With the TT320X-AG you can take longer exposures at longer focal lengths allowing you to create brighter, less noisy images.
Super Accurate Unguided Tracking
The phenomenal unguided tracking accuracy of the TT320X-AG has to be seen to be believed. You can easily capture pin sharp stars at 200 mm or more focal length. The only other mounts which can match the unguided tracking accuracy of the TT320X-AG cost many thousands more.
Most DSLR camera exposures are around 5 minutes or less. The TT320X-AG has typical unguided tracking error of around 5 arcseconds peak-to-peak or better over a 5 minute period.
Your TT320X-AG unit is individually calibrated at the factory, so the tracking rate is exactly right. You don't need to waste time measuring and adjusting the tracking rate to make sure its running at just the right speed to prevent your images trailing.

The ultra portable TT320X-AG weighs only 1 kg (2.2 lb). Despite its minimal weight, the TT320X-AG can easily carry 15 kg (33 lb) of cameras, lenses and telescopes. And you don't need to worry about lumping large power supplies with you either. The TT320X-AG draws minimal power, so you get around 10 hours tracking from a set of 8 AA cells. AA cells also have the advantage of being available just about anywhere in the world.
