The Telrad Finder Scope provides a non-magnified window on the sky and projects 1/2 inch, 2-inch and 4 inch illuminated red bullseye circles on the screen which can be brightened or dimmed for user needs. Simply place the star in the center of the bullseye and start star hopping! Both beginning astronomers and seasoned veterans alike enjoy the Telrad's red circle view because it makes it easy to compare to star charts and find objects. For example, a galaxy located 4 degrees southeast of a star becomes simple to locate because your visual reference points are clearly defined. No wonder the Telrad reflex finder is one of the most popular astronomy accessories!
Simply connect the included Mounting Base using either provided screws or double-sided tape, align, and you're ready to begin. Additional mounting plates can be purchased and your Telrad bullseye can be moved from scope to scope! Indispensable for accurately centering alignment stars for Go-To telescope models and a "must have" for Dobsonian users, the Telrad finder is so easy that even the youngest stargazer can use it... Even special star charts have been designed to work with this ingenious piece of equipment! Measuring 8.15 x 1.75-inches, the Telrad reflex finder requires two AA batteries and supplies hours upon hours of service. Simply switch it off between objects to conserve battery life - or leave it on and share with others where you're aimed!
