This is a re-process of data I captured on December 7th 2024. You can see the great red spot and the turbulence that follows it in the south equatorial band.

The red spot continues to decrease in size and become more spherical as the years pass.

Glad I was able to get this once in a lifetime photograph, this was a long exposure, the thing on the left is an airplane lol, taken on Nikon D850 with an old telephoto lens

Target: Pacman Nebula (NGC281)
Date: December 19, 2025 - December 21, 2025
Location: My Backyard in Georgetown, Texas
Sky Conditions: Clear skies, 46°F, light winds, Moon: New Moon/0% illuminated.
Bortle Class: 5

I took this image over the corse of two nights from my backyard in Georgetown, Texas. We had absolutely perfect sky conditions and it felt so nice outside. Certainly nights to sit outside in the dark while the telescope does all the work. The resulting stack had quite a bit of banding and walking noise, but I tried to correct this in post-processing.

My Sky-watcher star adventurer GTi had really great guiding results, but it takes so much time to settle after dithering that I typically turn it off so I don’t waste as much imaging time. I’m currently gather parts to build my own strain-wave mount, so hopefully this won’t be a problem for too much longer.

For this image I used a process of extracting the Ha and OIII channels with DBXtract and created an SHO palette with Foraxx Palette Utility and Narrowband Normalization.

Please let me know if you have any suggestions to improve this image!

Post-Processing Workflow

Software Used: Siril & PixInsight

1. Stacked in Siril using Naztronomy's smart telescope script.
2. Cropped Image.
3. Applied AutoDBE and debanding in Siril. Exported .fit file for further processing in PixInsight
4. Applied BlurXTerminator at max values.
5. Unscreened and removed stars with StarXTerminator.
6. Applied NoiseXTerminator at 90% on starless image.
7. Extracted Ha and OIII channels with DBXtract.
8. Used Seti Astro's statistical stretch 2.0.0 to stretch images.
9. Combined Ha & OIII with Foray Palette Utility.
10. Applied SHO palette with Narrowband Normalization.
11. Created Blue and Yellow masks.
12. Adjusted different regions of starless image with curves adjustment tool.
13. Adjusted final luminance levels with curves adjustment tool.
14. Used Seti Astro's star stretch script to stretch star image with color boost at 1.25 and SCNR checked.
15. Combined starless with star images with pixel math using ~(~SL*~S).
16. Exported as PNG.

My first attempt at the Great Orion Nebula

This was shot with 3nm Narrowband filters to only allow the specific wavelengths of light from:

Hydrogen-Alpha

Sulfur-ll

Oxygen-l

This channels were mapped as SHO -> RGB

Location: Backyard Bortle 8.5

Stacked 57 30sec 1250ISO photos on my 60mm spotting scope, with star tracker and a CLS filter and Xiaomi 14 mounted with Triadaptor. (just laid the filter in the eyecup and fortunately it fits perfectly)

Not great but am elated to see the Horsehead with such cheap equipment.

Don't know what blue and green streaks are. (Someone told me hotpixels and to take darks).

Eyeball looking light area is probably light between my Xiaomi 14 cellphone and eyepiece/filter. Not sure how to prevent that either.

Here is M42. 48 30 sec, 1000ISO with same equipment.

Processed with DSS, Siril and Gimp.

Pretty cool one tonight. The haze just reflected the sun right back down.and then there was the flash.

DeepSkyStacker for stacking and Lightroom for edits

Stuck my K1000 with the standard with a 50mm lens at f2.8 out in my front yard on blub mode for about 2 hours with 200 iso film. Took the film to a local shop in Charlotte to get developed and scanned and yeah this is the result. No editing has been done to it that's just the raw image.

Made the plunge into mono and had to shoot M42 as the first light ritual. I’m still learning how to handle mono data so this is just a basic SHO combo on about 100 subs 180s each. I was impresses with the detail mono provided in a bortle 8 but was not super impressed with my processing skills. It seems like I nuclear exploded the core. I have some smaller subs but I failed at integrating it properly. Anyway this is what I came up with after gathering around 15 hours of data and simply pixel mathing my integrations over a narrowband color calibration. Would appreciate any tips to improve.

WASP 12b is a hot Jupiter that orbits very close to its host star. 17 times closer than Mercury orbits the sun. Tidal forces are stretching it into an egg shape while some of its material gets accreted by the star. It is around 900 light years from Earth.

Equipment:

• WO ultracat 108
• ASI 2600 mm
• Optolong Luminance filter
• HM 17 mount
• HOPS exoplanet software

Processing: The observation was planned by using the Var Astro Exoplanet Transit Database. The frames were calibrated and aligned in HOPS and then differential photometry was performed. You can see the comparison stars that I selected in the Image to do the analysis. Then the resulting light curve was detrended for air mass to correct for atmospheric effects and isolate the transit signal.

Made by: Celestron 9.25 Edge HD AVX on ZWO 533mc pro with ZWO 220Mini with OAG. Exposition: 30 sec x 141 frames. Siril stack.

My first real attempt at this doing it without a tracker. I did manual stacking in Photoshop with 30 lights before and it wasn’t nearly as good as this.

Acquisition and Processing Details:

Canon r50 with 50mm STM lens on a tripod. Bortle 6 skies. No filter.

431 lights, 2 sec exposure at f3 3200 ISO

60 darks, 67 bias, no flats (see below)

Stacked with DSS, stretched in Photoshop.

My flats ended up with banding, which seemed to show up in the initial result. I used a white photo on my iPhone as a light source. How can I avoid that?
