I’ve had this filter wheel for a few years and it works perfectly. TheZWO LRGB set are in the wheel which is why their case is empty and leave room for a methane filter, U Venus, and room to spare. It is ASCOM compliant and can be driven Firecapture and no doubt many more. Asking $230 for the wheel and the filters, contact Jim at JamesDixonLR@gmail.com.
