APM 2 Inch Coma Corrector Telecentric 1.5x Barlow Lens

APM 2 Inch Coma Corrector Telecentric 1.5x Barlow Lens was designed by well known physicist and optical designer Philipp Keller. The Telecentric 4 lens design prevents the need for distance to be individually adjusted for each eyepiece. Optimum distance is automatically achieved by simply inserting the eyepiece into the included 2″ adapter sleeve.

Calculated to yield a large back focus when used as an optical glass path corrector with coma-correcting effect combined with binocular viewers.  The large back focus also allows the use of an off-axis guider + filter + CCD to take photographs with full format chips.
