Hi,
We had an OK night in NC last week, enough to get some pictures. Takahashi epsilon 160 (f/3.3) on G11 mount, manually guided, and Canon 20Da set at ISO 1600. No wind, quite humid, temperature 63F. The noise level in that camera is extremely low, which is very nice. I didn't see the red donught to the bottom right corner I usually get... The picture is a stack of 16 individual 3 minutes frames. All processing done in Photoshop CS (darks, contrast, curves, mask to bring out the faint nebula only, increased saturation a little) as I don't have ImagePlus yet to calibrate and stack correctly (flat field in particular). Thanks for looking
