Avalon X-Guider - Tangent Mount Assembly for Guide Telescopes

Avalon X-Guider - Tangent Mount Assembly for Guide Telescopes

It is extremely compact and innovative for found the guide star in astrophotography, which comes from a long experience in the field of astronomical photography.


Its main characteristic is that while having a load capacity of more than 6 kg is very light, with a mechanical simple, robust, without slack and above all it has the ability to make adjustments with one hand through two convenient knobs, important when one must act in uncomfortable condition.

Once the final position is found, it is possible to lock the elevation through two knobs and since the azimuth is ensured by the pressure of a very strong spring, the system is totally free from play and mechanical bending, absolutely essential in a system with autoguider. Another important aspect is the low profile that allows you to maintain a low center of gravity resulting in less weight to balance. The system is equipped with a standard GP dovetail for mounting the guide telescope and a second removable flange GP, through which a fast and efficient mounting in parallel on a standard bar GP at the side that superimposed on the main telescope is possible.

The Avalon X-Guider is a high precision and play-free guidescope aligning accessory. Unlike conventional guidescope rings, which rely on pushing screws on to the body of the tube, the Avalon X-Guider features a dovetail mounting system (GP 45 mm size) for a quick-release attachment/detachment of the guide scope on the main telescope.

The X-Guider features a very compact body, an innovative design and a beautiful look. All aluminum parts are CNC machined. All screw knobs, designed by Avalon Instruments, have a special ergonomic design and are made with a special polymer. It features also a very hard anti-scratch anodized surface finish with CNC engraved characters.

The Avalon X-Guider is used to easily locate guide stars during astroimaging sessions and it has been designed after much experience in deepsky astroimaging.

One of the most innovational aspects of the Avalon X-Guider is the ratio between the high loading capacity up to 5 kg (12 lbs), and the device weight, of less than 600 g. This is a very useful characteristic for portability as well as putting significantly less load on your mount. The X-Guider mechanics are very simple, sturdy, totally free from backlash in azimuth and free from flexure in typical working situations.
