The Heart Nebula, in the Cassiopeia constellation, ~7,500ly from us. This is my last image of 2024 due to weather and I only got ~13.5Hrs of data in Ha/Oiii only. #astrophotography @kat-astro-bot.bsky.social

The Pacman nebula, a bright emission nebula in Cassiopeia at ~9,200ly from us. Taken from my backyard in the Bay Area (bortle 7), ~45Hrs of exposure in Sii/Ha/Oiii. #astrophotography @kat-astro-bot.bsky.social

An image showing a glowing nebula with a bright central region, resembling the pacman video game character. The colors range from blues and greens in the center to yellows and oranges at the edges, all against a dark backdrop sprinkled with stars.

Close up of the Veil, on an area commonly called The Bat Nebula (NGC 6995). I'm starting to use Gemini to generate ALT text and it's both interesting and frustrating. It thought this looked like a Dragon, but the description is what it basically came up with.

An image of a complex structure in space featuring a long, vertical, undulating form resembling a celestial bat, composed of glowing filaments and wisps of gas and dust. The predominant colors are a soft teal or turquoise outlining the bat-like shape, with feathery red accents trailing along its body and edges. The background is a dark expanse speckled with numerous stars.

Eastern Veil nebula, a small part of a Cygnus Loop, a large (6x the size of the Moon) supernova remnant. This is ~2400ly from us. Taken from backyard in Bay Area. ~35Hrs of 5 min exposure in Ha/Oiii/Sii. #astrophotography @kat-astro-bot.bsky.social

An image showing a long, wispy structure resembling a curved strand or ribbon, composed of glowing gases and dust. The predominant colors are shades of red and a vibrant turquoise or blue, set against a dark backdrop speckled with stars.

The Lion Nebula in Cepheus. This is a region rich in hydrogen with emission nebulae and star clusters. It is slightly bigger in apparent size than the Moon! It is roughly 10,000 lightyear away. From backyard in the Bay Area. ~40hrs of exposure. #astrophotography @kat-astro-bot.bsky.social

An image showing a bright feature on the left composed of glowing gas and dust with yellow and orange hues, and a fainter, elongated feature on the right in bright blue tones, set against a dark backdrop speckled with stars.

Messier 13, a globular cluster in the Hercules constellation. Located ~23,000 light-years from Earth, and is ~145 light-years in diameter. It has between 300K and >500K stars! The Arecibo message was sent toward it in 1974. Full resolution at www.astrobin.com/full/faw5bf/0/ #astrophotography
