Description

This is part of my process for optimizing EAA using a 14" Dobson and unmodified Canon 450D. I used Sharpcap to stack 561 x 8 second shots that I had previously captured and stacked between Feb 13 and Feb 23. ( total of 5 separate acquisitions). All modifications including dark and flat subtraction were made within Sharpcap, 3.3. No cropping or post processing of final image.
