Adapter großes SC-Gewinde (3.3") auf standard SC-Gewinde (2")

This Ring was designed SPECIFICALLY for Celestron C11 and C14 telescopes in order to reduce vignetting.

It transforms the large 3,3" SC-thread to the standard 2" SC-thread in the same way as the ring already present in the C11 and C14. However, it provides an opening of 45,7mm while the original ring of the C11 and C14 only has a 38mm opening!

Thanks to this ring, you can enjoy a larger field of light to your 2" eyepiece your big sensors and prevent vignetting with focal reducers!

The ring is made of quality black anodized aluminium. It will also fit the large 3.3" SC-thead on Meade telescopes.
