QHY 3rd Generation M Color Filter Wheel - Standard Thickness

Combining an ultra-thin stepper motor drive with the capacity for fully automatic filter switching, QHY's innovative new third generation QHY color filter wheels provide state-of-the-art performance. This specific version has a thickness of 20.5 mm and accepts up to either five 2" or 50 mm filters. As the standard medium filter wheel model, the filter thickness maximum for mounted filters is 10 mm, excluding filter thread height.

Ultra-Thin Hybrid Stepper Motor Drive

For their 3rd generation color filter wheel design, QHYCCD has selected a high quality ultra-thin hybrid stepper motor. Contrary to PM stepper motors employed by a lot of other filter wheels, this hybrid stepper motor offers better precision as well as a smaller step angle. The motor is enclosed to prevent dust from entering, thus improving reliability and prolonging motor life. Plus, the filter carousel can be rotated in both clockwise and counterclockwise directions for conveniently quick rotation completion.

Friction Drive with Zero Backlash

With this new 3rd generation color filter wheel model, QHYCCD is using a friction drive that results in zero operational backlash, a step up from their previous 2nd generation filter wheels which used a gear drive.

USB Serial Port Switch

Serial port switch supports fast serial communication mode to USB communication mode switching.

USB Powered

This filter wheel's firmware is open source and compatible with Arduino. It supports QHY 4-pin connection control mode and is designed to be compatible with QHY's Off-Axis Guider (OAG) for the corresponding size.

Beautiful Appearance

The main body of QHYCFW3 filter wheels is cut from a single piece of aluminum using a precision CNC machine. Expertly crafted with a beautiful finish, the small design of this filter wheel will make you never want to put it down!

Expressly designed to enable the installation of unmounted filters with a variety of thicknesses, this standard Medium filter wheel model accepts the installation of mounted filters under 10 mm thick, as well as unmounted filters of differing thicknesses, to the same filter disc. This provides faster and more precise filter positioning.

Please Note : Image shows two separate versions of the QHYCFW3 filter wheel. If you purchase this item, you will receive only the 5 position filter wheel.
