Would you be able to elaborate on this one a bit more John. What are the big factors for the 26mm over the 31mm to you?
The 31mm would give a 20% greater actual FOV than the 26mm (91.3 v 76.1). I see the exit pupil is quite different 4.8 (26mm) v 5.7 (31mm).
I quite enjoy viewing open clusters and want to make sure I can get en eyepiece that will allow me to put it all in the eyepiece so to speak.
