Horsehead Nebula and NGC2023
Concluding my first Orion season with the Horsehead.
NGC2023 in the upper left was a nice surprise; next year, I'll be framing that in better. 🔭 #astrophotography

New astro image! 16 hours of imaging of the Horsehead Nebula and the reflection nebula NGC2023. My first project using an @antliafilter.bsky.social Triband filter. 🔭🧪

New processing on #Horsehead, I tried to play with the colours of the Flame Nebula (IC2024). It's not perfect yet and I lost some signal, so I'll try a new processing...

What's there @kat-astro-bot.bsky.social ?

So my target here was the little bright white emissions nebula NGC 2023 in the center, but I also serendipitously got nice shots of the Horsehead Nebula B 33 to the lower right and the Flame Nebula NGC 2024 at the top.

IC434, an emission nebula (red nebula in the background) with Barnard 33 a dark nebula known as the HorseHead nebula, and NGC2023 a reflection nebula (bottom left).

Nice! Reminds me of my own image of that subject with an off-the-shelf Pentax KIII. Considerably less than 6.5 hours though!! Probably more like 20 minutes. I am impressed that you managed to avoid reflections from Alnitak. My first attempt was ruined by flare off the corrector plate of my SN10.

IC434 es una nebulosa de emisión mientras que la flama es de reflexión. La estrella + brillante a la izquierda de IC434 es Alnitak del cinturón de Orión.Debajo se encuentra NGC2023, otra nebulosa de reflexión de color azulado.
