- Direct from Camera body to 2″ Eyepiece Port.
- Bypasses T-Rings for 10mm Larger Clear Aperture!
- Reduced Vignetting, Lower Profile & Weight.
- Threaded for Standard 2″ Eyepiece Filters (48mm).
- Fully Baffled to reduce internal reflections.
Just say NO to T-Rings!
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 high end scopes wisely put 2″ eyepiece ports on them. Why then do we insist on putting a 1.5″ bottleneck between your camera and telescope?
Answer:
T-Rings have been around for decades, a legacy standard as outdated as 300 baud modems.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.
True-2TM is a true 2″ prime focus adapter that takes you directly from the cameras bayonet mount to a 2″ Barrel with as few wasted photons as is possible, adding as much as 10mm more clear aperture over legacy adapters! The largest clear ape
