Hello, I'm currently trying to photograph different nebula with my unmodified canon 450d. My current telescope is a Skywatcher 500/102 on an az g02 mount. A few nights ago I tried photography the running chicken nebula, but after taking a photo I saw no sign of any nebula. The settings I used were an exposure of 30 seconds, and an ISO of 1600 which is the max my DSLR can go to. I haven't done any dark, or bias frames as this was my first time doing deep sky astrophotography. I've attached the photo to this article. Can anyone give me some advice on which I can do to help increase the visibility of nebula.
