About the Antares Collimatable Dielectric SCT Mirror Diagonal - 2"...
The Antares Collimatable Dielectric Mirror Diagonal features threaded, chrome plated brass barrels and fully coated optical components. If you have a Schmidt-Cassegrain (SCT) or refractor telescope with 2" capacity and are using regular or enhanced aluminum coatings with your diagonal, your transmission will be between 88% and 92% over the visual spectrum. You''re throwing light away! And if you are using a 1.25" diagonal with a 2" format, you''re missing out on your telescope''s widefield performance.
All Antares Collimatable Dielectric Mirror Diagonals feature enhanced silver coatings with a visual light efficiency of over 98%. Your image is conveniently delivered with virtually no light loss at all. There are five models available for both straight 2" bores and for standard 50mm thread Schmidt-Cassegrain telescopes. All feature 6-layer enhanced silver coatings with overcoating protection and include 1.25" adapter.
2MDC: Collimatable diagonal for 2" straight bores. Many refractor owners are shocked to learn that their extruded aluminum tubes are not straight! With a collimatable diagonal the light beam can be better directed into the eyepiece. Barrel threaded for 2" filters.
2MDSC: Collimatable diagonal for standard SCT thread. The ultra-short input profile on this diagonal will allow swing-through on most fork mounted versions.
