VdB 14 and VdB 15 captured from my dark site in southern France end of September 🇫🇷 😊🔭
This was shot on the EdgeHD 8 with Hyperstar for a total integration time of about 5.5 hours using an OSC cam with just the UV/IR-Cut filter.

The California Nebula. It's around 5.5 hours taken with my ZWO 294MM camera and the new SVBONY dual narrowband 3nm filter. Color was added using my single emission line Ha and OIII filters (also around 5 hours each filter). #astrophotography @kat-astro-bot.bsky.social

NGC 281 (aka the Pacman Nebula) in SHO. It's about 20 hours total integration time taken with an f/6 scope and 294MM camera. I'm not quite sure it is finished, and feel like it needs another 40 hours, lol. But that's #astrophotography I guess. Maybe I'll try reprocessing. @kat-astro-bot.bsky.social

This is an SHO image of the Orion Nebula in disguise. I used pixelmath in @siril.org to make it mimic an RGB image. Total exposure time is around 12 hours, taken with an f/6 80mm refractor and ZWO 294MM camera. #astrophotography @kat-astro-bot.bsky.social

The Pacman Nebula NGC 281 in Cassiopeia had been on my wish list for several years, and now, over the course of 4 nights in September & October, I finally got it. Visually not an easy object due to light pollution, but really fun to photograph (tech. details in image) 🔭

Marrying H-alpha and LRGB data while doing #astrophotography can reveal cool things in space like those reddish jets of matter coming out of the nucleus of M82 (a buddy of M81, one of our neighbor galaxies).

This is the Horsehead and Flame nebula! It is a dark cloud of gas and dust in the Orion constellation. It is located around 1300 light years away. It is in a region where new stars are born! #astrophotography #astronomy #universe @kat-astro-bot.bsky.social

What's cool about #astrophotography 🔭📷 is that you can stack frames to create nice images, and also use those frames to do some aperture photometry (here with AIJ on the eclipsing binary V1337 CAS near IC1805 Heart Nebula AIJ). Ain't that cool people 🤓?
