Polar Axis Finder for Equatorial Mounts

The Celestron Polar Axis Finder is an alignment accessory built for CGEM, Advanced VX and CG-5 equatorial mounts. It slides into the polar finder port at the rear of the mount to help astronomers and astrophotographers achieve accurate polar alignment quickly.

Hemisphere-Specific Etched Reticle

The reticle displays the Big Dipper and Cassiopeia star patterns for the Northern Hemisphere, with Polaris and the North Celestial Pole marked. Seasonal orientation lets you use the Big Dipper in spring and summer or Cassiopeia in autumn and winter for precise alignment.

Direct Port Installation with Focus Adjustment

Installation consists of inserting the finder into the mount's dedicated polar port and rotating the eyepiece until the reticle is sharp. The only common issue is forgetting to refocus the eyepiece after temperature changes, which blurs the reticle and reduces alignment accuracy.

Questions about this item

How does the reticle pattern translate to real polar alignment accuracy?

The etched reticle shows the Big Dipper, Cassiopeia, Polaris and the North Celestial Pole; you rotate the mount so those stars match the reticle positions, then centre Polaris in the crosshairs for near-perfect polar alignment.

What mount port does the finder use and does it require any adapters?

It slides directly into the dedicated polar finder port at the rear of CGEM, Advanced VX or CG-5 equatorial mounts; no extra adapters are needed.

What physical clearance is needed behind the mount to install and focus the finder?

The unit fits into the rear polar finder port and the eyepiece focuses by rotating its barrel, so allow enough space behind the mount to reach and turn the focus ring comfortably.
