Newtonian base for Starlight Feather Touch focuser FTF2008, FTF2015... Suitable for 481 mm diameter tubes.
♦ CNC Bases for 2" Starlight Feather Touch Focusers
♦ The contact surface optimally adapts to the tube surface thanks to its stepped design, it is not possible to tip over
♦ The base is suitable for telescope tubes with a diameter of 481 mm, for example many 16" Newtonian telescopes such as TS ONTC16
♦ The focuser is attached with four grub screws.
♦ Distance between the holes for fixing the telescope: 100 mm along and 100 mm along the tube
Newtonian base for Starlight FTF20.. Focusers
The base fits Newtonian telescopes with 481mm diameter tubes. Due to a special shape of the contact surface, the base always adapts optimally to the curvature of the tube. Tilt is not possible. The large contact surface also ensures stability and prevents the tube from deforming.
The base is fixed to the tube with M4 screws (not included).
We deliberately omitted the base toggle bolts because the base is used for carbon tubes. To tilt the base, you would need a metal plate between the carbon tube and the base so that the counterscrews don't pierce the carbon. In practice we have never had to tilt the base, as the focuser has always been very precisely aligned with the secondary mirror.
