I currently own an original AT72ED. After some recent scope purchases I am considering upgrading to the AT72EDii. This would be used for photography and some visual as well, giving me a wider field than my C80ED and my 102ED. I am considering selling my C80ED and my original AT72 to fund this. Is the quality increase of the new version worth the moves that I am considering?
I replaced my AT72ED with an AT72ED2 for visual astronomy. After selling my AT72ED, the swap cost me about a $100, which provided the following benefits:
- An R&P focuser that I like much better than the crayford that came on the AT72ED.
- Rings and a base instead of a mounting foot that came on the AT72ED, making the scope easier to mount and balance.
- FPL53 glass rather than FPL51 glass, which should provide less chromatic aberration, but I don't see much difference in the views through the EP.
