For Astro-Physics mounts, this polar scope will allow you to quickly align your mount on the pole stars to ensure greater tracking accuracy throughout your observing session. The reticle was designed for use in both the Northern and Southern hemispheres. Even users of the GTO computerized mounts will find these polar scopes useful, particularly if your telescope is not orthogonal to the mount.
The unit threads into the base of the polar axis of all past and present models of the 400, 600, 600E, 800, 900 and 1200 German Equatorial heads (except the first black 1200 mounts that were produced). The illuminator, with red LED, allows you to see the reticle at night. It can be powered two ways:
AA batteries with battery pack and Cable that plugs directly into mount. 800 mounts require part #E0187 (RCA phono to 3.5mm adapter)
Parts included: Polar alignment scope with cover, reticle with short cable, battery pouch with two AA batteries, 27.5" cable to power the reticle from your mount (CABPAS3). New condition.
