Thanks Roger
Well you can...just costs more money
It is a 2.5 deg diagonal field at 1.57"/pix
I think I could still tweak the corrector spacing and maybe collimation a tad, the rest is image plane tilt and flexure, not sure I can ever eliminate the last two 100% with this OTA design, it is already acceptable to me but once I get her permanently under a dome (soon) and have more time, I will play with that corrector spacing and maybe I can shim something...?
