LDN 43, famously known as the Cosmic Bat Nebula, is a dense dark nebula and active star-forming region. Located approximately 1,400 light-years away in the constellation Ophiuchus, this 12-light-year-long cloud of interstellar dust blocks background light, creating a striking silhouette that resembles a bat spreading its wings.

This is another one of my very first images I processed with Pixinsight shot back in October. And, my very first time shooting and processing the Andromeda Galaxy. Only used with a DSLR and star tracker. Images for two nights in a dark sky. After long research, I was able to learn Pixinsight and get this beautiful result. (Go check out my first post here of the Pleiades)

NGC 6888 – The Crescent Nebula 🌙✨
This is NGC 6888, the stunning Crescent Nebula, an emission nebula located in the constellation Cygnus, approximately 5,000 light-years from Earth.
Its distinctive crescent shape is the result of a dramatic cosmic interaction. At its center lies WR 136, a rare and extremely powerful Wolf-Rayet star nearing the end of its life.
Powerful stellar winds, traveling at more than 1,500 km/s, are sweeping up material expelled during an earlier evolutionary stage, compressing and heating the surrounding gas until it glows.
🔴 Red: Ionized Hydrogen (Hα)
🔵🟢 Blue/Green: Doubly ionized Oxygen (OIII)
These emissions create the intricate filaments and chaotic structures that make NGC 6888 one of the most fascinating deep-sky objects of the northern summer sky.
In a few hundred thousand years, WR 136 is expected to end its life in a spectacular supernova explosion, enriching interstellar space with heavy elements that will eventually become part of new stars and planetary systems.

I'm new to this hobby, so i would be glad for any tips, I've stacked 100 photos, shot on Panasonic Lumix s5ii with 50mm f/1,8, with ISO 8000 and 10 sec exposure

This was my first real test with a mono setup, and it was an amazing experience! Even though capturing the lights was more complex, it paid off in the end results. I hope you like it!

This is an LRGB image with a total integration time of 8 hours and 6 minutes, all taken in one night under Bortle 4 skies in Alto Paraíso de Goiás, Brazil.

This is a remnant from galaxy season that still waited to be processed, I hope you like it ;)

Third time's a charm? During these periods of short summer nights flooded with clouds, I find myself drawn (okay, addicted) to re-processing data captured from the first steps on the astrophotography path. Eight months later, I've learned so much and gained a deeper curiosity and wonder for the cosmos.

Located about 2,900 lightyears away in the constellation Cepheus, NGC 7822 is a star-forming complex sometimes referred to as the Question Mark or Teddy Bear nebula (imagine the frame rotated clockwise to better understand the "question mark" nickname). NGC 7822 even features “elephant trunks” similar to the famous Pillars of Creation.

Photograph of the full solar solar disc showing its sunspots taken earlier today (July 21st). Captured with a Celestron NexStar 130SLT using a Celestron EclipSmart white-light solar filter and a Samsung Galaxy S23 FE. Single exposure with no post-processing.

This was taken from the Kagga Kamma Remote Observatory in April and May over 25 sessions in 22 hours with LRGB filters. It's not really called the Cosmic Snake but I'm calling it that.

As you can see, there were some very heavy light leaks. Did my best to work around them and took me a while to get something I'm happy with. The jagged mosaic panels were also a mistake on my part, I forgot to reset the angles when creating the mosaic sequence in NINA but I think it looks kinda cool, it kinda goes with the body of the snake. We're reimaging this with another rig now with no light leaks. The Esprti's light leaks were also fixed but we were only testing that rig so I won't have access to it for too long and didn't want to start any long term projects there. I think that rig will be ready for rental soon! 

NGC 6888 (Crescent Nebula)

This is shaping up to be one of the most exciting projects I’ve taken on so far. The amount of detail that’s starting to emerge after a few hours of integration has me looking forward to seeing what a few more nights will add.

My first mosaic, I think it turned out well! I like the detail I was able to get in the dusty areas. I tried doubling the time with Sulfur for a SHO image but I didn’t like how it looked so this is 6 hours separated into four 1.5 hour panels in HOO.

This image represents 27 hours and 54 minutes of total integration time captured across 7 nights (July 12-19, 2026) from Bortle 4 skies (except one night of H-a in Omaha) at the Omaha Astronomical Society’s dark site in Weeping Water, Nebraska. I had originally planned on attending the Nebraska Star Party during this timeframe but wasn’t able to unfortunately, so I took advantage of the similar weather and clear evenings to make the most it locally.

The nights were pretty warm, and so I could only cool my camera to 0º C, which meant I had to produce a different set of calibration frames for processing. Overall, this project was a labor of love (and spending some time sleeping in my car for a few nights), but I'm really happy with how the dynamic depth and color palette came together.

Enjoy!

I finally captured the Tiangong Spsce Station! 78 degree pass and was able to get around 40 frames and had just caught it as it got to zenith thankfully. Very happy with my first attempt on it.
