New AZ & Pier Version of the iEQ45 2013
Includes #8050 AZ base, and #8033 42" field pier.
Initially, the iEQ45 mount was aimed at the imaging market. It's light head-weight, high capacity, plus fast easy setup make it a great mount for visual observers too - especially with the addition of the new Alt-Azimuth Mode.
In Alt-Azimuth mode, the iEQ45-AZ allows very rapid setup in the field for portable visual astronomy, planetary imaging with a webcam and of course video astronomy. Featuring a super-quick and simple alignment procedure - just like the hugely popular iOptron Minitower. However, no compromises have been made on the imaging capability of the mount, and it can still be used in Equatorial Mode for accurate long exposure imaging.
In Equatorial Mode the iEQ45-AZ is also very quick mount to set up and use in the field, because it has an extremely accurate polar alignment scope, working in concert with a 32-Channel GPS Module to improve polar alignment and GOTO accuracy. A display on the hand controller shows you where to place the pole star within the illuminated polar scope reticule for greater precision. With a combination of Alt-Azimuth Mode and Equatorial Mode, you have an extremely versatile product, which does it all.
Portable 42" field pier: The lightweight, yet extremely rigid iOptron portable pier is also included. The pier legs and steel tensioning rods fit into the hollow pier cylinder for easy transport as a single unit. The pier legs are adjustable for levelling. 
Pier diameter: 144mm (5.7”)
Pier transport height: 86cm (34”)
Standing height: 106cm (42”)
Leg length: 57cm (22.5”)
Net weight for transport with legs inside: 11.3kg
Payload: 60kg
Mounting a second telescope in AZ Mode: When operating in Alt-Azimuth Mode, you can even mount an additional telescope where the counterweight shaft usually goes. You can observe using two telescopes in this way! For example, a small wide-field refractor and a longer focal length scope can be used in tandem. To add a second scope in Alt-Azimuth Mode, simply remove the counterweight shaft and replace it with the optional iEQ45 Secondary Dovetail Saddle/Shaft (product code #8055). This includes a dovetail clamp which accepts both the wider 3.0" US-Style dovetail plate or the narrower 1.75" 1.75" Japanese format dovetail bars for maximum compatibility. 
Portability and light weight: The iEQ45 is one of the lightest mounts in it's price range, and it's very easy to carry, with the heaviest head component weighing only 9.7kg. The iEQ45 weighs less than half other mounts with similar carrying capacity. The payload vs. weight ratio is probably the best on the market for a mount in this price range. (Please note the stated capacity applies to one side. It doesn't include the supplied counterweights, which weigh an additional 22lb. If you load the mount to it's 45lb maximum capacity, you'll need to balance it with approx. 45lb counterweights, in which case the mount will be carrying about 90lb total weight).
More features than other mounts: Extra features make the iEQ45 stand out in the marketplace. The software based polar aligment routine was (at the time of writing) unique in the market. A dark field illuminated reticule that matches the angle display in the handset makes the mount very quick and easy to polar-align. Setup time and accuracy are further improved via a built in 32 channel GPS module. PC control is possible using planetarium software, and for fast, accurate autoguiding an ST4 port is provided. The heated, brightness adjustable multi-line display hand control module is extremely easy-to-use, and contains an enormous 130,000 object database. No other mount (at time of writing!) has all these features combined in this way, showing true innovation.
Reviews and accolades: The iEQ45 is one of the most anticipated products amongst the astro-imaging community and customers have captured some excellent images.

PLEASE NOTE: Do not be concerned if the box appears to have been opened. All mounts are removed from their boxes, and checked. We then apply a unique one-off, anti-tamper serial number to every product supported under our warranty. An image of the serial number is shown below. Legitimate iOptron products purchased from Offical EU Distributor Altair Astro UK and our official European partners all have this unique serial number either on the mount as shown, or inside the battery compartment. This entitles you to two years of warranty support from date of purchase, provided you can produce the original sales invoice with that serial number on it and the serial number on the product isn't showing signs of tampering.
