Which one to keep?
As my clearance continues, I am now down to two imaging scopes: a TS80 f7 APO and the TS115 f7 APO. Which one to keep?
They both take the same 3" (0,79x) reducer corrector, and thus both run at f5,53 reduced. Regarding the colour correction, the 80 is an FPL-53 Doublet, and the 115 is a FPL-51 and Lanthanum Triplet (has a slight edge in performance, but is heavier of course).
So it comes down to focal length, weight, and correction. Opinions?
