TS Optics projection adapter with 2"/SC thread for 1.25" eyepieces Extends the focal length of your telescope. Suitable for 1.25" eyepieces up to 38 mm outer diameter To capture lunar craters and planets, the aperture ratio of the telescope has to be raised to approx. f/20 - f/30. A probate means to achieve this is eyepiece (afocal) projection. This adapter turns your 1.25" eyepiece into a powerful projection eyepiece.

Equipping the adapter The OPAD´s heart is a base adapter with T-thread on both ends. The eyepiece is installed here and is locked by two thumbscrews for perfect centering on the optical axis. Then, screw the T2 spacers above the eyepiece and you're ready to start!
Camera adaptation - DSLR cameras with suitable T-ring
- Compact digital cameras with fixed lens use an adapter to M54 filter thread. From this filter thread, adapters to other filter threads are available.
Recommended eyepieces for projection - DSLR camera bodies use eyepieces from approx. 6 through 15 mm. A good Ortho, Plössl or moderate wide angle is best. Ultra wide angle eyepieces are not recommended because of their distortions.
- For compact cameras with fixed lens, we recommend eyepieces with large eye lens and a focal length of approx. 20-25 mm. It should be brought as close as possible to the camera's lens.
