Hi all,
Ive got some collimation problems with my Celestron UpClose 10x50 binoculars - give a slight 'double vision' effect. I've been able to re-collimate a pair of AOE 20 x 80 triplets before, does anyone know if it can be done on the UpCloses?

Cheers!

Tammy Plotner speaks about them - saying that after rough use they did not need collimation. We should extrapolate from that statement that they could be collimated if necessary?

The images suggest a fairly standard design so I expect you'll find the prism tilt screws under the rubber cover.

do they have a rubberised top or hard plastic where the collimation screws usually are? there is no reason why you should not be able to collimate, they aren't a waterproof bino

Thanks Eric and Daniel -

Collimation screws were in the usual place and it was quite simple to correct, many thanks for the tip!
