Tele Vue Starbeam Finder - Tele Vue Telescopes
Tele Vue StarBeam Finder with Flip Mirror For Tele Vue Telescopes
Designed to be compatible with all Tele Vue telescopes (except the Ranger model) 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 Tele Vue Star Beam!
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. It has a 39 mm (1.54-inch) aperture high-quality concave lens which collects starlight and acts as a beam-splitter. It also collimates and combines 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 Tele Vue StarBeam Finderscope offers 6-arc-minute accuracy - regardless of eye position.
The light-weight pivoting first surface flip mirror allows the StarBeam to be used either straight-through, as a right angle finder or whatever angle the user needs. The removable black metal base channel fits the dovetail slot machined into the mounting ring of Tele Vue TV-85, TV-101, TV-102, and Tele Vue Renaissance-101 models. Screws thread through the base channel and into the telescope mounting ring, holding the base channel in place. Just slide the StarBeam Finderscope on the base rail, secure with the knurled knob, and align to your telescope's optics with the Azimuth and Altitude adjustment knobs.
The quality of the Tele Vue 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. All of the mounting hardware is included.

I ordered this in 2012 because I wanted the best red dot finder out there. I was suprised to discover that Televue has changed the build of the illuminator part without updating the product photo. It is now made totally of cheap plastic rather than metal in the older version. I am afraid to break it while turning it on and off. At this price point, it simply unacceptable.
