TS Optics TSROTM68 360° Rotating Quick-Release Adapter M68x1
If you work with the professional M68x1 ZEISS-style thread system, you probably know the frustration of losing precious minutes when switching cameras or searching for a guide star. The TS Optics TSROTM68 adapter solves that problem directly and without compromise. It offers fast accessory swapping and smooth 360° rotation - all within just 10.5 mm of optical path. Knurled locking screws allow safe, confident handling even with gloves on during cold nights under an open sky.
Two-part design for precise, stable connection
The adapter consists of two separate parts. The inner part features a tapered cone that ensures a firm, secure connection to the telescope. As you tighten it, it self-centres automatically - so you always achieve an accurate and symmetrical fit. The outer part carries the camera connection and is secured with three screws. Thanks to generously thick walls and sufficiently long threads, the adapter handles heavier accessories with ease, without any unwanted flex or play in the joint.
Quick release - swap your camera in seconds
Anyone who has ever struggled with unwinding cables or carefully unscrewing a camera in the dark will immediately appreciate the quick-release function. Here, you simply detach the camera in a matter of seconds - for example, to clean dust from the sensor. The thread does not loosen on its own, and cables stay untangled. 360° rotation lets you position your imaging target precisely on the camera sensor without physically rearranging the entire setup. This is especially useful in combination with an off-axis guider: place the TSROTM68 adapter in front of the guider, rotate it freely, and significantly expand the field available for finding a bright guide star.
Open port protection - no improvised solutions needed
When you detach the camera - for example, because you are switching to a different device - one port remains open. Instead of reaching for improvised solutions, simply fit the counterpart from a second TSROTM68 adapter together with a suitable cap (available in the accessories section). The port is then reliably protected against dust and moisture. It is a small detail that makes a real difference at the end of a long night session.
