What to do if you can't find your eyepiece picture.

If your eyepiece does not appear in our listing, as a first step, we need you to send us a digital picture of the side view of the eyepiece. If we do not have any dimensions on file, we will ask you if you have access to a vernier calliper or micrometer. If you do, we will return the picture to you showing which dimensions we need in order to be able to make a swing out unit for you. If you do not have access to such tools, we may ask if you can send us the eyepiece for a couple of days while we take measurements.
