51635 StarPointer Pro Finderscope by Celestron

Spend less time centering your target and more time stargazing with Celestron's new premium finderscope: StarPointer Pro. Traditional red dot finderscopes were originally created for shooting sports such as airsoftairsoft guns and shooting sports. StarPointer Pro was designed for astronomers by astronomers to provide the easiest experience locating celestial objects in the night sky. Whether you're new to the hobby or a seasoned amateur astronomer, you'll appreciate StarPointer Pro's thoughtful design features.

While a red dot can obstruct your desired target, StarPointer Pro projects two circular LED reticles. Just place your target inside the circles and it's ready to view in the eyepiece. The circles also serve as a measuring tool while starhopping. For added convenience, StarPointer Pro offers a 40 mm optical window with a large field of view.

StarPointer Pro attaches quickly to any telescope and secures with a dovetail connection and finger knobs. No screwdriver needed!

Get more out of every stargazing session with StarPointer Pro.
