Description

Well, I've got some more "learn'n" to do here... Post processing was difficult because I didn't get enough subs... Thinking I might need to take longer than 10min subs... What do you think??? I have the CCD with a Baader Coma Corrector and the Celestron LPR filter installed on my f/3.9 scope... I figured it would be fast enough, but maybe the filter is cutting back? I don't know... I'm also getting some very difficult to remove graining going from upper-right to lower-left of all the images; I think it's the same problem that my other cameras exhibit, which means it's probably the scope that's causing it. The closest thing I can figure is that it's the baffles inside the OTA that are causing some kind of weird reflection of light off the inside of the scope and onto the primary mirror. I just don't know how to fix it!!!!
