Autoguiding requires an additional cable which you need toorderseperately.

Super Accurate Unguided Tracking

The phenomenalunguided tracking accuracyof 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 othermounts 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 around5 arcseconds peak-to-peak or betterover a 5 minute period.

Your TT320X-AG unit isindividually calibratedat 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.

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 andtake 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 easilycarry 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 youget 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 andstart imaging in minutes. Step out into your garden andtake advantage of short gaps in the cloud.

Gorgeous Design and Finish

Every effort has been made to make the TT320X-AG beautiful as well as functional. The aluminium is anodised to provide a scratch and weather resistant finish.

• The TT320X- AG comes with 2 hours sidereal, solar and lunar rate tracking as standard, opening up an even wider range of targets to you.

• The TT320X is easily polar aligned during the day for visual observation and photography of the Sun.

• Capture the beauty of the moon through its ever changing phases and majestic eclipses with the built in lunar tracking mode.

• Maximum enjoyment comes from taking the hassle out of carrying and setting up equipment, leaving you free to have fun and make the most of the moment.

• Every effort has been made to make the TT320X-AG beautiful as well as functional. The aluminum is hand brushed by a skilled craftsman and then anodized by a Rolls Royce approved company to lock in the beautiful finish and provide scratch and weather resistant for use in the field.

• The TT320X-AG is engineered to strict tolerances to give you optimum tracking accuracy and the reliability needed for years of use.

• All the components are machined at the Bristol UK based AstroTrac factory for optimum control over quality, using state of the art Haas CNC machining centers.

• The majority of components are made from aerospace-grade 6082 T6 aluminum for strength and light weight.

• All nuts, screws and hardware are made from corrosion resistant stainless steel.

• The printed circuit boards are robotically manufactured in the UK to the highest standards using environmentally friendly processes. The TT320X-AG uses two high performance microprocessors running at 20 and 16 million instructions per second.

• At the heart of the TT320X-AG is the precision motor and screw assembly which is manufactured in the US to AstroTrac\'s rigorous specification. The screw is an integral part of the motor to minimize periodic error.

• The screw is protected by a transparent screw guard, which is made from polycarbonate, a material commonly used for bullet proof glass and riot shields.

• Quality bearings are essential for smooth, accurate movement, so the TT320X-AG uses precision ball and needle roller bearings throughout.

• The AstroTrac\'s high load capacity and rigidity is achieved by a unique preload mechanism which takes up any play in the main bearings.
