refractor choice
Hi,
tonight I *^*&^ my back trying to lift my newt/eq6 into position for the first clear night of imaging in a while. I'm over it. Now I'd like to replace the newt with a small easily moved refractor. It will be used pretty much strictly for imaging with my QHY8. The problem with the low end 80mm's seems to be that on an APS sized chip field curvature shows up, which means you have to crop the pic. Is there a field corrector (and/or reducer) that will work effectively with either an ed80, ed100 or WO zenithstar 80 11 ed (good price at the moment direct from WO), and result in NO need to crop pics? I know I want champagne performance on a beer budget, but I don't want to have to take pain killers every time I image!!! and I'm poor... The WO reducer correctors seem to have very patchy performance according to what I have been able to find. I did see the corrector tests here, but I wouldn't call any of the results spectacularly good. What about the latest incarnation of the P-Flat4? Feel free to berate me if I'm being unrealistic...
cheers
Gary
