Stellarvue optics are fully multi-coated to increase light transmission and contrast. The telescope is internally baffled and treated with an ultra flat black interior. Stellarvue designs and handcrafts the finest refractor telescopes.
The tube, dew shield, and fittings are precision machined. All aluminum parts are black anodized with a polished, high gloss finish. The dew shield can also serve as a glare shade during the day.
Internal tube treatment:
The inside of the tube assembly is painted "ultra flat black" and is fully baffled to eliminate reflection. The focuser is ultra flat black inside to reduce drawtube reflections.
Dual speed Crayford focuser with precision bearings:
The 2" Crayford focuser uses a compression ring and has three thumb screws to secure accessories and cameras firmly in place.
A compression ring 1.25" adapter with 2" filter thread is also provided: The focuser has three focusing knobs, one on the left and two on the right. The single knob on the left and a larger knob on the right provide coarse focusing. On the right side is a second, slightly smaller, brass colored fine focus knob. This fine focus knob has an 11-1 rotation reducer, allowing for extremely fine focusing.
The reducer in the Stellarvue focuser uses a hardened stainless shaft and precision ball bearings. It has greater longevity than some competitive dual speed focusers. A tension adjustment set screw is positioned under the focuser and a thumb screw allows for locking the focuser when engaged in astrophotography. The drawtube is inscribed with a millimeter scale on top.
Two 5 mm threaded holes on top of the focuser allow for the attachment of two separate finder scopes. To rotate the focuser, simply loosen the rotation lock knob on top.
Vixen mounting rail:
This telescope has two Stellarvue rings with Losmandy rails, the L-shaped mounting base will attach directly to the TP6 (Losmandy sized) plate with two screws to the existing rail.
