iOptron iEQ45 Pro Computerized Equatorial Mount

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 the AccuAligning Polar Scope

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.

Customer Reviews 1 item(s)

High quality mount.
I've had this mount on the sky twice and recorded excellent 5-minute exposures using closed loop (ASCOM and PHD2) guiding. Operation is smooth and quiet. My telescope and guide scope weigh 32 pounds, which the iEQ45 Pro handles easily. Above about half maximum payload a counter weight extension is needed. The polar alignment works extremely well. The combination Vixen and Losmandy attachment is very secure and easy to use. It took an evening to update the firmware in large part due to the English made in China in the documentation that takes some work to decipher. North celestial pole is not marked on the mount therefore needs to be determined. I used iterative setting of the pole position and one star align to arrive at the NCP location to mark on the mount. With this done and with the easy to use polar scope, accurate setup even for astrophotography should go quite quickly.

Questions & Answers

Product Questions

Will this mount work with a celestial 8 se Thanks
can i convert this mount to an Alt Azm mount ? if yes whats the proper parts i need?
What's the difference between an iEQ45E & an iEQ45 Pro?
The single reviewer of this mount on your website here said that one drawback of the mount was that the North celestial pole was not marked on the mount. I don't understand what he meant by that, or why it's not marked on the mount, and/or how he was able to locate it and mark it on the mount. Can you help me understand all that? thanks.

Also, does this mount come updated with the latest software update? That was another comment of the reviewer.
Does the payload of an equatorial mount (like the iOptron iEQ45) include the counterweights or is the payload for observing equipment only, not counting counterweights?
Will this mount handle your TPO 12" f/4 Imaging Newtonian OTA? If so, does it need a Counterweight Shaft Extension Bar or extra 5kg Counterweight or both?
Does the mount have ST4 input for auto guiding?
