2" vs 1.25" EPs
[I'm sure this has been asked/answered before, but couldn't locate other similar threads]
On a telescope which supports a 2" VB, what advantages are there in using 2" over 1.25" EPs with identical FL and apparent FOV?
I'm aware of the FL upper limits due to barrel diameter.
In particular, does say a 25mm 1.25" EP use less of the light from a larger scope eg a 10" SCT than a 2" 25mm FL EP would?
Any comments or further explanations welcome!
