HFR3 Focuser/Rotator (Soon)

 

The Hercules Telescopes Focuser/Rotator is a masterpiece.  
 
With it's sleek and perfectly cylindrical design, it can fit where space is limited or in the middle of a prime focus telescope like our HTP500.  It's Rigidity and high precision without backlash make the HF3 Focuser/Rotator a perfect choice for an high quality image train.
 
The linearity movement is made using precision guide rails that stay perfectly aligned even at outermost position with lot of weight. Precision spring loaded gear are used to make the rotation with high precision cross roller cylindrical bearing.
HF3 is design so that a 3 inches corrector can fit inside and save space on your image train. 
Camera adaptor can be mounted on the focuser using 78 X 1mm thread or with 6 X M4 screws.
