The NEW AstroTrac TT320X
You can now capture great images of a huge variety of objects more quickly and easily than ever before with the new improved AstroTrac TT320X equatorial mount. Its the perfect match for easy to use DSLR cameras, providing an alternative to complex, heavy equipment and long learning curves.
The TT320X has the following new features:
Solar and lunar tracking rates as standard
New drive mechanics - more accurate than the TT320
Weighs just 1.1 kg (2.4 lb) - 0.25 kg (0.5 lb) lighter than the TT320
New longer polar scope arm - easier to polar align
Increased 15 kg (33 lb)load capacity - 5 kg (11 lb) more than the TT320

Super Accurate
The entirely redesigned drive mechanics give the TT320X unguided tracking accuracy which has to be seen to be believed.
You can easily capture pin sharp stars at 500 mm or more focal length. The only other mounts which can match the unguided tracking accuracy of the TT320X cost many thousands more.

Most DSLR camera exposures are around 5 minutes or less. The TT320X has typical unguided tracking error of around 5 arcseconds peak-to-peak or better over a 5 minute period.
Each TT320X 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 trailed stars.
Ultra Portable
The TT320X 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.

NEW - Lower Weight
The ultra portable TT320X weighs only 1.1 kg (2.4 lb). Extensive CNC light weighting of the major components makes the TT320X 0.25 kg (0.5 lb) lighter than the TT320. If you are planning your next trip - you'll be hoping to carry the minimum equipment and get the maximum results.
NEW - Increased Load Capacity
Despite its minimal weight, the TT320X can easily carry 15 kg (33 lb) of cameras, lenses and telescopes.
Power Supply
You don't need to worry about lumping large power supplies with you either. The TT320X 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.
NEW - Solar and Lunar Tracking as Standard
Coronado PST and AstroTrac
The TT320X comes with 2 hours sidereal, solar and lunar rate tracking as standard, opening up an even wider range of targets to you.
If hydrogen alpha is your thing, the TT320X is the perfect companion to popular solar scopes like the Coronado PST.
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.
Make sure you select a sufficiently rigid mounting to handle the weight of your equipment without flexing during an exposure.
Quick to Setup, Easy to Use

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.
It can be suprising how you can can significantly increase the amount of astro photography you do by making the most of small windows in the weather.
NEW - Easier Polar Alignment
New Longer Polar Scope Arm
The TT320X's new polar scope arm is 40 mm longer than the TT320's making it easier to view through the polar scope.

Gorgeous Design and Finish
Every effort has been made to make the TT320X beautiful as well as functional. The aluminium is hand brushed by a skilled craftsman and then anodised by a Rolls Royce approved company to lock in the beautiful finish and provide scratch and weather resistant for use in the field.
Patent Pending Technology
The TT320X 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 centres.
The majority of components are made from aerospace grade 6082 T6 aluminium 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 uses two high performance microprocessors running at 20 and 16 million instructions per second.
At the heart of the TT320X 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 minimise 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 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.
