- Inserts into the polar finder port at the back of the mount
- The easily identifiable star patterns of the Big Dipper, Cassiopeia and Octans are etched into the reticle, as well as Polaris and the North Celestial Pole, to help with alignment in the Northern or Southern Hemisphere
- Eyepiece has focus adjustments for reticle clarity
This polar axis finder is for assisting polar aligning your Celestron Omni or CG-4 mount. The finder is installed into the mount's polar finder port, located at the rear of the mount. Adjustment is available for focusing so that the internal reticle becomes sharp/in focus.
The reticle is etched with a few recognisable star patterns to help you align your telescope. If you are using your telescope in the Northern Hemisphere, you will recognise the Big Dipper asterism on the reticle, as well as the familiar “W” of Cassiopeia. Use the Big Dipper to guide you in the spring and summer months, and Cassiopeia during the fall and winter. The North Star, Polaris, is also designated on the reticle, as is the NCP, or North Celestial Pole. Once you choose which star pattern to use, align your telescope so that the stars line up with the positions shown on the reticle, then move the telescope’s azimuth and altitude adjustment controls to place Polaris in the crosshairs.
The Celestron Polar Axis Finder can also be used in the Southern Hemisphere. Four stars of the constellation Octans are etched in the reticle. Adjust your telescope until those stars line up as shown on the reticle.
