The QHYCFW2-S (small) holds five 36mm umounted filters or six 1.25-inch mounted filters in threaded cells. The filter wheel is only 15.5mm thick and weighs only 365g.
The QHYCFW2-S is the second generation color filter wheel. We improved both the mechanical and electrical design over the previous version. The new QHYCFW2-S has the following advantages:
Gear driven disk. Stable and solid.
Specially designed filter disk to allow different glass thickness for unmounted filters. From 0.7mm to 7mm.
Motor moved to a corner to increase the work area.
Increased the precision of filter positioning.
Supports USB port and powered by USB when connected with computer.
Supports the 4-pin QHY CFW socket on QHY11,QHY21/22/23 and InterCam series camera.
Supports the 2-pin socket with QHY9 (requires external power supply).
Open Source Firmware, Arduino compatible.
