The high-quality 2" Crayford focuser
The 2" Crayford focuser with 1:10 speed reduction is included. Accessories are evenly clamped with a brass compresssion ring. The 1.25" reducer is equipped with a brass ring, too. The focuser will not wobble even when used with heavy cameras. With the 1:10 speed reduction, precise focusing is possible. Point-shaped stars over the whole field are the result.
