Description

TS 2" Crayford focuser with micro reduction for refractor telescopes

The Crayford focuser is well suited for observation and astrophotography with DSLRs or astrocams. We recommend the extension for accessories up to about 2 kg. The focuser is also often purchased for self-building refracting telescopes or to upgrade existing telescopes.

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

The 1:10 micro reduction significantly improves the sharpness setting. Especially in astrophotography, sharper images are possible because the point of focus is reached exactly. But observation is also easier, you know exactly when the optimum sharpness has been reached.

Attaching the focuser to the tube:

The scope of supply of the focuser also includes a telescope adapter with an outer diameter of 86 mm. The adapter has three M4 threads at an angle of 120°. This allows you to connect the focuser to your refractor. Of course, we can also make an individual adaptation to your telescope. We will be happy to advise you.
