When the Clear aperture is large it needs to be well Baffle to avoid off Axis reflections. If you see them in your bino baffling is lacking.

Whether you have a Dob, Refractor or SCT this is the binoviewer for you. As you will see below nothing even comes close for this price.

These binoviewers are equal to or lighter then any other binoviewers on the market, They have more aperture then any binoviewer costing under $900, This means you can use any eyepieces you wish just like any other large prism binoviewer without the annoying vignette you get with binoviewer of small prism size. They have a OP/CA ratio that gives them the same FIA as the largest prism binoviewers on the market costing 3x plus.

This is true in any scope with an optical system from f4 - f10. In fact there is only 2 Prism based binoviewers that will give you ANY diameter of FIA spot in an f4.5 system is (This is not using and Optical Corrector in the system) and they are Baader 28mm and the new BN 25mm dielectric.
