IC 2177 - The Seagull Nebula
Wed Feb 21 2024
After working on this project for a month and ending up with over 30 hours of total exposure time, I’m very happy to present my final image of this. I believe this is my longest integration yet as well as possibly the first time I’ve added RGB stars to narrowband data. Quite pleased with this one!
