About this product

Model:  Astrotrac_TW3100

The stylish TW3100 sets a new standard for high strength compact equatorial wedges. Carrying up to fifteen times its own weight, with the TW3100 you can now realise the full potential of your TT320X with larger lenses and telescopes.

Rock Solid

When you've got clear skies, perfect framing, and pin-sharp focus, the last thing you need is flexure spoiling your image. The unique patent pending design of the TW3100 wedge provides a rigid platform for your imaging equipment whilst retaining true portability.

The AstroTrac TT320X is quickly and easily mounted to the TW3100 with three 4 mm stainless steel mounting screws supplied with the wedge.

Tripod and Pier Compatible

The TW3100 is perfectly matched to the AstroTrac Pier and can also be used with any photo tripod equipped with a standard 3/8" photo thread. Contact us to check compatibility with your equipment.

Easy Polar Alignment

Specially made stainless steel adjustment and locking knobs with fine pitch aerospace threads give smooth and precise altitude and azimuth adjustment even under large load.

Compact and lightweight

The TW3100 can be easily carried in your airline luggage thanks to its compact size. Get your holiday or vacation off to a great start by avoiding costly excess baggage charges. Weighing just 2.2 lb (1 kg), you'll be pleasantly suprised by how little space and baggage allowance your TW3100 takes up.

Worldwide Operation

With a latitude range of more than 90 degrees you can use the TW3100 from pole to equator. The easy-to-read latitude scale has 15 degree coarse increments and infinite fine adjustment via the conveniently located altitude adjustment knob at the rear.

The built in bubble level makes precise leveling easy, saving you time during polar alignment.

Beautifully Engineered

The silky smooth anodised aerospace alloy is perfectly complimented by the unique polished AstroTrac stainless steel knobs. The overall experience is as pleasing to the touch as it is to the eye, designed to give you many years of corrosion free reliability and handling pleasure.

The TW3100 is manufactured with loving care by highly skilled engineers at AstroTrac's factory in the UK using state-of-the-art CNC machinery.

Small is beautiful

The astrotrac wedge is small and solid. It fits on my Manfrotto tripod and the astrotrac is attached to it with three screws. I upgraded to the wedge when I started using a small telescope on the astrotrac. Once the wedge is adjusted and set in position it is very firm.

The azimuth has two screws to adjust it (left and right) and then three screws to lock down the "turntable" part of the wedge. The altitude has one screw and relies on the weight of the equipment to move the wedge down as you loosen it. The altitude is locked by a plastic lever from one side... this has the effect of shifting the azimuth as you tighten it, so final adjustment to achieve polar alignment tends to be an iterative process. The metal knobs get cold in Winter and can be hard to grip with frozen fingers.

The wedge is small, solid and very well made. Very glad I bought it.
