iOptron iEQ45-AZ Dual Equatorial/Alt-Azimuth GoTo Mount W/ Tri Pier - DISCONTINUED

The iOptron iEQ45-AZ Pro Dual Equatorial/Alt-Azimuth GoTo Mount with Tri Pier 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.

This version of the iEQ45 includes the components needed to easily convert the iEQ45 from an equatorial to an alt-azimuth mount. The #8050 AZ Base connects to a tripod or pier, so you could run your scope in alt-azimuth mode one night and in equatorial the next, depending on whether you were imaging or doing some quick (or not so quick) visual work. You will also receive a secondary saddle and shaft, #8055, which allows you to ride two telescopes side by side in Alt-AZ mode.

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.

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 degrees 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.

Polar align your iEQ45 with help from the included AccuAlign dark field illumination polar scope. iOptron's AccuAlign 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.

After a long wait true disappointment

After nearly a 3 month back order wait the mount finally arrived. It is easy to set up and polar align, easy to set zero position, however that is where the functionality ends. The Gps function seems to function intermittently and looses date and time constantly, it likes to reset the utc time numbers which by the way needs to be set to -300 for East Coast, not sure why, Our celestrons use 420. Using a 23.8lb Astrograph the mount struggles on max slew, sad for a 45lb limit mount, once the struggle starts which sounds like a clutch issue, you have to manually stop the slew and then re-set zero position then do the star align all over. The slip is less apparent on 512x but the tracking suffers from the slip and after 3-5min the target is out of the eyepiece. The mount is useless for astrophotography and not much better for visual. IoPtron is insistent it needs to put upgraded boards in for motor torque, why would a brand new mount need extra torque boards to handle half a load? Stay away from Ioptron mounts, it is sad when 2 mounts with half the load weight rating AVX & CG5 do a better job with the Astrograph. Should IoPtron get this rectified I will right an updated review, but for now the dissapointment and trouble make this company a no go for me!
