iOptron CEM40 Polar Scope Kit

iOptron's AccuAligning Dark Field Illuminated Polar Scope works with the CEM40 mount. The polar scope allows users to accurately align their mount.

The two sets of three concentric circles, clearly marked, help align the mount on Polaris in the Northern Hemisphere or Sigma Octantis in the Southern Hemisphere.

iOptron's polar scope is an excellent aide for precise tracking during long-duration observations or astrophotography sessions.

This kit includes the #3333 LED illuminator, a polar scope cover, and a polar scope adapter with four screws. These kit components ensure that you can accurately easily use the polar scope during dark observations, and you can protect your polar scope when it is not in use. The adapter allows for a secure connection between the CEM40 mount and the polar scope.

Once you insert the polar scope into the mount, adjust the eyepiece to bring the reticle dial into focus. The Polar Scope dial is divided into 12 hours along the angular direction with half- hour tics. There are 2 groups of 6 concentric circles marked from 36’ to 44’ and 60’ to 70’, respectively. The 36’ to 44’ concentric circles are used for polar alignment in the northern hemisphere using Polaris, while the 60’ to 70’ circles are used for polar alignment in the southern hemisphere using Sigma Octantis. Place Polaris or Sigma Octantis at the center of the polar scope dial when polar aligning, or if you have an iPhone, download the iOptron Polar Scope app in the Apple iTunes store for alignment assistance.
