Baader laser collimator (Mark III)

The Baader laser collimator is not only eye-catching because of its unique shape. In contrast to the 3-4 mm exit laser beam of common laser collimators, this type has an exit laser beam of only 0.8 mm, which makes the alignment of the telescope much more precise. The reflected laser beam can be viewed through a transparent glass.

Also, the Baader laser collimator has the advantage of a 1.25" filter thread, with which the appropriate barlow lenses can be screwed on and used for collimation.
