Hey Joel,
Good work, my first attempt at the lagoon looked like this.
So I decided to push it further. I can't remeber the exact details
but I did something around 15 sec exposures x 180 photos with
dark/bias frames at 6400 iso. so got the same setup I have a 10inch dobsonian With a goto. Try the lagoon again & also try the Carina Nebula (NGC 3372). You'll get amazing results
