Description/Uses:
- Adapter with Celestron's large 3.28" female SCT threads on one side and an M54x0.75 male thread on the other side
- For use with Celestron's 9.25" EdgeHD and all 11" and 14" SCT/EdgeHD telescopes. Allows you to use M54 threaded cameras and accessories directly on the telescope without stepping through SCT adapters, which you have to do if you use the included small 2" SCT adapter that these telescopes come with. For EdgeHD scopes, you will need to add additional spacers (not included) to adhere to the correct back focus requirements of those scopes.
- Also features a short M48 female thread inside the M54 male thread. This can be used to attach 2" filters inside the adapter on the telescope side.
- Not for use with Sky-Watcher's M54x1 threaded accessories
Features:
- Precision machined, black anodized aluminum
- Large knurled grip pattern on the outside
