QHY 3rd Generation S Color Filter Wheel - Standard Thickness
with 7 Position CFW3S for 31 mm or 1.25" Filters
QHY is introducing a revolutionary new 3rd generation filter wheel featuring an ultra-thin stepper motor drive and fully automatic filter switching capability. This particular model measures 20 mm in thickness and accepts up to seven 31 mm or 1.25" filters. Since this is the standard version of the small QHYCFW3, maximum thickness for mounted filters, excluding filter thread height, is 10 mm.

Ultra-Thin Hybrid Stepper Motor Drive
QHYCCD has chosen to use an ultra-thin, high-quality hybrid stepper motor for the design of their third generation filter wheels. When compared to PM stepper motors used in many filter wheels, this hybrid stepper motor offers improved precision and a smaller step angle. An enclosed motor prevents the accumulation of dust for enhanced reliability and longer life. In addition, as filter rotation is reversible, the carousel can be rotated clockwise as well as counterclockwise for convenient filter access.
Friction Drive with Zero Backlash
The most innovative difference between the motor drive used in QHYCCD's 2nd generation filter wheels and these 3rd generation filter wheels is that this new filter wheel uses a friction drive for zero backlash during operation, while the previous model used a gear drive.
USB Serial Port Switch
Incorporates a serial port switch to enable fast shifting between serial and USB communication modes.
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 this QHYCCD 3rd generation color filter wheel is cut from a single precision CNC machined piece of aluminum. It boasts a skillfully crafted and elegant finish. As soon as you hold this filter wheel in your hands, its small design will prevent you from ever wanting to put it down!
Specifically designed to allow unmounted filters of varying thicknesses to be installed, the filter carousel in this small model QHY color filter wheel standard version also permits the installation of mounted filters under 10 mm in thickness to the same filter disc. Filter positioning is made quicker and more accurate.
Please Note : Image shows two separate versions of the QHYCFW3 filter wheel. If you purchase this item, you will receive only the 7 position wheel.
