Straight-through finderscopes can be a literal pain in the neck when looking at high inclinations, especially 45° and above. They are nearly impossible to use when pointing at the zenith.
Upgrade your telescope (and save your neck) with this Antares 7x50 right-angle finderscope.
The objective lens assembly is fixed in place, and so the eyepiece is slid up or down and then locked into place for focusing the image of the sky. The eyepiece has its own helical focus for obtaining a sharp image of the reticle.
This finder produces a mirror-reversed image because it uses a standard, single-surface mirror for erecting the image. And so the Image has the same upright but mirror-reversed image as do such telescopes as refractors and Schmidt-Cassegrains using standard mirror or prism diagonals.
Six nylon thumbscrews effect alignment with your telescope. The mounting is of the quick-release type, utilizing a nylon thumbscrew. The mounting base has a curved underside for attaching to tubes and cells, and can be affixed to flat surfaces as well.
