The M54 adapter for ZWO OAG-L allows you to connect ZWO's large free aperture off-axis guider to ZWO's cooled cameras without the need for a filter switch. The adapter ring can be screwed to either side of the off-axis guide and camera, making it a very robust, non-displacement unit.
The adapter ring has a width of 15 mm and an internal thread M54. Inside the device, it is also possible to use 2" filters with the standard adapter ring.
