TS Optics 360° M117 Rotator
In astrophotography, the orientation of your camera relative to the target can make or break a shot. The TS Optics 360° M117 rotator solves this problem in a simple and reliable way - it lets you rotate your camera a full 360° without touching the rest of your optical train. The rotator holds its position securely during long exposures, where even the slightest movement can ruin an entire sequence.
Precise centring, no optical shift
The rotator for RC telescopes with M117x1 thread uses a system of three adjustable screws that press against a grooved ring gear. This keeps the rotating mechanism accurately centred and eliminates the risk of optical axis shift when repositioning the camera. The movement is firm yet smooth - ideal when you need to fine-tune your composition just before starting an imaging sequence. The build quality meets the demands of both field use and observatory work.
Compatibility and optical length
This rotator is designed primarily for larger RC telescopes from GSO and all TS telescopes with M117x1 thread. It connects to the telescope via an internal M117x1 thread and to the camera via an external M117x1 thread. The optical length of the rotator is 10 mm. You must account for this when calculating your total tube length and setting the correct back focus distance.
Who is this rotator for?
The TS Optics M117 rotator is a practical tool for any astrophotographer working with large reflector-camera systems. It removes the need to dismantle the entire imaging train every time you want to change the composition. Easy to use, solidly built, and with a standardised M117x1 thread, it is a reliable part of any astrophotography setup.
