When setting up Sky Tools 3 there is a place where you enter the EP that will be assigned to your scope. In that section you are supposed to enter the AFOV. The guys @ Astronomics told me to divide FOV by the mag in my scope. When I do this the image that Sky Tools produces is WAYYYY outside the possibility for my scope. Does anyone know if this is the correct fomula for calculating the AFOV for an EP?
Some of the things on CN that I have seen for doing it I have neither the equipment or the knowledge to do. There HAS to be an easier way! :help:

AFOV is usually provided with the eyepiece model. Plossls are generally 55 degrees, Naglers are 82 degrees, Es 68* eyepieces are, you guessed it, 68 degrees. You were given the formula for calculating FOV only you have AFOV and FOV mixed up.

BTW...Sometime I just sit and look at Rob Teeter's page. They are such beautiful scopes.... Maybe someday. I still have a lot of life left in my AD10 tho.
