TS-Optics MICRO-HELICAL Focuser with fine adjustment with 0.05 mm measuring scale

The micro-speed focuser provides precise focusing with almost any telescope. This is ideal for photography and observation of planets and lunar craters. At many telescopes, focusing is too coarse, so you will need a lot of luck for achieving the best focus point.

A further advantage is that the accessories, like a camera, do not rotate with the focuser. Therefore the orientation of the image remains unchanged.

Via the optional adapter T2i-T2i, the focuser can be easily attached to any male T2-thread, so the connection to your telescope becomes child´s play.

At the eyepiece/camera side, a male T2-thread (M42x0.75) is at your disposal. You can directly connect a CCD camera or your DSLR camera (via a T2-ring). Additionally, the 1.25" receptacle allows attaching of 1.25" accessories like eyepieces, C mount adapters, ...
 

The TSHeli1 for Schmidt-Cassegrain telescopes

Telescopes with primary mirror focusing often show "mirror shift". The image shifts or springs whenever one tries to focus with the primary mirror. Additionally, focusing is quite coarse, testing the photographers patience especially in planetary imaging.

The TSHeli1 also solves this problem through a very precise focusing without shift. For adapting the TSHeli1 to the 2" Schmidt-Cassegrain thread, you only need:

♦ T2i-T2i ... T2 reversion adapter - turn a male T2-thread into a female T2-thread
♦ TSSC-T2s ... adapter from T2 to the SC thread.

You can find both items in the "recommended accessories" section.
