AstroTrac TT320X-AG 

  • Included AstroTrac PolarScope

With the TT320X-AG you can take longer exposures at longer focal lengths allowing you to create brighter, less noisy images. Fully compatible with the AstroTrac Polar Scope, Pier, Wedge and Head.

Get pin sharps stars at longer focal lengths with the TT320X-AG's right ascension autoguiding capability. Compatible with popular ST-4 autoguiders such as the SBIG SG-4, Orion Starshoot, LVI SmartGuider, and with popular autoguiding software such as MaximDL and PhD. 
* Autoguiding requires an additional cable which you need to order seperately.

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 trailin

Ultra Portable

The TT320X-AG is remarkably compact - its roughly as long and as wide as your forearm. Put it in your suitcase or your computer bag and take it with you whenever you travel.

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.

Quick to Setup, Easy to Use

You can setup the TT320X-AG and start imaging in minutes. Step out into your garden and take advantage of short gaps in the cloud.
