SC Adapter for Skywatcher Maksutov Cassegrains with 66.5mm thread
Adapter for Skywatcher Maksutov telescopes to convert your Maksutov's visual back to a SC threaded back.
Please note, currently there are (at least) two different thread sizes on various Maksutov telescopes. This adapter fits only those Skywatcher and Orion Maksutov telescopes that came with a male 66.5mm thread.
With the help of this adapter you'll be able to use a wide range of SC accessories with your Skywatcher or Orion US Maksutov-Cassegrain telescope. These accessories include various SC threaded reducers (e.g. Celestrn f/6.3 reducer) and various SC-threaded 2" star diagonals
The adapter has a very short optical length and screws directly to the back end thread of your telescope.
This adapter will only fit on Skywatcher Maksutovs with the 66.5mm thread. These are the Maksutovs originally supplied with a 2" adaptation. Skywatcher Maksutovs that already come with a 1,25" adaptation from the factory unfortunately have a different thread. This adapter will not work on those Maksutovs, but please check out our alternative Maksutov SC Adapter here:
