Very nice.  I am in awe.  So far I have not been able to get very good planetary images.  But I am going to keep plugging away.

I plan to be out all night tonight.  I have a pretty full night in store, but hope to have time to capture Mars frames as well.  Hopefully I can get some better quality than I did before.

I was out again this morning at about 1:30 and seeing was good and no wind turbulence so I was able to stack 130/1300 frames per channel at f15.  I took the plunge and double stacked my barlows to get at least f30 (maybe even f50 looking at the image size) and the limits of seeing became very apparent.  I found that I had to hand select my sharpest frames because AstroIIDC seemed to be confused by the presence of dust motes perhaps giving false sharpness values.

I had wanted to compare how my C8 on a GEM would compare but it was getting a little too cold.  The 12" mirror was definitely instrumental in shooting Mars at 15 fps at 8 metres focal length!
