Thanks for the fast response Greg. I have spent a fair amount of time on the old astrobin checking out what these & other scopes can do, and its a great resource for sure.. even have my own little page on
there.
So all 5 of those have FPL-53 glass as it goes, and im sure all have pretty decent focusers (some rack & pinion, some not). I am ever so slightly leaning toward the 120mm but can i shoot at f/7, or will i have to spend the extra to get the x0.65 reducer which will end up netting me what could essentially be a very expensive Esprit 100ED (more or less).
