Hope someone can help me identify what I'm doing wrong with this type of shot - havent had time to check what it is, but I think it's M19, based on its approximate position.
You can see the problem - blurry stars and oversized! I am a rank newbie with the cam I'm using (Canon EOS 300d), and I had it set on ISO 800, bulb exposure of ~ 30 seconds, lens size (?) 90 mm. It is piggy-back mounted on the top of my scope.
Due to image size restrictions on IIS, I've had to crop this a bit.
Any suggestions??
