I took 10 images 2 nights in a row with my 10D for a total of 20. 5 minutes each at 800 ISO from Austin, Texas. TV85 mounted piggyback on a C11/G11/Gemini autoguided with a ST-237A mounted on my 50mm finder scope. Processed in Images Plus, Neat Image and Photoshop. Focused with DSLR Focus. I also used a IDAS LPR filter.
