About the TeleVue Starbeam Finder - SCT...
Designed with a dovetail bar and mounting bracket that fits the rear cell of any 8" or larger SCT, this exquisitely designed red dot reflex finder is not only functional, but a true work of physics genius and optical art. For anyone who has ever used a illuminated concentric circle finder or red dot finder, there is a point where it is difficult - if not impossible - to see the projected image. Not so with the Televue Star Beam! Let''s take a look at the man behind the curtain...
Located behind the flip mirror is an illuminator. This is the projector which produces the red finder "star" which is fully user adjustable for color, brightness and size. At the business end of the Televue Star Beam Finder, a 39mm aperture high quality concave lens collects starlight and acts as a beamsplitter - collimating and combining the background view and the 10 arc minute diameter projected red star. The highly polished first lens surface acts as a mirror and a compensating curve designed into the second lens surface provides the normal sky background view. Both surfaces are multi-coated to eliminate double images. This means no matter what angle you view from, the projected red "star" stays stationary - from two inches to two feet. The Televue StarBeam Finderscope offers 6-arc-minute accuracy - regardless of eye position. No more head turning, eye blinking and moving around to find the red alignment image and guessing with high power eyepieces... It''s there!
The light-weight pivoting first surface flip mirror allows the TeleVue Starbeam Finder to be used either straight-through, as a right angle finder or whatever angle the user needs. The bar (SBB-1002) and bracket are also sold separately so any Starbeam owner can adapt the uniquely accurate, large aperture 1x finder to SCT models. Bracket (SAB-1001) also accepts NEW Televue-60, so that you can use it as a quick-release super-finder. Just slide the Televue Star Beam Finderscope on the base rail, secure with the knurled knob, and align to your telescope''s optics with the azimuth and altitude adjustment knobs. Elegance meets ease...
Nothing says quality like the Televue StarBeam Finder. The Starbeam is custom machined completely from aluminum and then black anodized, even down to the "push-pull" thumb screws. No tools are required to align Starbeam with your telescope and all mounting hardware is included. Doesn''t your telescope deserve the Televue Star Beam?
