Alpine Astronomical Planetarium Mark III Laser Collimator (Black)
Reduce your telescope s coma aberration using the Baader Planetarium Mark III Laser Collimator from Alpine Astronomical. This compact and lightweight device fits directly into the 1.25 eyepiece tube of your Newtonian or Schmidt-Cassegrain telescope and uses its 1.0mW laser to help you fine-tune your optics. It s body design features a cutaway side wall that exposes a screen perpendicularly oriented to the beam, with a hole for the passage of the laser beam and a grid of finely ruled etched crosses for viewing the returned beam. The pattern formed by the return beam provides the information you need to properly compensate for the distortion.
