Contact JMI and mention Red-tagged Polar Scope when placing order.

The polar scope
allows a telescope to be quickly and easily aligned with the North or South pole.  Once mounted, a time consuming initial alignment must be made using the star drift method (except when installed on a Losmandy G11 or similar telescope which has the proper size mounting hole and threads machined into the mount).  All subsequent alignments will be as good as this initial alignment but far less time consuming.  To do an alignment, you simply rotate the scope to align the constellation reticle with your naked eye view of the sky then adjust the telescope mount to align two stars with the reticle.
