The new iEQ45 2013 version with Field Tripod.
Initially, the iEQ45 v1 & 2 mount was aimed at the imaging enthusiast. Light-weight, high capacity, and fast easy setup with GPS polar alignment assistance made it a great mount for visual observers too - but it was always purely an equatorial mount until now. 
What's new? The new iEQ45 2013 retains all these features, however, it can be used with an optional Azimuth Base Adapter (#8050) in Alt-Azimuth Mode for visual observing or planetary webcam imaging and astro-video. This makes it extremely versatile and convenient because in Alt-Azimuth Mode, polar alignment is not necessary. That makes it even quicker and easier to start an observing session, using the accurate GOTO system to find thousands of objects in the night sky, and keeing them in the field of view at high power for many hours.
Equatorial Mode and imaging:  Equatorial Mode is of course best for long exposure imaging because there is no rotation of the star-field over time. In Equatorial Mode, the iEQ45-2013 remains a very quick mount to set up in the field, because it has an very accurate polar alignment scope, with built-in GPS 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.
Converting from Equatorial-Mode to Alt-Azimuth Mode: You can convert your iEQ45-2013 EQ mount to Alt-Azimuth Mode with the optional AZ Base (product code #8050) if you prefer visual observing this way, and back Equatorial Mode again for example if you want to take long exposure deep-sky images.
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. 
Optional light weight field pier: The lightweight, yet extremely rigid iOptron portable pier is also available separately. 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.
Weight and portability: The iEQ45 is the lightest mount in it's price range, and it's very easy to carry. The head weight (heaviest component) is only 9.7kg! The iEQ45 weighs less than half other mounts with the same carrying capacity. This is probably the best ratio on the market for a mount in this price range. (Please note, the stated capacity does not 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).
PC remote software control: Aside from the GPS and Polar Alignment asistance features, PC control is possible using planetarium software. For accurate autoguiding, an ST4 port is provided. The mount can record Periodic Error Correction data from 3rd party software to play it back and improve tracking accuracy even more. The brightness adjustable multi-line display hand control module is extremely easy-to-use, and contains an enormous 130,000 object database.
The iEQ45 is one of the most anticipated products, particulary amongst the astro-imaging community, and customers have captured some excellent long exposure 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.
