This low profile red dot finder is designed to fit the popular range of Sky Watcher Equinox (80mm & 66mm) APO refractor telescopes. The finder is supplied with a metal micro dovetail plate that attaches to the telescope with just one screw fastener (supplied). The finder will also fit other popular "clone" APO and Z80 type scopes in the 80mm and 66mm size range by Revelation, Moonfish, Orion, Scopos, Williams Optics and numerous others.
The great thing about this red-dot reflex finder is that it is non-magnifying and allows you to accurately point the telescope with both eyes open. Unlike optical finders, you donīt need to get your eye close to it - you can look along the telescope tube at almost any convenient distance to see the red-dot apparently projected on the sky. The finder doesnīt actually project the dot on the sky, but creates a clever optical illusion that by looking through the rear of the finder, it appears that the red dot is on the sky. This is probably the easiest type of finder to use for anyone new to using a telescope, but is extremely useful to experienced astronomers as well - a pretty unusual combination!
Supplied complete with battery.
