Hi -
I am a neighbor from the solar system forum and haven't done much deep sky imaging in a long time - but I did have a chance to image M57 from Black Forest Star Party this past weekend using my DMK21BF04 firewire webcam. The camera allows a maximum exposure of 30 seconds - the luminance for this image was created from a stacking of about 90 frames = 45 minutes of exposure through my A/P 10" mak/cass at f9.8. The color was captured at low resolution through a 4.1" refractor and RGB filters - and was compiled as an LRGB with quite a bit of tweaking in Adobe Photoshop using the techniques I use for planetary imaging.
I was excited to see that it is possible to get decent results on small relatively bright objects with the webcam.
