Mount for 25×100

Hello Kevin, maybe you can help me. While I am waiting for my bino’s, I am trying to figure out how to convert my azimuth telescope mount to adopt the 25 x 100 binoculars. I have attached an image. Any ideas?

That’s an equatorial mount, which means it’s designed to be polar-aligned, so it can then move on just one axis to compensate for the earth’s rotation. This works fine with telescopes, but is not recommended for binoculars as the binocular must remain level to comfortably view with both eyes. It’s possible to maneuver both axis to keep the eyepieces level, but it’s not ideal. There are two other issues-
1) The plate that adapts the telescope to the mount must be removed and then attached to the binocular. The plate is probably attached to an internal backing plate- which may freely move around inside the telescope if the screws are removed. Not sure of compatibility with that plate, the binocular attaches to a mount with a single 3/8-16 or 1/4-20 screw (the mount hole is drilled and tapped 3/8-16, but a 1/4-20 reducer sleeve is included).
2) The 100mm binocular is 10 lbs., and far outweighs the 60mm scope that the mount and tripod was designed for. If you do manage to attach it, it’s not going to be very stable.
Most customers use our Series 5000 tripod/head ($279). The head is rated for 16 lbs., the tripod for 24 lbs., so easily handles the 25×100. With the included dual panning handles, it’s easy to steer the binocular in altitude and azimuth. It also has a crank-up elevator to compensate for changes in eyepiece height when panning from horizon to zenith. So that’s my recommendation, but if you still want to try the scope mount, I’ll do my best to help.
Regards,
Kevin
