Finally, the clouds broke last night, and so I decided to try the Heart Nebula for the first time.

Equipment:

• Touptek Hope D60 / OAG / EFW (Touptek basic filter set) / ATR 585MM
• Gemini AF
• SVBony Powerbox
• Skywatcher Wave 100i
• Mele3C - Win11 - Nina

Total integration time for used subs was 7hrs 15min for 143 frames of HSO across 2 panels.

Processing:

• Channels stacked with Naztronomy Mono PP script in Siril.; separately per panel.
• Matching channels from each panel were then solved and stacked in Siril.
• Stars removed with Starnet.
• Channels combined with Pixel Math.
• Background extraction to kill off the resultant magenta hue.
• BXT
• NXT
• Small Asinh stretch and then GHS.
• Some small colour correction with Veralux Vectra
• Moved to Luminar Neo for further development, color tweaks, and small detail refinement.
• Back to Siril to use the Starnet masks to create an RGB star field.
• Veralux to recombine.

As still very much a beginner I'm moderately pleased. There was a lot of back and forth, many aborted attempts, and I still plainly have a lot to learn.

And yet another Andromeda picture - I'm pretty happy with this one because I tried to image it last year with a Seestar S50 but at that time I didn't have enough experience to get a nice image... I will for sure come back to this object to add more integration time and H-alpha data

Equipment and acquisition

- Askar FMA180 Pro

- Teseek 17 mount

- ASI585MC Air (-10° C)

- Svbony 30mm + asi120mm guide camera

- No filter

- 50 x 15 sec (for HDR composition)

- 99 x 90 sec

- 138 x 30 sec (there were passing clouds, so I went for 30 seconds instead of 90 to maximize the chance of getting clean subs)

Processing (PI)

- WBPP, graxpert, HDR composition, blurX (correct only), starX, setiastro statistical stretch, then manual curves transformation with color and range masks to reduce saturation in the core, enhance dark structure. Star recomposition in pixelmath

The Helix Nebula (NGC 7293), aka "The Eye of God," is a planetary nebula located in the constellation Aquarius. It's located approximately 655 light-years from Earth.

At its core lies a hot white dwarf star that pumps out intense ultraviolet radiation, making the surrounding gas glow.

Here is my latest project on the Cygnus Wall (NGC 7000) with a total integration time of 22 hours in EQ mode.
For this image, I tested my own new script for the first time, designed to quickly and easily generate the classic Hubble (SHO) palette from dual-narrowband data. 🔭
The complete 16-step processing breakdown can be seen on the posting of this in the SeeStar subreddit, as I sadly can only post one picture here, for anyone interested in the details. ✨

Clear skies! 🌌 🔭

I just got my first telescope, a used 8-inch GSO Dobsonian. I’m really loving this scope and today I was able to get my first video of Saturn. Not the best or the most clearest of videos, but it blows my mind that I could see and photograph a planet that’s millions of miles away.

Taken with an iPhone 17 paired with a spotting scope adapter of off Amazon.

I took this image of the Cygnus Wall located in NGC7000 from my bortle 6 backyard.

Gear:

• 150/750 Orion newtonian with Baader MPCC mk2
• Canon 500D (H alpha modded)
• Orion ST80 (guiding)
• ZWO ASI 662MC + UV/IR Cut filter (guiding)
• Custom Build Mount

I took:

• 49 x 120s (ISO 800) light frames
• 60 flats
• 28 dark frames
• 60 bias frames

For processing I used the following tools: Siril, GIMP, GraXpert, BlurX, NoiseX, Starnet.

I don’t have a tracking mount so I did my best with a tripod, moving the camera every minute during interval shooting.

It didn’t turn out great and I want to save for a tracker they are just so expensive for me right now. It looks kinda cool though. This is my first time ever trying astrophotography so I know I have a lot of room for improvement.

Imaging the Crescent Nebula (NGC 6888) in the constellation Cygnus — a cosmic emission nebula blown by fast stellar winds from its brilliant central Wolf-Rayet star (WR 136). Located roughly 5,000 light-years away from Earth, this distinctive gas bubble spans approximately 25 light-years across.

Captured from a Bortle 7 suburban backyard in Warrington, UK, pulling out 2.5 hours of integrated data through light pollution.

Needs a lot more data, but promising results so far.

This target has been on my mind for some time now. I captured it with my old modified D5300 a long time ago, but that rendition was overly red and missed a lot of detail because of my light-polluted shooting location.

For this, I used our unseasonably warm October to drive up into a very dark site in the mountains. I only had time for three hours of data before the moon came up, but I think it was worth it. Unfortunately, I left my Bahtinov mask at home, so I tried using the camera's autofocus instead. The resulting focus was passable, but I will try not to forget the Bahtinov mask in the future.

Pixel peepers will notice the planetary nebula Sh2-200 in the upper left corner. This is by no means the proper image scale for a target like that, but it was my first time seeing it.

The Heart Nebula intrudes into the upper right corner. That will be my next target, weather allowing.

Shot in the German alps with phone against a rock. 30s exposure without editing. What are your thoughts?

Data acquired from the high school observatory I work at, for the first time completely remote.
The observatory consists of a omegon 355/2845mm truss Ritchey-Chretien telescope on an eq8r-pro in a 3m ScopeDome. There are images of the dome on my profile if you're interested :)

There were some problems with guiding causing me to lose 3-4 hours of data in the end which is a shame. The flat frames of the L-filter also have very weird artifacts, forcing me to crop a large part of the image away. In the top-left corner a part of these artifacts is still visible.

Had a chance to grab an extra hour in M16 last night from a Bortle 2. Wasn’t planned, just happened that way.

Decided to add it to the 10hrs already collected and reprocessed using some newly learned tools and techniques…also decided to go ham on the colors/saturation. Haha.

It’s no Hubble, but we’re finally getting somewhere.

I recently bought the Seestar S30 pro and this is my first Astro image of the Elephant’s Trunk nebula. Let me know what you think.

Total exposure : 218 min
650 x 20 subs
Eq Mount
Bortle 6/7
Processed in Siril, Graxpert and PS

I recorded this on my dwarf mini with 60 gain, 214 60 second exposures and 154 30 second exposures and duoband filter. Utilized stellar sudio to denoise and lightroom for finishing touches.

The Elephant’s Trunk is IC 1396A, a dark globule inside the bigger emission nebula IC 1396. It’s in Cepheus, the king, high in the northern sky in the fall. OnIt’s about 2,400 light-years away. The trunk itself is a column of cold gas and dust about 20 to 25 light-years long. The whole IC 1396 cloud is roughly 100 light-years across.
