any easy way to work out degree of viewing. ie with 1250 fl and 25mm ep, what is the way to calculate degree of viewing?

Davo, the FOV in degrees can be worked out by dividing the E/Pc apparent fov by the mag. eg; a 25mm E/Pc with a 40??? deg app.fov in your t'scope @ 1250 mm,> 1250 div by 25 = 50 x. The apparent FOV then is 40??? div by 50 = .8 deg. # of Arc minutes > 60 X E/Pc deg, eg; 60 x .8 = 48 A/M. So if you have an object which is 45 x 20 A/M, you can select the correct wide field/low power E/Pc to find/view it ALL & then up your E/P to a higher power to pick out more detail.......... HTH.

ps. Don't know what the app fov is for your E/Pcs. Could be 50 degs. Anyone know?? L.
