Hi all,

Have taken my first autoguided images of M42 last night and am somewhat disappointed. Would appreciate some constructive criticism. The problems with this image as I see them as follows:

1. Too much background light from moon, haze etc.
2. Not enough exposure (related to 1)
3. Vignetting

Image details:
Exposure: 3x30 sec & 1x30sec dark
Camera:Canon 10d
Scope: ED80
Autoguiding: Toucam/K3ccdtools
Guidescope: Tasco 50mm refractor
Mount: gm-8.

Do I need a flat frame to combat the vignetting, or should I try to make the light path wider?

Thanks in advance for you help,
David.
