Maximum useable Field of View
Posted 09 October 2003 - 03:05 PM
"A common mistake is to buy one or more expensive long focal length highly corrected 2" wide field eyepieces, and then attempt to use them in a two inch diagonal behind an f/6.3 reducer/corrector, thinking they'll get a wide enough field to see BEHIND them... But all they really see is the secondary mirror shadow obscuring their field of view and then get mad at the focal reducer."
- With other word what is the maximum Field of View with acceptable field vignetting for Meade 7" Mak and it's different for 1 1/4" or 2" diagonal - ocular and with or without focal reducer.
- What combination give maximum Field of view
- It's something different with binoviewer
PS: I don't need explanation of formula Field of View = eyepiece field of view/magnification. I'm asking these on many places, but without good answer. I need it to know what to buy.
