Baader LASER COLLI Mark III

The Baader Laser Collimator is an extrememly popular accessory that gives very accurate collimation (optical allignment) of all Newtonian and Schmidt-Cassegrain reflector telescopes, essential for getting the most out of your telescope. 
If your telescope is out of collimation, images will get distorted and you will not be able to achieve a proper, pinpoint focus at some higher magnifications, this small accessory fits into your eyepiece holder and assists in re-aligning your optics to correct these distortions (see instructions in Downloads)

Excellent value and performance at a fraction of the cost of other laser collimators.
