Probably my last view of comet C/2021A1 (Leonard). Schlepped out to Goose Pond Fish & Wildlife area in Greene County, Ind., a dark site with low horizons on a cold but crystal evening. The comet was very low by the time it got dark enough to emerge from the twilight so it appears redder than when higher in the sky. But I got enough exposures, to show some detail in the tail and coma. This is a composite, processed twice: registered on the comet and separately registered on the stars, combined in Photoshop.

I am very happy to present the second image in which these interstellar shells can be seen at all, and at the same time, it is the first photo to show the shells so clearly thanks to the long exposure time.
Thanks to several clear nights in the fall, I was able to collect nearly 39.5 hours of narrowband data with the RASA at f/2, along with an additional hour of RGB for the stars. The processing was certainly challenging, but I managed to bring out many details in the OIII structures and the surrounding H-alpha clouds.
A few details about the objects in the image:
The bluish filaments in the center are listed in Simbad as “interstellar shells” with the designation GSH 122+02-77. These are not direct supernova remnants but rather part of the interstellar medium (ISM)—low-density material (mostly gas) that exists between stars. Stellar winds and nearby supernovae can interact with this material, forming irregular shells. The neighboring Wolf-Rayet star HD 4004 (WR1) could possibly be responsible, although there are no definitive research results on this yet.
In the upper left, you can see Sh2-181 with a pronounced OIII shell, while Sh2-175, a small emission nebula, is located on the right.

The Veil nebula consists of different parts, each with their own designation. The best known ones are NGC6960, or the Eastern Veil Nebula, and NGC6992/NGC6995, or the Western Veil Nebula.
"The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus.It constitutes the visible portions of the Cygnus Loop, a supernova remnant, many portions of which have acquired their own individual names and catalogue identifiers. The source supernova was a star 20 times more massive than the Sun, and it exploded between 10,000 and 20,000 years ago. The remnants have since expanded to cover an area of the sky roughly 3 degrees in diameter (about 6 times the diameter, and 36 times the area, of the full Moon)."

The Iris Nebula can be a tricky target due to the amount of dust and dark nebulosity around, which can be easily mistaken for noise or light polution, but also equally it is very easy to over expose the core. Whilst I have some sort of reflection in the lower left corner, I am very happy with the way this image turned out, there's a lot of detail around the nebula

On April 15th, 2023 minor planet (270) Anahita passed by galaxy NGC 4939. I captured this encounter with a remote telescope in Auberry, California. Unfortunately this was about 16 hours after the close encounter, but the minor planet is still in the field of view. To my suprise I found an other minor planet, which is the still unnamed (35954) 1999 KY15.
The image is a stack of 20 frames of 180 seconds each. The minor planets are only shown in 7 frames each, to better show the movement.

The Cave Nebula (Sh2-155) is a Hydrogen cloud (in the center) with a brighter rim and a star forming region in the large molecular cloud known as Cepheus B. The stars of the Cepheus OB3 association are less than 100,000 years old. Low mass star formation is occurring at a high rate within the dust clouds of Sh2-155.
The blue reflection nebula (lower left) is VDB-155.
Just south (in this image to the left) of the Cave nebula we can see some strange orange Nebulosity, the home of some Herbig Haro Objects. HH168, HH169 and HH174 are locations, where a star is born, still surrounded by dust and nebulosity, already shaped into a rotating disk. This material blocks the light of the new-born stars and the pressure can be released only at the disk poles and Jets of material are escaping from their northern and southern poles.

NGC7882 is a large Emission Nebula in Cepheus, whilst I tried to obtain some OIII data, there appears to be very little OIII Data within this particular target. NGC7822 lies approximately 2900 light years from Earth and spans somewhere in the region of 100 light years across, there are a number of "Pillars of Creation" scattered throughout this large nebula.

I love imaging Orion. My goal with this shot was to include the Flame and Horsehead Nebulae, Barnard's Loop, Messier 78, and Lynds' Dark Nebula (LDN) 1622, the Boogeyman Nebula (upper left). It seemed like a good target for Halloween night.
I was excited to capture 30 minutes of imagery of my first comet, C/2017 T2 PANSTARRS, on Thursday, January 30, before clouds moved in.
Since I wasn't sure I'd get anything because of clouds, I didn't bother to drive to my Bortle 3/4 dark site, but instead shot from my Bortle 5 backyard, 60 x 30 seconds. I combined this imagery with some better imagery of the Heart and Soul Nebulae from this past fall (47 x 60 seconds under Bortle 3/4 skies), to create this small mosaic (the Heart and Soul Nebulae turned out a bit ugly from my Bortle 5 backyard). I was impressed with how well Astro Pixel Processor combined the imagery of such differing quality.

Finally had a clear night over a week after the launch of the NASA's James Webb Space Telescope and managed to catch an image of it on the way to its observation post. This is a composite of about six hours of exposures from suburban Bloomington, Indiana. JWST shows up as the streak to the left of the bright (relatively) orange star (HD 44256) as it moves relative to the background stars. The trail is interrupted because several bad frames (poor tracking, etc.) were excluded.

One of my favorite targets - the integrated flux nebula (IFN) or galactic cirrus is faint dust illuminated by our galaxy, and there happens to be a nice concentration of it in the direction of Bode's Nebulae (Bode's (M 81) and Cigar (M 82) Galaxies). The Angel Nebula, which is made of IFN, is in the lower left corner. This is an improvement over my last attempt at this target - shooting raw and more integration time made a difference.

This complex of reflection nebulae lies some 6,000 light-years away, in the constellation Cygnus.Obscuring interstellar dust clouds appear in silhouette against reddish hydrogen emission nebulae, along with the dusty blue reflection nebulae. Ultraviolet radiation from the massive, hot, young stars of the extensive Cygnus OB2 association ionize the region's atomic hydrogen gas, producing the characteristic red glow as protons and electrons recombine. Embedded Cygnus OB2 stars also provide the blue starlight strongly reflected by the dust clouds.

Fujifilm X-T10, Samyang 135mm f/2.0 ED UMC @ f2.0, ISO 1600, 41 x 60 sec, tracking with iOptron SkyTracker Pro, stacking with DeepSkyStacker, editing with Astro Pixel Processor and GIMP, taken Jan 10, 2019.
This is a reprocess of data from earlier in the year - this time I used the 'remove light pollution' and 'HSL selective color' tools of Astro Pixel Processor after integrating light frames in DSS and before editing in GIMP. Also, my flats were introducing artifacts so I didn't use them, but instead corrected vignetting with the 'remove light pollution' tool.
I'm much happier with this version - the color and definition of the nebula are much better, and seem to be accurate in comparison with other images.

30 * 60 sec subs
Gain = 300
Temp = -10 Deg C.
Mounted on the Sky Watcher Star Adventurer and calibrated using AstroPixel Processor. Lights only.
Taken at Dayborough, Queensland, Bortle 4
32 * 88 secs at ISO 1600, f6.1 - unguided tracking.
Although there is a degree of trailing on the stars, it's a pleasing result given that the lens is at 200mm, so a 400mm FF equivalent. (OLYMPUS M.75-300mm F4.8-6.7 II)
Used the Skywatcher Star Adventurer for tracking & Pole Master for polar alignment. Astro Pixel Processor for all the image calibration, only jpg as still learning software (lights and darks only) then export to Photoshop.
The 48 panel version does not show the Veil nebula so i decided to extend to 8x8 panels. This 16 panel (2x8) strip shows 2 main "attractions". This version is made with single 15 minute exposures using a 6nm Ha filter. (QHY16200/ Esprit 100 on GM2000 unguided) Software: Sequence generator pro/ Astro Pixel Processor.
Image reduced to 25%.
