Did this one last night.<br /><br />10 x 30 second light frames at ISO 1600, 10 x darks removed, stacked and processed in deep sky stacker.<br /><br />Celestron Nexstar 11, equatorial wedge alignment, Canon 400D, prime focus on a waxing gibbous moonlit night. Also used one of those ambient light filters on the camera adapter. The resulting shot was a little darker, but way more detailed.<br /><br />http://www.aussiepeople.com.au/asignobservatory/Astrophotography.aspx<br /><br />Removing the darks seems to have made all the difference.<br /><br />Conversely, I opened the shutter on the same target and just let the telescope go with it's own tracking for fifteen minutes. (Fell asleep) Have a go at what it did! (Second image) I have no idea how to refine this tracking. I'm thinking when I get the ED80 on top, I will have to guide manually.<br /><br />Baz.
