Why isn't my field of View any larger?
My photo's on my Meade LX200GPS 10" F10 have always been smaller than predicted with CCDCalc. And my image either through the eyepiece, with ~20mm eyepieces, or with my camera has always been smaller than I'd think or predicted too; Talking of Jupiter in this case, is only about 3/16" at about 100-200x magnification. And I've never seen on Jupiter any more than the equatorial stripes around it with an eyepiece view. No Red Spot. Any advice Why my views and images are so small?
I can provide pics if needed.
