Starlight Instruments 3" Feather Touch Focuser with Micro Reduction - 63.5mm Adjustment Range

This focuser is for all star lovers who need a focuser larger than 2" but still want it to be compact.

Above all, the extract offers better lighting, which is necessary for working with larger chips. The adjustment range is pretty universal at 63mm - the focuser can be used in Newtonian telescopes because the focuser tube doesn't protrude too far into the tube.

The advantages of Starlight Feather-Touch focusers:

♦ 100% correct position of the image plane - no tilt

♦ Good illumination even for large sensors

♦ Micro reduction for more precise focus

♦ Free adaptation to different types of telescopes (connection adapter see recommended accessories)

♦ Brake for free resistance adjustment - eliminates the need for clamping

♦ Regulation of the extension tube by rack and pinion decoupled from the bearing

♦ Brass toothed racks and hardened stainless steel toothed wheels ensure a responsive fit even under maximum loads

♦ Long life: the Feather Touch focuser is for life

♦ Wide range of accessories and connection adapters, as well as the possibility of motorization

Note: The telescope connection adapter is not included in the scope of supply.

Eyepiece and camera-side adapters are listed under "Adapters."
