Hope I'm not comparing apples and oranges here but does anyone have an opinion on using a suresharp vs. a flip mirror to focus a C-8? Can truly accurate focus be obtained with a properly parfocal flip mirror system? If so it seems much easier to use than a suresharp (or other ronchi screen). Any feedback would be much appreciated. Thanks!

Hi, I'm new to imaging/processing and would like to know if anyone can explain what this strange haze is surrounding M31. Is this a processing issue or something I'm doing wrong at the camera? All the subs (about 20) were of varying lengths and iso's in a 400D. All the subs were also very short (<30 secs each) because I didn't get my shutter release cable for long exposures until after these shots were taken. Combined in MaximDL and raw images processed by Canon ZoombrowserEX. Thanks for any input/help!
