QHYCFW2-S

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.
