QHY Filter Wheel with QHY LRGB mounted 2" filter set.
This wheel has M54 female in and out so the hole is big enough for most large format cameras and the carousel takes 5 mounted or unmounted filters from 2" mounted to 50.8mm unmounted.
It has M54 to T-Thread adapters to give you T-Thread male out and T-Thread female in plus a 2" nose to T-Thread male which screws into the front adapter.
Comes with the serial control cable and a Keyspan usb to serial adapter.
I've also attached an image taken with these filters and a large format camera.
