Decisions, decisions ...
I feel I'm at kind of an inflection point AP-wise and need a shove in some direction. I've been doing AP for about a year, with a 150mm F-5 Newtonian, an Advanced VX mount and Atik 460ex mono camera (and an Orion autoguider setup). I'll never be Mr. Penrice but I'm slowly improving and get a lot of satisfaction from being able to "see" things through the camera that I'd never be able to see visually in our very light-polluted neighborhood. DSOs are my interest, not so much planetary. Budget-wise
OSC is absolutely not faster than LRGB. It may be less frustrating but it is not faster, it is significantly slower. (Any color filter, whether in a filterwheel or fixed over a pixel on an OSC, blocks two of the three colours so passes about a third of the light. In a 4 hour OSC shoot you therefore get 4 x 1/3 of the incident light. In an LRGB 4 hour shoot you get 3 x 1/3 during the colour stage and then you get 1 x all of it during the L hour. That is to say you get two additional 'thirds.' But
