the "L" key to toggle the light box and optionally click on the "View all sizes" menu item to see the image at its largest size).
With the aid of the Cartes du Ciel star charting software (highly recommended free download) and with an examination of the area surrounding M110 I've determined that the limiting magnitude in this photo is around 14.5 (stars nearing the 14th magnitude are clearly shown, fainter than that are more difficult). There is also a definite halo around the small satellite galaxy M32, a detail which was not that apparent in my earlier post.
The brightest star in this photo (above center) is Nu Andromeda at magnitude 4.5 and it is located just over one degree from the center of the Andromeda Galaxy. One degree is just about twice the apparent size of the full moon, so you can see that the Andromeda Galaxy (as recorded in this photo) is several times the size of the full moon.
Captured on September 28 and 29 between 11:34PM and 12:28AM PDT with a Nikon D5100 DSLR (ISO 4000, 25 second exposure x 54) and a 50mm AF-D Nikkor lens set to aperture f/2.8. Image stack created with DeepSkyStacker using 54 image frames combined with 27 dark frames (no flats or bias).

Last night was the first clear Moonless night for a while, so I drove an hour Southwest of Brisbane and took some test shots of some of the larger deep sky objects to see how my 100mm macro lens performs for astrophotography.
The Pleiades (also known as the Seven Sisters) is a galactic star cluster approximately 135 light years from Earth. It contains many young, hot blue stars, and the light from these stars can be seen reflecting off dust in the region.
This image is 30 x 30 second exposures in a Star Adventurer Mini tracker, with the lens at f/4 and 3200 iso. Processed using DeepSkyStacker and Lightroom 5.

Here's a crop of a photo of Comet Lulin shot with the Nikkor 200mm f/4 AI telephoto lens. I had the IDAS light pollution filter on the lens to help bring down the sky fog. There's still a bit of vignetting even though it's cropped. You can clearly see the dust tail (anti-tail) to the left of the comet. The proper tail is not that distinguished as it is projecting away from us. The bloated stars and Saturn were caused by me not using a smaller aperture.
Number 35 in the Messier catalogue, number 2168 in the New General Catalogue.
A quite beautiful open star cluster in the constellation of gemini. At 2,700 light years away it is filled with young hot blue stars, leading to estimates at the age of the cluster to be around 150 million years. Over 500 massive stars spread out amongst 2,500 stars, stretching over just 24 light years.
In stark contrast is the open star cluster NGC 2158 in the lower right corner. Much further away at over 14,000 light years, it appears much more condensed. The lack of any large hot blue stars gives away the fact that it is also much older at an estimated 2 billion years.

The Pleiades or Seven Sisters (Messier 45 or M45), is an open star cluster containing middle-aged hot B-type stars located in the constellation of Taurus. It is among the nearest star clusters to Earth and is the cluster most obvious to the naked eye in the night sky. The celestial entity has several meanings in different cultures and traditions.
The cluster is dominated by hot blue and extremely luminous stars that have formed within the last 100 million years. Dust that forms a faint reflection nebulosity around the brightest stars was thought at first to be left over from the formation of the cluster (hence the alternative name Maia Nebula after the star Maia), but is now known to be an unrelated dust cloud in the interstellar medium, through which the stars are currently passing. Computer simulations have shown that the Pleiades was probably formed from a compact configuration that resembled the Orion Nebula. Astronomers estimate that the cluster will survive for about another 250 million years, after which it will disperse due to gravitational interactions with its galactic neighborhood.
Known as the Cocoon galaxy.
The smaller companion galaxy is NGC 4485. Referred to collectively as ARP 269.
The galaxies passed close to or through one another sometime in the past and, it's almost certain gravity will bring them back together several billion years in the future.
The red/pink areas are prime star forming regions where dense clouds of ionised hydrogen are irradiated by ultraviolet light from the hot, young stars within.
ARP 269 can be found in Canes Venatici some 24 million light years away. The two galaxies having now passed by one another are now approximately 24,000 light years apart.

The Ring Nebula (also cataloged as Messier 57, M57 and NGC 6720) is a planetary nebula in the northern constellation of Lyra. The tiny white dot in the center of the nebula is the star’s hot core, called a white dwarf. M57 is about 2,000 light-years away in the constellation Lyra, and is best observed during August. Discovered by the French astronomer Antoine Darquier de Pellepoix in 1779, the Ring Nebula has an apparent magnitude of 8.8. It is easy to find, as it lies about halfway between the two 3rd -magnitude stars “Sheliak” and “Sulafat” which form the bottom of Lyra’s lyre; however, it requires a moderately-sized telescope to see its beautiful ring-like details.

Memories:Fog descended on first evening so target resumed a couple of days later on a clearer night.
M65, M66 and NGC 3628; 30 million light years from home.
I was going to crop this tighter around the galaxies, but then I noticed a telltale streak on the left side of the image. After consulting Cartes du Ciel I discovered it was asteroid 128 Nemesis, which - despite its ominous name - doesn't come anywhere near the earth. (It's currently at a very safe distance of 2 Astronomical Units.)
Total exposure time: 85 mins
Telescope: Tele Vue-60 APO refractor
Mount: Vixen Super Polaris
I had to try it. Not an amazing image, but I'm happy with it considering the short focal length.
Acquisition details: Fujifilm X-T10, Samyang 135mm f/2.0 ED UMC @ f2.0, ISO 1600, 96 x 30 sec, tracking with iOptron SkyTracker Pro, stacking with DeepSkyStacker, editing with Astro Pixel Processor and GIMP, taken on Apr. 16, 2020 under Bortle 3/4 skies.
I processed with 3x drizzle in DeepSkyStacker, but I don't think it made much of a difference; I think my tracking accuracy limits the amount of detail I can achieve on tiny objects with my setup, and possible my sensor. Even though it's tiny, this is still a fairly big crop.
I plan to shoot M 101 next time - my attempt a year ago was marred by windy conditions. I probably won't bother with 3x drizzle, but might still apply 2x drizzle.
