A Starlight Feathertouch deluxe focuser upgrade for the Altair 8" and 6" RCs. This is an upgrade from the standard focuser for customers who want more stability, higher capacity and smoother focusing - specifically for imaging.
This package includes the following:
1) The 2" Feathertouch focuser with 1.5" drawtube for RC (not refractor).
2) Starlight Instruments adapter A20-271. This fits the telescope OTA directly, and is compatible with the extension rings.
3) 3x special non-standard thumbscrews which replace the grub screws in the A20-271 and allow easier rotation of the focuser. These extended thumbscrews are precisely machined from stainless steel, and make it easier to loosen the focuser-rotator to frame your image perfectly. Without the thembscrews, the standard focuser requires an allen key to loosen the grub screws for rotation. The extended thumbscrew solution make the focuser second-nature to rotate by "feel", and you don't have to worry about dropping tiny grub screws in the dark, never to be found again.
Automation: The Starlight Feathertouch focuser is not only a joy to use manually! It can also be driven by super-accurate stepper motors, using our Altair-Rigel USB nStep motor focuser system and the Starlight Feathertouch adapter bracket. With the USB autofocuser, precise manual focusing can be achieved using the hand controller for high power visual observation, or for imaging, you can fully automate your focuser via a USB connection and a PC using popular astronomy focusing programs via ASCOM. The high resolution stepper motors are capable of procise control with fractions of a millimetre. Please enquire further about automation options.
