Product description

TS Helifoc - a short and precise focuser

A genuine helical focuser like this one works like a camera lens. When you turn the focus ring, neither the camera nor the eyepiece rotates; the only movement is inwards or outwards.

The advantage of a helical focuser is very fine focusing with high accuracy thanks to the large knurled ring and a low-pitch thread. This focuser stays exactly where you want it. The high accuracy and short design make it a very good addition to telescopes where the focusing is too imprecise.

The advantages at a glance:

  • The camera or diagonal mirrors do not rotate when the focuser is adjusted
  • Large focus range - 51 mm minimum height, 91 mm maximum height
  • Easy adaptation to the telescope and camera
  • Good solution for DIY telescopes
  • M48 thread connections on both sides (inside/outside), with all adapter options
  • Generous free aperture of 45 mm on the camera side and 47 mm on the telescope side
  • Also suitable as a variable M48 extension tube 51-91 mm for perfect distance determination
  • Two clamping screws to fix the focuser

Caution: The focuser is not designedfor heavy accessories, as it will tip over. The main accessories are small CCD cameras for planetary photography, 1.25" eyepieces and lightweight 2" eyepieces.

TS Optics is a brand of Teleskop-Service.
