At the heart of the kit is a 5mW green laser pointer with a sharp, bright, clear beam. (Always remember a green laser pointer's performance depends on ambient light, collimation, temperature and battery power. A laser pointer that has been repeatedly dropped or abused won't work as well as expected.) The Celestron Green Laser Pointer Finderscope also comes complete with secure telescope mounting brackets: a dovetail that works with almost every telescope (some binoculars, too!) and a bracket designed for Schmidt Cassegrain telescopes.
Once mounted, simply use the the X-Y alignment screws to put your telescope's target "on the beam". The laser will project a bright green line against the physical sky - not a screen. No more uncomfortable positions when trying to look through a fixed optical finder - or a difficult to see red reticle. You can even remove the laser and use it as a hand held star pointer! Then just place it back in the bracket and you're good to go again. The Celestron Green Laser Finderscope Kit has also included a Complimentary CR123A Battery to get you started and it's covered by a Celestron Two Year Limited Warranty. You're gonna' love it... I love mine!
