Celestron Ultima100 52252: Eye relief and Exit pupil problem

Postby AlphaD on Tue Mar 05, 2013 8:29 pm

I recently purchased a Celestron Ultima 100. I intend to use this for target shooting. I would like to improve the view, especially at higher magnification. I read Celestron spotting scopes have a 1.25 size zoom. Will I be able to purchase some aftermarket eyepieces that will allow me to be able to get a wider view on the occular lens and more exit pupil. I wear glasses and am over 50 years old. Some sites say this is not something I can add to my optic.

Currently I need to be able to see a 22 cal bullet hole clearly in a target at the following yardage: 50, 100, 150, 200, and further. The bigger/clearer, the better.

Thank you.

The exit pupil will remain constant no matter what eyepiece you'll get, assuming same magnification. The performance increase in the best eyepieces will still be minimal. You're asking a lot out of a $300.00 Celestron Ultima 100 (very good choice in that price range) that scopes costing thousands have a hard time doing. If you want to see .22 cal bullet holes at 200 yards and more, you'll have to use targets that can let you see the holes. Use sight-in grids or orange bullseyes or light paper with small aiming points.
