The ZEQ25-GT is a GOTO equatorial mount from iOptron designed for imaging and visual observing. It offers one of the most sophisticated electronic/mechanical packages on the market today in a smaller sized equatorial mount, with all the features you need to start imaging in the field quickly and easily.
With a payload of 11.3kg it sits between the IEQ30 and the SmartEQ PRO in carrying capacity and size, with a unique and innovative Centre-Balanced or CEM design.

Here are some You Tube videos of the iOptron ZEQ25-GT in action, which demonstrate the mount's operation.
The new iOptron "Z" design mount puts the weight of the payload at the center of gravity allowing for greater natural stability. Given its payload capacity, this means the "Z" designed mount is unusually light-a nice benefit when setting up at a remote site. Other features include an adjustable counterweight bar to prevent obstruction with the tripod. And polar aligning is quick and accessible all the time since the polar scope is not blocked by the declination shaft this design is known as the CEM or Centre Balanced Equatorial Mount.
The ZEQ25-GT is equipped with the most advanced GOTONOVA® GOTO technology, making it one of the most powerful and accurate GOTO mounts available. Its database includes over 59,000 objects-its Go2Nova® Hand Controller is intuitive to use and its large 4-line LCD screen simplifies the process of setting telescopes and locating objects. The ZEQ25-GT - a new category of viewing and astrophotography.

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.
