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.

Product QuestionsQuestion by: doug248 on Dec 13, 2014 3:38:48 AMYes, the Celestron 8SE has a "V" style dovetail on the bottom and the saddle on the iEQ45 Pro mount will accept both D and V style dovetails. The 8SE optical tube is ~13 lbs, and the mount comes with enough counterweights to balance that weight.Answer by: Chris (Admin) on Dec 14, 2014 5:35:22 AMQuestion by: TURKI alamri on Jan 16, 2016 2:57:00 AMThis particular mount cannot be use in Alt-Az mode. The model you may be referring to is the iOptron IEQ45-AZ. Here is a link to it's product page on our website.
That package will come with everything to use in Alt-Az mode.Answer by: Jonathan Cheek (Admin) on Jan 18, 2016 6:13:00 PMThe 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.Question by: Jim on Oct 6, 2015 10:45:00 AMWhat the reviewer meant is that, unlike some competing mounts, the iEQ45 Pro mount does not have index marks to quickly get the mount into "polar home position." The user found it helpful to add his own index marks so that he could achieve polar alignment more quickly. The index marks are not totally necessary - many high end mounts from Software Bisque and Astro-Physics do not have them - but they can speed up setup.
The mounts we get new from iOptron come with the latest stable version of the firmware that the manufacturer loads on the hand controller. Occasionally, a newer version of the firmware comes out in between when the mount is delivered to OPT and when it is ordered by and shipped to a customer. In these times, the manufacturer's website will have the newer firmware available for download via the included RS-232 serial cable. You may need a USB-RS-232 adapter for some computers.Answer by: Chris Hendren (Admin) on Oct 6, 2015 2:47:00 PMDoes the payload of an equatorial mount (like the iOptron iEQ45) include the counterweights or is the payload for observing equipment only, not counting counterweights?Question by: Eldon Byland on Aug 18, 2015 1:00:00 AMWill 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?Question by: Melvin on Mar 15, 2015 9:29:00 PMThe tube weight for the 12" scope without rings or dovetail is 40.5 lbs. Once you add the accessories, the coma corrector and the finderscope, you are past the 45 lb carrying capacity for the iEQ45 Pro mount. The CEM60 would be a better choice for this scope.Answer by: Chris Hendren on Mar 17, 2015 4:22:00 PM
