♦ Maximum load of the focuser is 6 kg, with full precision and smoothness.
♦ The 1:10 transmission is made out of V2A sttel in professional quality.
♦ The focuser offers compression rings for 3", 2″ and 1,25″ accessories.
♦ The drawtube accepts 3" accessoiries on its complete length, no bottelneck blocks the passage.
♦ The drawtube was provided with an antireflex thread.
♦ In addition, there is an M82 auxiliary thread on the drawtube to be able to permanently install M82 filters, for example.

Motorfocus - for many astrophotograpers a MUST-HAVE

The USB_FOCUS_SET and the USB_FOCUS_SET-H can easily be adapted to the UNCN3 focuser by using the BR-UNCN3.
