6" f/4 Imaging Newtonian telescope - for astro photography and rich field observation
fast and diffraction limited reflector system (f/4)
bright image by forced 94% mirror coatings
good field illumination by 63mm secondary mirror
robust mechanical system, no tilting/bending even under heavy camera load
improved Monorail focuser with 1:10 dual speed transmission - more stability compared with Crayford designs
ideal for travelling: tube length only 58 cm, weight only 5.3 kgs with rings/no finderscope.

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.
