For many eyeglass wearers, the binoculars can replace their eyeglasses. First of all, the coating has nothing to do with the mineral ruby. Some manufacturers filter red to compensate for poor-quality optics that do not properly converge the color spectrum. By eliminating red from the spectrum, the optics appear to do a better job of minimizing color abberations- but gives the view through the binoculars an unnatural greenish cast. Be aware that this is a scam.
Tripods are pretty much a necessity for large binoculars, especially when used for astronomy.
It might be just fine. The tripods we sell are extra tall and sturdy- so that you will be able to view to the entire sky while standing, without having to crouch down. You need to get your body right up against the tripod- and the handle is in the way unless it extends forward. Your arm will be more comfortable reaching forward than crammed up against your chest. You'll also find that the tripod head will now allow the binoculars to point straight up.
