Historical information::
Please refer to description below.

The following historical information is provided for your reference. 

This Polar Alignment Scope is identical to the PASILL4, except that the adapter was designed specifically for the 1.79" opening of the 1100GTO and 1600GTO.

The updated Losmandy 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.

The updated reticle is marked for epochs 2005 through 2030 and has been improved for users in the southern hemisphere. Even users of the GTO computerized mounts will find these polar scopes useful, particularly if your telescope is not orthogonal to the mount.  pasill4newreticle.jpg

The unit threads into the base of the polar axis of all past and present models of the 400, 600, 600E, 800, 900, 1200 and Mach1GTO German Equatorial heads (except the first black 1200 mounts that were produced).
