I understand that 2" eyepieces have a larger field stop and let more light pass thru to the eye resulting in larger TFOV and brighter images.
What about the 1.25/2" skirted eye pieces? Aside from the convenience of not having to change the adapter at the diagonal ... does more light get thru than a 1.25". Is there any other advantage?
For example the Nagler 16, 12, and 9 mm pieces.
Thanks in advance howard
