Starlight Instruments Eyepiece Adapter for Celestron/Meade 6.3 Focal Reducer

Its primary purpose is to attach a Celestron or Meade f/6.3 focal reducer to any 2.0" opening. These reducers typically have threads designed for cameras, so this adapter gives that threaded connection a 2.0" barrel that fits any 2.0" opening, enabling wide-field visual observation through your SCT.

By letting you mount your f/6.3 reducer in a 2.0" focuser, this Starlight Instruments adapter lets you take visual advantage of the reducer's wider, faster field. In an 8" SCT, you'll be able to frame large star clusters and nebulae that would otherwise be too large for the telescope's native f/10 field of view. The adapter ensures a rigid connection, preserving the sharpness provided by the reducer.

This adapter is specifically designed to thread onto the Celestron and Meade f/6.3 focal reducer/correctors. It is not intended for use with other models, such as f/3.3 reducers or those from other manufacturers, which may have different thread specifications or back-focus requirements.

The key advantage is the manufacturing precision. Starlight Instruments machines their components to extremely tight tolerances, which guarantees a solid, flex-free fit. This eliminates potential image shift or optical misalignment that can occur with lower-quality adapters, ensuring your optical train remains perfectly collimated from the telescope to the eyepiece.

It does not hold a camera itself. It attaches the reducer to a 2.0" opening, and the camera connects to the reducer's rear thread. For imaging, you would typically connect your camera directly to the reducer's threads using appropriate T-rings and spacers.

No. This adapter does not hold eyepieces. It is a 2.0" barrel with an SCT 2"-24 thread that the f/6.3 reducer screws onto, and the barrel is held by your focuser's clamp.
