iOptron iEQ45 Pro Computerized Equatorial Mount with 48” Pier

The iOptron iEQ45 equatorial mount is the perfect instrument for beginning astrophotographers as well as visual amateur astronomers who would like a lightweight yet sturdy mount for their small to medium-sized telescope. With a weight capacity of 45 pounds, the iEQ45 Pro can handle a wide variety of refractor or Cassegrain-style telescopes with weight to spare, and with an actual weight of only 25 lb., it will be easy to set up, break down, and transport to your favorite observing location.

iEQ45 Equals Sophisticated Electronics

The electronics included with the iOptron iEQ45 Pro mount are those normally found on much more pricy models, including built-in 32 channel GPS, permanent periodic error correction (PEC), and an ST-4 autoguiding port that is capable of reverse guiding with auto-protection. Several tracking rates are available on the iEQ45 Pro, including Sidereal, Solar, Lunar, King (which compensates for the effect of refraction) & User. The User tracking rate can be set as required for your applications. The User Rate can be adjusted from 0.9900X to 1.0100X of sidereal speed.

GoTo Hand Controller with 580,000 Objects!

Control your iEQ45 Pro with the iOptron GOTONOVA hand controller with its amazingly huge 580,000 object database. The controller has an 8-line, 21 character LCD screen, and is heated so that it behaves consistently, even in cold weather…a thoughtful idea that is not commonly included on most computerized hand controllers. With this very smart controller you can slew (move) the telescope with nine different speeds. Zip across the sky at up to 5.83° per second to move from one object to another, or crawl along slowly to center the object in the field of view of your eyepiece or camera.

Includes a Polar Scope for Quick & Easy Alignment

Polar align your iEQ45 with help from the included AccuAlign dark field illumination polar scope. iOptron’s AccuAligning Polar Scope, together with its Quick Polar Alignment process and application, provides an accurate and fast polar alignment for an equatorial mount. The dark field illuminated dial makes the polar alignment simple and easy and it can be done just in minutes.

Achieve Premium Stability with 48” Pier!

Instead of a tripod, this version of the iEQ45 mount comes with a 48” aluminum alloy pier. The pier itself has a diameter of 5.7” is structurally reinforced with stainless steel rods that are adjustable, and the pier legs are made of steel and retract so that the pier will have a small footprint when not in use or during transport. The 48” Pier weighs just 25 pounds, making it just about as portable as a standard tripod.

Product Questions

My partner and I are going to purchase the telescope separately, the Ota is going to be purchased by me, so I need to know if a C8 HD Edge with the CGE bayonet or CG-5 bayonet is compatible with this mount. Thanks in advance!
