Here's one from last week with the newly refigured 10". I must say that my mount is not equipped to handle the 10" and I cobbled together some rings out of scrap wood. Add to that the lack of sufficient counterweights and I'm very pleased with this image! I didn't dare add a guide scope to the already overloaded CG5 mount so I used a Soligor 135mm f/3.5 lens w/Basler A102f mono Firewire camera. I had trouble finding enough weights to balance things out. I'm not sure if it was the lens type or the lack of balance but I didn't have much luck getting metaguide calibrated or working well. Guiding was pretty off and my stars got stretched. Here's andromeda @ ISO 1600 180s exposures... 23 of them but only stacked about 10. Processing is actually pretty bad now that I look at it. My 2-year old was getting into things so I rushed.
Photos of my rig will follow.
