    Don't hunt stars without it!
    If you're searching for a TELRAD sight for your telescope, it must be because you either had one before or tried one at a local star party. Either way, the first time you used a TELRAD, you probably said to yourself, "I've just got to get one of these."

    That’s what happened to us at Once we tried a telescope equipped with TELRAD's amazing instrument, we said to ourselves, "Our customers really need this." (Then we quickly installed TELRAD sights on our own scopes.)

    The TELRAD Reflex Sight is the bestselling non-magnifying star finder for celestial telescopes. Many astronomers simply will not own a telescope without one. Certainly any Dobsonian telescope owner should consider the TELRAD finder a "must-have" accessory, as it makes quick, easy work of locating and finding objects in the night sky.

    How it works
    The TELRAD projects three red rings spaced at 4 degrees, 2 degrees, and 1/2 degree in diameter. These rings are used to "star hop" to objects. If, for example, a galaxy is 10 degrees south of a star, you simply count two 4-degree jumps and one 2-degree jump, and you're there!

    The TELRAD is a super-comfortable finder to use, because you don't need to look "into" it as you do a conventional finder. The projected red circles are clearly visible, whether you're looking 2 inches behind the sight or 2 feet behind it. And because the sight doesn't magnify, you get the widest-possible field of view, making locating and centering alignment stars on GoTo telescopes a breeze. Even better, your view is correctly oriented, so what you see will match what's shown on your star chart!

    Easy mounting

    Connecting the TELRAD to your telescope is very simple. The included base can be permanently mounted with screws or with the included double-sided tape. The TELRAD reflex star finder sight uses two AA batteries for powering the illuminated rings. It's best used on large-aperture telescopes with bigger optical tubes, such as Dobsonians and Schmidt-Cassegrain telescopes.
