my collection ... for use in f/5 Dob.
TV Nagler 5mm
TV Nagler 13mm
TV Panoptic 19mm
TV Panoptic 27mm
TV PowerMate 2x
Initially purchased low cost Meade & GSO eyepieces, but have now spent more on my EPs than on my Dob.
It's easy to rationalise about the please of wide/flat views, buying for the long term, and the high resale value of TV EPs .... but I think that a lot of us just get hooked on improving our setup.
Cheers.
