The Mini filter wheel with off-axis guide prism, is a compact solution for mobile setups, or where the lightest possible wheel and guider are required. The wheel is USB controlled and powered, with 5 filter positions, and the OAG is pre-set to be close to par-focal with most SX cameras. The SX Lodestar PRO & Ultrastar PRO guide cameras are an ideal match to the OAG pick-off tube.
The Mini filter wheel uses the same control protocol as the smaller SX wheel and has both USB and serial inputs. The entire electronic assembly is USB powered and does not need an external power supply.
