Description

APM’s 2″ Coma-Correcting Telescentric 1.5x Barlow was designed by well known physicist and optical designer Phillipp Keller, after multiple requests by APM customers.

The Telecentric 4 lens design allows for the end user to simply insert the eyepiece into the adapter sleeve and automatically achieve the optimal distance, without need for adjustments individually in each eyepiece.

This Barlow was designed to yield a large back focus, so that it can be used as an optical glass path corrector with coma-correct effecting when combined with your favorite BinoViewers. This large back focus allows for the use of an off-axis guider/Filter/CCD to take photographs with large and full format chips.
