I'd like to convert my 8x50 finder to use 1.25" eyepieces. Now it has a .965 diagonal and 20mm eyepiece. I was having a hard time getting it to focus so I moved the front lenses in about 1/4" so now it has a good range of focus. I'm getting a .965 to 1.25 diagonal but I need to know if I have to use the same 20mm ep with it. The closest I have is 14mm and 25mm.
Are there any good tutorials on distance from lense -> diagonal -> ep out there? I'd really like to learn what I'm dealing with instead of playing trial and error. A way to calculate a given power or something like an SCT 2000mm fl / 20mm ep = 100x power?
Any help is greatly appreciated.
