Someone has to stick up for them poor defenceless 1.25s.
So here's another picture.
Top row, all 2": 27mm Pano, 30mm Superview, 17mm T4
Bottom row, all 1.25": 26mm Meade 5000 PL, 13mm Stratus, 10mm XW
The real diff is that the true FOV of a 1.25" vs 2" is limited by barrel size to approx 1600 vs 2000 degrees divided by the focal length of the scope in mm. e.g. 10" Dob with FL = 1250mm: Max possible true FOV of 1.25" EP is 1600/1250 = 1.3 degrees, of 2" is 2000/1250 = 1.6 degrees.
