TS-Optics short T2 Adapter for 2" Eyepieces & 2" Receptacles D=50.8 mm

TS Fotoring50 - T2 connection for 2" eyepieces

Connect your SLR camera or system camera directly to your 2" eyepiece. All you need is this ring and the matching transition to T2, such as a T2 adapter or the matching transition ring to the lens filter thread, for system cameras without interchangeable lenses. You gain a lot of field of view and can take advantage of the strong optical performance of your 2" eyepiece.

The Fotoring50 fits all 2" eyepieces with a straight sleeve from 48 mm to 50.6 mm. You can find out the diameter of your eyepiece by pulling off the rubber eyecup and measuring it. Then simply fix the photo ring with the 3 M4 knurled screws and you´re ready to go.

The Fotoring50 also fits over 2" receptacles. The outer diameter of the receptacles is between 50.2 mm and 50.6 mm (depending on the manufacturer). The photo ring is simply put over the 2" sleeve and fixed with the three knurled screws.

The advantage - there is no shorter T2 connection

The Fotoring turns your eyepiece into a projection lens with a direct T2 connection. The short design has two advantages over a conventional projection adapter:

Telescopes with very narrow focal positions (like Newtonian mirror telescopes) are usually not designed for photography. You can attach your camera mechanically, but you wouldn´t get any sharpness, because the focuser will bump inwards beforehand. You can easily focus with the photo ring.

If you want to photograph with your digital camera without interchangeable lenses, you have to get as close as possible to the eyepiece with the lens. The view from the side shows that the photo ring offers the shortest possible construction, you can get close to the eyepiece with the lens and thus gain much more field of view.
