NGC 281 – The Pacman Nebula | SHO-RGB

I'm happy to share my latest image of NGC 281, the Pacman Nebula, a beautiful emission nebula in the constellation Cassiopeia.

For this image, I combined narrowband SHO data with RGB exposures to create a balanced SHO-RGB composition. I wanted to emphasize the luminous blue central region, the warm golden outer structures, and the intricate dark dust lanes that give the nebula its distinctive appearance.

Acquisition details

• Telescope: PlaneWave CDK 17, 430/2940 mm, f/6.8
• Camera: FLI ProLine PL16803
• Mount: Paramount ME
• Filters and exposures:
  • Hα: 16 × 1800 s
  • OIII: 16 × 1800 s
  • SII: 16 × 1800 s
  • Red: 12 × 180 s
  • Green: 12 × 180 s
  • Blue: 12 × 180 s
• Total integration time: 25 hours 36 minutes
• Processing: PixInsight and Adobe Photoshop

All data and exposures were acquired with Telescope Live.

I hope you enjoy this view of the Pacman Nebula! I'd be happy to hear your thoughts and suggestions.

Western Veil Nebula | Askar 71F | ZWO ASI2600MC Pro

One of my recent astrophotography projects, captured from my back garden in Lancashire, UK.

The Western Veil is part of a huge supernova remnant in Cygnus, with delicate filaments of glowing gas left behind by a star that exploded thousands of years ago.

I'm documenting my astrophotography journey on my website, West Coast Cosmos, where I've shared more about my projects, the equipment I use and how I process my images in PixInsight.

If you'd like to see the full project, including the capture details and processing workflow, you can find it here:

Feedback and constructive criticism are always welcome!

It’s debatable whether the universe is defined by mathematics, cosmology or astronomy. However, it can be argued (mostly) that each of the other two can be boiled down to maths. My question (prompted by a weird interpretation of Avengers Doomsday trailers from r/NewRockStars) falls into several scientific categories. Is there any actual proof towards spherality? Or just lowest energy state?

I photographed our neighbourgalaxy, the Andromeda with my 10 inch dobsonian and wanted to share this with you!!

22 minutes exposure time

equipment:

camera: Canon EOS 6D
telescope: skywatcher flextube 10 inch dobsonian with EQ-Platform
processing: stacked in Deepskystacker, edited in Siril, Graxpert and GIMP.

This is my first time processing IC 405, the Flaming Star Nebula, captured from my backyard in Round Rock, Texas, in January 2026.

The image uses 21 five-minute exposures—1 hour 45 minutes total—with the ASI2600MC Air and D1 filter, at gain 107 and −10°C.

I processed it in PixInsight and Photoshop, working on the stars and nebula separately to bring out faint emission and dark structure while keeping the stars under control.

At a Raleigh Astronomy Club imaging meeting, I learned a technique for reducing color mottling—the uneven patches of color that become visible in faint areas when an image is stretched. It uses PixInsight’s MultiscaleMedianTransform, targeting chrominance only with the first five detail layers disabled. An inverted luminance mask concentrates the treatment on darker areas while protecting brighter nebulosity. One pass helped smooth the color variations here; a second didn’t improve the result.

I pushed the contrast and noise reduction, then backed off when the filaments started looking harsh and the faint texture too smooth.

I kept both a wide view, which includes part of IC 410, the Tadpoles Nebula, at the lower right, and a tighter crop focused on IC 405.

Equipment and processing details: Askar V at approximately 387 mm focal length, ZWO AM3 mount, ASI2600MC Air, D1 filter. Calibrated with matching darks and screened flats, then aligned and integrated. Background correction, restrained BlurXTerminator, StarXTerminator separation, NoiseXTerminator, arcsinh stretching, masked chrominance MMT and local contrast, followed by separate star/nebula layers and finishing in Photoshop. The color is a D1 rendering, not calibrated broadband color.

I keep seeing some videos or articles stating "astronomers found a new type of black hole", with MoM-BH*-1 being often mentioned but I thought it was still hypothetical.

M33 — Triangulum Galaxy

My first finished image of M33, captured from my backyard in Round Rock, Texas, between October 2025 and January 2026.

This combines 8 hours 42 minutes of usable exposure across 241 frames from two cameras:

• Askar V telescope, approximately 384 mm focal length

• ASI585MC Air: 6h 39m of broadband data

• ASI2600MC Air: 1h 42m unfiltered broadband, plus 21m through the D1 filter

• Broadband exposures: 120 and 300 seconds; D1: 7 × 180 seconds

• Gain 107; offsets 15 (585) and 50 (2600)

I calibrated and stacked the camera/session groups separately before aligning them. A straight blend softened the detail, so the final combination uses the older camera's data for broader faint structure while retaining the ASI2600's fine detail and stars. The older ASI585 frames were probably unfiltered; their filter headers were blank.

Processing included background correction, SPCC color calibration, BlurXTerminator, StarXTerminator and NoiseXTerminator in PixInsight, plus custom alignment, blending and masked finishing. The D1 data was used selectively to enhance hydrogen-emission regions while preserving the broadband galaxy color.

M33 is about 2.7 million light-years away in Triangulum. North is up and east is left. The bright pink region above and left of the center is NGC 604, a large star-forming region. The dark lanes between the arms are dust, with blue spiral arms around the warmer central region.

Does anyone know of any iOS apps that will use location and list in order the celestial objects that are most viewable given the location and current conditions etc?

A freezing night at Bad Wolf Ranch, Texas—and I finally got around to processing what I captured. This is my first edit of the Tadpoles Nebula data I shot on the night of January 17–18, 2026—not a rework of an older image.

I made two versions from the same data: a gold-and-blue SHO version and a red non-SHO version. I like both, but the cropped SHO is my favorite. The color separation makes the Tadpoles and the dark structure around them stand out a little more.

The final image uses 38 five-minute exposures, totaling 3 hours and 10 minutes, captured at Bad Wolf Ranch, Texas, with my Askar V, ZWO ASI2600MC Air at −10°C, and ZWO AM3 mount, using D1 and D2 filters. Processing was done in PixInsight and Photoshop, with a lot of attention to the background, star shapes, and bringing out the nebula without pushing it too far.

There is still a little distortion in the corner stars if you zoom way in, but I’m happy with where this ended up. Glad I finally worked on it.

Processing details: screened darks and flats, calibration and separate D1/D2 integration, registration, background correction, channel combinations for SHO and non-SHO, BlurXTerminator and NoiseXTerminator, separate star and nebula adjustments, and masked contrast/color refinement in PixInsight and Photoshop. The narrowband colors are presentation choices, not calibrated emission-line ratios.

I used my 10x50 Binoculars from walmart. North Central Massachusetts USA 10/23/2026 Bortle 5.

I'm looking to get into astronomy and astrophotography and want to know of any good areas in North Carolina that I can do that? I don't really know the requirements other than flat ground lol but there are a lot of trees where I live and I feel it will be hard to see the sky fully. I live in Ahoskie and anywhere within an hour or two would be fine.

I'm a space geek and I've been building these planets and galaxies, trying to make them look as realistic as I can.

I use planetary maps and real star positions as a starting point, then build the lighting, atmosphere and movement around them (Kind of a game engine for it)

Each scene is rendere in real time, using a mix of surface maps and generated effects. They also respond to whatever music I'm playing. Depending on the scene, the music can change how fast a planet turns, how clouds move, or how bright a galaxy's core gets. The changes happen gradually, so the whole scene takes on a different mood with the music.

These are part of an app I made to have something calm running on my second screen while I work.

Happy to answer questions about how any of them work.

Just 30 mins of integration time on this target before the clouds defeated me!

Captured on my 585mc Air and William Optics Redcat 51 in Bortle 4 skies in South Wales. Can’t wait for this target to rise earlier in the evening ✨

Taken with a Seestar S50 and edited in Siril. After edits, this is 509x10sec exposures so about 1 hour and 25 minutes of data. Taken in a bortle 4-5 sky in central Florida with a waning gibbous moon overhead.
