♦ Distance of the 4x M3 threads (female) from the center: 36 mm (90° angle to each other)

♦ Eyepiece side connection: 2" and 1.25" receptacle with compression ring.

♦ Minimal height to the support: 74 mm

♦ Draw tube travel: 50 mm

♦ Bearing via stainless steel rail - absolutely free from twisting

♦ Central locking of the draw tube, guaranteed without tilting

TS-Optics 2" MONORAIL Focuser with flat Support
The TS Monorail focuser is an improvement of the time-tested Crayford focusers. Our goal was to offer a focuser for highest loads, like heavy CCD cameras, with very high precision at the same time. We exactly succeeded in this with the Monorail focusers.

At the telescope side, the MonorailFL has a flat support area with 4x M3 threads (female) at a distance of 36 mm (each) to the center. With this connector you can easily attach the focuser to flat surfaces. An additional ring with corresponding through holes allows safe locking, for example if the support surface is made of wood. Four M3 screws with 7 mm thread length are supplied.

The advantages of the TS Monorail focusers at a glance:

♦ higher load capacity than with normal Crayford focusers - instead of small ball bearings, a massive stainless steel rail, which is laterally clamped, is used.
♦ more precise guiding of the draw tube and no more tilting when locking
♦ smooth motion and finest adjustment even at loads of up to 4 kg
♦ 1:10 dual speed for accurate focusing
♦ Motor focus can be retrofitted
