Celestron Polar Finderscope AVX / CGEM

Celestron Polar Axis Finderscope for CGEM, Advanced VX, and CG-5 Mounts

Achieve Accurate Polar Alignment—Fast, Intuitive, and Field-Ready

Fine-tuning your polar alignment is essential for precise tracking and successful long-exposure astrophotography. The Celestron Polar Axis Finderscope simplifies this process, offering a visual, star-based method of alignment without the need for electronics or external apps. Designed for CGEM, Advanced VX (AVX), and CG-5 mounts, it gives observers a reliable and intuitive way to get aligned and observing faster.

Designed for Northern and Southern Hemisphere Use

This versatile finderscope features a high-quality etched reticle tailored for both hemispheres:

• In the Northern Hemisphere, you'll find etched patterns of the Big Dipper and Cassiopeia, along with Polaris and the North Celestial Pole (NCP). These familiar constellations help guide your alignment year-round—use the Big Dipper during spring/summer and Cassiopeia in autumn/winter.

• In the Southern Hemisphere, the reticle includes four stars from the constellation Octans, allowing for precise southern polar alignment.

Easy Installation and Use

The finderscope installs directly into the polar finder port located at the rear of your compatible mount. Once inserted:

1. Focus the eyepiece until the etched reticle is sharp and clear.

2. Locate your reference stars (e.g., Polaris, Big Dipper, or Octans).

3. Rotate and adjust the mount until the constellation pattern matches the reticle.

4. Use your mount’s azimuth and altitude controls to place Polaris (or Octans stars) precisely in the centre of the crosshairs.

No electronic aids, no guesswork—just accurate visual alignment.
