TS 2" Dual-Speed Crayford Focuser for Refractor Telescopes
The Crayford focuser is well suited for observation and astrophotography with DSLR or astro cameras. We recommend the focuser for accessories up to approx. 2 kg. The focuser is also often bought for the self construction of refractor telescopes or for the improvement of existing telescopes.

The focuser is particularly suitable for many refractor telescopes from Skywatcher, Celestron and Orion. The connection adapter fits directly to the tube or into the reducer which is attached to the back of the tubes. Please measure the diameter before ordering. The tube (or the reduction adapter) must have an inner diameter of 86 mm to fit.

The 1:10 dual-speed micro-reduction significantly improves focusing. Particularly in astrophotography, sharper images are possible because the focus is precisely reached. But observation also becomes easier, as you know exactly when optimum sharpness has been achieved.

Attaching the focuser to the tube:
A telescope adapter with an outer diameter of 86 mm is also included in the scope of delivery of the focuser. In the adapter are three M4 threads at an angle of 120°. This allows you to attach the focuser to your refractor. Of course we can also make an individual adaptation for your telescope. We will be happy to advise you.
