![]() Do you have any thoughts on this matter Koshkin? |
As a matter of fact I do. Generally, if you have a question for me, start a thread and shoot me a PM with a link. Otherwise, I might miss it.
The overall imae size is strictly a function of eye relief and eyepiece diameter. Your eye has a particular field of view and the more of your eye's FOV the eyepiece takes up the larger the image will look.
The presence/size of the black ring around the image is a function of the optical design of the eyepiece.
