Exit pupil in high/low magnification help?
Hi there
Was wondering how much of a difference would there be if looking at say for example Saturn in a 25mm eyepiece F5 (exit pupil 5mm) compared to 10mm ep (2.5mm exit pupil)? Will you see much more detail with a exit pupil of 5mm compared to 2.5mm?
I'm 25 yrs old and assuming eyes have dilated to max in dark night, many thanks for your help.
