| One of
the features of the T2 diagonals - be it prisms or mirrors - is the large free
aperture and the flexibility to directly adapt onto almost any telescope system
- without the bottleneck of a 1¼" barrel size which may cause vignetting
in long focal length 1¼" eyepieces or when working with a bino viewer on
top of the diagonal. Exactly this is the reason why we offer the body of all
our T2 System diagonals without adaptors ( Of course - it can be adapted just
alike all the other diagonals by using our standard T2 / 1¼" nose piece
#14, but then some of it's beauty [clear aperture !!] is left
unused..). The telescope side of all our T2 diagonals accepts an entire armada of Baader-adapters, be it for 1¼" or 2" focusers, be it for a Celestron OTA 2" thread or an original M44 Zeiss thread, be it for Vixen OTA's or Russian MAK's - or whatsoever ( all to be found on our Astro T2 System drawing ). On the eyepiece side many people put only our quick change ring #6, in order to mount the Mark V binocular viewer instead of an eyepiece, in order to achieve the shortest possible backfocus distance between telescope and binocular viewer - alternatively mount the 1¼" CLICKLOCK- eyepiece clamp, for the quickest clamping action in the industry. Our three T2 diagonals all were based on the design of the famous Zeiss M44 Star Diagonal which featured the same versatillity with the body itself being adaptable onto almost everything within the Zeiss M44 system of telescope accessories. We try to provide the same versatility within our brandmarked ASTRO T2 System™. |
