Cave Nebula, part one

September 1, 2022

The Cave Nebula (Caldwell 9) in Cepheus. I started the Ha run last night but Earth's atmosphere wasn't having any of it. Seeing was poor at best, and the random wisps of cloud passing through just made it worse. I stacked the first 30 subs just to see where it was going, and even with the excessive noise, I think this is headed in the right direction.
