Askar 0.85 Focal Reducer for 80ED Refractor - 80ED-085RED Pentax XW Eyepieces The MSD-DTL is a 90

The MSD-DTL is a 90 degree 1

the system disables all LEDs to ensure a fully automated and light-controlled astrophotography session

and that it is parallel to the focuser body surface

Low periodic error (< ± 7 arcseconds)

Askar 0.85 Focal Reducer for 80ED Refractor - 80ED-085RED Pentax XW Eyepieces The MSD-DTL is a 90The Askar 0. 85X Focal Reducer is designed specifically for the 80ED refractor. By adding this reducer to the optical chain of your telescope, the focal length will f 5. 9 for a wider field of view and faster imaging times. The reducer features a triplet optical design that includes one ED element. It is designed as a focal reducer but also provides some field flattening correction. This Askar 80ED . 85X Reducer is optimized for the APS C frame. The
