As the CCD chips in our DSLR cameras get larger it is ever more important to have an unobstructed light path to prevent vignetting. The manufacturers of higher end scopes wisely put 2" eyepiece ports on them. Why then do we insist on putting a 1.5" bottleneck in the light path?

T-Rings have been around for decades, a legacy standard as outdated as 300 baud modems. They exist not because they are the best solution for imaging, but because they are the best solution for manufacturing. After all it's much easier to spin a standard thread on all adapters, regardless of telescope port size or camera brand. The T-Ring may be convenient but it is simply out of its league on a scope with a 2" eyepiece port.

Introducing "True-2" from Modern Photonics. As its name implies True-2 is a true 2" prime focus adapter that takes you directly from the camera bayonet to a 2" port with as few wasted photons as is possible, adding as much as 10mm more clear aperture over legacy adapters! And it costs no more than you would spend on a T-Ring and a good quality 2" T-adapter.

Only $79.00 Visa/MC/Discover/AmEx accepted.
