Newtonian f/5.6 and coma corrector with APS sensor, needed or not?
I intend to use my old 10" Newt (permanently mounted on EQ6, with enlarged secondary) for AP with DSLR (APS format).
For this setup I an not sure I really need the coma corrector... I definitelly don't want to spend too much, I am already in trouble with SWMBO..
Any thoughts about low-cost solution?
Thanks in advance!
