Starbeam - For Tele Vue Scopes - With Flip MirrorStarbeam's unique flip mirror feature provides comfort and flexibility for viewing at any angle from straight through to 90?. Viewed straight through you see the natural sky with a 10 arc-minute (1/3 Moon diameter) red-star showing your scope's position. When your scope is pointed high flip the mirror into position for more comfortable viewing. Viewed this way the sky orientation matches a refractor or SCT's image. The size color and adjustable brightness of the red-star makes it easy to see against any twilight to dark sky background. With its 39mm aperture the projected image is easily seen any distance behind Starbeam whether 2 inches or 2 feet! The finely made glass lens acts as a beamsplitter to combine the natural sky background with the superimposed red pointing star. The first lens surface acts as a collimating mirror so the red-star stays stationary against the sky background regardless of how it is viewed. A compensating curve is designed into the second lens surface to provide the normal sky background view and is multi-coated to eliminate double images. Elegant in design and form 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. Two base channels are available one for Tele Vue telescopes (except Ranger) and one for scopes of 4 or larger tube diameter. Mounting hardware included.
