Telescopes with an optical finder

Optic

— seeker in the form of a monocular (spyglass) of small magnification, directed parallel to the telescope tube. Such a monocular usually has markings that allow you to accurately aim the optics at a specific point in the sky. Optical finders are much simpler and cheaper than LEDs, besides, the markings are perfectly visible against a relatively bright sky. In dark skies, however, problems may arise, but for this case seekers with an illuminated grid are produced. Thanks to all this, this option is by far the most popular.
