The TV-102 is, to my understanding, a F8.6 doublet made with TV's own specification glass versus triplet in the TSA-102. I would lean towards the Tak triplet without hesitation for imaging however, in the context of visual astronomy does anyone think the doublet might have some advantage (this was reflected in Ed Ting's comments on the TV102) or perhaps I am just comparing apples and oranges here or Tak "super" APO's versus TV "ordinary" APO (I am being facetious here)
Thanks for the comments already - they are very much appreciated.
