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, adjustable brightness and blink-rate 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. It's 6-arc-minute accuracy over any eye position allows you to pin-point objects -- even with high-power eyepieces in the telescope. 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. Mounting hardware included.
This Starbeam model has a dovetail bar and mounting bracket that fits the rear cell of any 8" or larger SCT. The bar and bracket are also sold separately so any Starbeam owner can adapt the uniquely accurate, large aperture 1x finder to SCT models.
Base also accepts Tele Vue-60 as a quick-release super-finder.

I've got lots or red dot finders on many different scopes. Most work just fine, but they have some issues with eye placement, ease of use, and transparency of the glass surfaces. I decided to splurge on the much more expensive Televue Starbeam. Wow what a difference. Wide, clear field of view from most any distance. Leave it to Televue to perfect the simple red dot finder. Should have bought this first. Nice construction, flawless performance.
