Finding the right EP can be a little bit of a pain, especially for those of us who are fairly new. Attached is a fairly completed spreadsheet you can use for 1.25" EP selection.
Fill out the aperture and focal length of your scope.
Fill out your min and max pupil size (if known).
What will happen:
The magnification and exit pupil will update. They will also turn red if they are outside of the capabilities of you or your scope.
The true field of view will also update for you to compare. Instead of just relying on low, med, and high power, you can see that a 24mm 68deg EP gets you a wider FOV at a higher magnification than a 40mm, 40deg EP that has too high of exit pupil at too low of a magnification anyway.
Hold your cursor over one of the TFOVs to see the manufacturer, line, and price for that EP.
Any added lines that you guys find that I should add (PM me a link)
