Anthony... a nuvver fing...
Just noticed you quoted your FOV as 50deg on your observing log. That's the "Apparent Field of View". What you want is the "Actual Field of View" which is the Apparent Field of View divided by the Magnification. So with your 12.5mm ep giving a mag of 120X, the "Actual Field of View" is 0.42deg or 25 arcmins (60 arcminutes per degree)
You always see the abbreviation AFOV but I can never figure out if the A means 'Actual' or 'Apparent' !!! But it keeps me on my toes and makes me feel like singing.
