QHY 7-Position Medium Standard Color Filter Wheel for 36mm Filters
The QHY “medium” motorized CFW2 comes standard with a gear-driven 7-position wheel that accepts 36mm unmounted filters (sold separately). There is also a medium CFW2 filter wheel available that comes with a 5-position carousel that accepts 50mm filters at the same price. You can find that CFW2 here.
The QHY CFW2 Medium Color Filter Wheel is only 21.5mm, or 0.85 inches thick, and weighs 1.55 pounds or 705 grams. The 7 position carousel is designed to hold seven unmounted 36mm filter with glass up to 8mm thick.
This is the second generation of the QHY CFW. Improvements to this solid electronic color filter wheel include moving the motor to a corner of the unit to increase the work area, and increased filter location precision.
The telescope side of the CFW2 sports a 3.5” deep M54x0.75 female connector as well as six M3 screw holes which allow you to connect the QHY-OAG. The camera side has a slightly shallower (2.5”) M42x0.75 female thread connector and six 3mm through holes. The camera connection has a 2mm deep stage designed to stop light leaks.
QHY CFW2 sockets include an RJ11 to connect your QHY camera, and a USB 2.0 to connect your computer. This color filter wheel can be used with other brand cameras with some slight modifications. A step-by-step set of instructions is in the manual.
