Thanks for the info, Chuck. Sounds like the eye relief is better than on my 20x80's. Patrick, how do I get you the $200 and pick up the bino's? Thanks, Wayne A. Sumner Math/Physics/Astronomy/Engineering Boy's Tennis Coach Northridge High School Davis School District (801) 402-8610

chuckhards@yahoo.com 09/24/06 1:59 PM >>> As a recap, this bino is the Apogee/Fotar/Celestron 25x100mm model. I measure the eye-relief at about 12-13mm, as measured from the glass surface to the Airy disk projected on a piece of wax paper. The rubber eyeguards fold-down. With my eyeglasses on and the guards folded, I can just see the entire FOV with the eyeglass lenses touching the rubber eyeguard. However, since my astigmatism correction is very small, I typically remove my glasses at the eyepiece and re-focus accordingly. And about focusing, this binocular has individual-eyepiece focusing, so each side must be focused independantly. Makes it tough on group observing. A heavy-duty tripod or parallelogram is required due to the sheer mass of the unit.

A terrific deep-sky binocular, and Patrick's price is pretty darn good, Wayne. I love mine. --- Patrick Wiggins <paw@wirelessbeehive.com> wrote:

I don't know and am not sure how to measure it. However, I think Chuck said he had the same binos so I'm sending this on to him to see if he knows.

Hi Patrick, Do you know how many millimeters of eye relief the 25x100's have?
