The Baader ETX / NX4 Universal Photo-T Adapter is a multi-functional adapter for Meade ETX, Celestron NexStar 4 and C90 telescopes with a male 1.375″ thread and allows you to connect photographic accessories that use either standard T2 (M42) threads or 2″ SC threads.

The adapter consists of two parts:

• 1.375″ female to 2″ SC male adapter for connecting accessories with 2″ SC threads to the telescopes mentioned above. This also includes an internal thread for mounting a 1.25″ filter.
• 2″ SC female to T2 male adapter for connecting T2 (M42) accessories such as cameras and T-rings.

Both adapters feature a knurled ring for easy gripping.

Note: only certain C90 spotting scopes have 1.375″-24 threads. Make sure you double check before ordering.
