TS-Optics 2" and M48 Non-Rotating Helical Focuser and Variable Extender

You are looking for a precise focuser which can easily be attached to your telescope, or a precise variable extension for photography and visual observing? If so, the TSHeli2 is the right one for you.
 

Application areas of the TSHeli2:

♦ High-precision focusing of telescopes with relatively coarse focusing like Schmidt-Cassegrain telescopes or manual Maksutov telephoto lenses.
♦ Variable extender with M48 connection at both ends for exact adjustement of the distance.
♦ Perfectly suitable for photography, the distance is perfectly maintained by two locking screws.
♦ The accessories stay exactly where you want them to be. Camera and eyepiece do not rotate. The inner tube moves up and down with millimetre precision, simply by turning the knurled outer part.
 

Advantages and features of the TSHeli2:

♦ Camera or star diagonal do not rotate when the focuser is adjusted.
♦ Easy adaption to the telescope or the camera by M48x0.75 (2") filter thread.
♦ The TSHeli2 can be inserted directly into a 2" focuser. -- Can also be used as variable M48 extension from 53 mm to 92 mm.
♦ Two locking screws allow secure fixing of the focus position.
