The iOptron iEQ45 series of mounts is aimed at the astro-imaging enthusiast. It's  has a light-weight head with a high capacity to weight ratio, and the unique AccuAlign TM GPS driven polar alignment system makes for quick, easy setup in the field.
What's new on the iEQ45 PRO? The new iEQ45 PRO features new even more advanced electronics, and mechanical components, derived from the ground-breaking CEM60 design. Compabined with the existing features, the iEQ45 PRO is now a class leader in this class of equatorial mounts.

Price and availability: We will have more information on the new iEQ45 PRO price and availability soon and will add it to this webpage. In the meantime please click on the "notify when in stock" button to get an automatic update when the product is ready to ship.
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.

  • All officially imported iOptron products sold by official distributor Altair Astro (and our European partner companies) have a unique serial number for warranty purposes, to help us support you.
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.

Warranty note: We have recently become aware of UK companies and inviduals purporting to offer "hypertune" modifications, servicing and repair for iOptron products. There is no company in the UK authorised to repair iOptron products other than Altair Astro (official iOptron agents). We have had mounts back in for servicing after they have been modified with incorrect parts, lubrication, and internal adjustments. We will do our best to help reverse these changes at a reasonable price to get you going again. Any work which is not performed by Altair Astro will invalidate your warranty. If you require servicing or spares from Altair Astro, please contact us, or ask your official dealer to contact us on your behalf.
