Looking for opinions.
I've got an AT102EDL (F7) and case on order with Astronomics for $1225. The scope is FCD-100/Lanthanum F/7 doublet with a guaranteed minimum Strehl of .95.
While poking around on the Astronomics site tonight (it's raining!) I came across the AT115EDT triplet (which includes a case) for about $175 more. It's an LD glass F/7 triplet.
I plan to use the scope for both visual and ap and was drawn to the 102 because of the glass and Strehl ratio.
Here’s my question: the triplet design basically eliminates chromatic aberration, right? And with the 115 I'd get more aperture. Why wouldn’t I spend the extra money and buy the 115 triplet instead of the 102 doublet?
I've got an EQ6-R pro, so weight is not an issue either way.
Thanks for your thoughts!
