Economical Mounts for Everyone

Featured Mounts

That's Right. There is a new iEQ45 Mount!

The iEQ45-AZ German equatorial-altazimuth GOTO mount is the latest development of iOptron’s premium equatorial mount, the iEQ45. It offers superb astro-imaging capability and portable visual astronomy. With the ability to change from altazimuth mode to equatorial mode you have a product with high performance in both positions.

The iEQ45-AZ mount offers the next generation GOTO technology from iOptron —not to mention built-in 32-bit GPS. With a payload of 45 lbs. for EQ mode and 90 lbs for AA mode (dual mounting) – it comes standard with a calibrated dark field illumination polar scope and a rigid portable pier. It also fits both Vixen and Losmandy-type mounting plates. Its lighter weight (only 25 lbs.) makes it much easier to carry.

                                                                              Does not include telescope and Power Weight.
