I'm really new to all this but I think things are coming together a little. I have some questions I'd like to ask if I may? My imaging train so far is a CPC 800, 2X (2") barlow, and a Canon 50D. I'm controlling the 50D through BackyardEOS. I've had problems eyeballing a bright enough image through liveview, so I take a quick 500 frames, run them through Castrator, and then open that in VirtualDub to get a histogram. Last night I finally settled on iso 800 with 1/40 shutter speed. Then I take 2000 frames, run that through VirtualDub to massage the histogram a little, and then open in Registax. I then use on of the RankinStudio Youtube guides to process in Registax. As soon as I start applying wavelets I get a blue ring around the inner circumference of the planet. I can't seem to get rid of that ring, and that's before PS Elements. My questions are:
1) Should I keep up with the 2" image train or go to a 1.25" run?
2) If anyone is using a similar scope, camera, and BYE, would you share what iso and shuttler setting you find successful?
3) Is all the stuff with Castrator and VirtualDub unnecessary?
