The solution for telescopes with a stiff focusing
A wobbly image prevents precise focusing -
our smooth helical focuser makes this a thing of the past. An ideal tool for planetary photographers and observers who normally have only coarse focusing on their telescopes.
The advantages:
- eyepiece does not rotate with focuser
- focuser has a locking screw
- allows extremely fine adjustment - rotating through 360° only extends length by 10mm
- T2 thread allows photographic applications
