Hi,
I have a 9x50 (celestron) finder on my c8, have lot of problems with contortion. I read sometime back about a mod by Tom Mengel. He suggested using an ep from old binos along with a 90 deg or 45 deg diagonal. The method involves cutting 1/8 sections of the finder and checking every time for focus at infinity. I tried to see whether I could get a clear image with my 45 deg diagonal with a 30mm plossl ep, by moving the objective closer or farther away. I could never get focus. I want to check before I start cutting the ep end of the finder. Will someone suggest an easier way to modify this finder. I would like to get Tom's email so I can ask him. Jay
