- Third-generation QHYCCD ultra-slim filter wheel holds up to seven 1.25” mounted or six 36mm unmounted filters
- Ultra-thin hybrid stepper motor for higher precision and smaller step angles with zero backlash
- Easily switches from USB to QHYCFW serial port mode
- Attractive low-profile design in a CNC-machined aluminum body
1. Third-Generation QHYCCD Filter Wheels for Astrophotography
The QHYCFW3S-US is based on QHYCCD’s third-generation filter wheel design and technology.
This ultra-slim filter wheel incorporates a carousel holding six 36mm unmounted filters up to 5.5mm thick (not including the thread height of the filters).
The design of the carousel makes filter positioning quick and precise. Mounted filters less than 5.5mm in thickness can be installed, while unmounted filters of different thicknesses can also be mounted to the same filter disc.
2. Super-Thin Enclosed Stepper Motor
QHYCCD selected a high quality ultra-thin hybrid stepper motor for their third-generation filter wheel design. With this stepper motor, the filter wheel supports precise and fully automatic digital control when switching filters, yet it has a total thickness of just 15.5mm.
Compared to permanent magnet (PM) stepper motors used in many filter wheels, the hybrid stepper motor has higher precision and smaller step angle, ideal for demanding astrophotography applications. The motor is enclosed to prevent dust from entering, thus improving reliability and motor life. The filter carousel can also be rotated clockwise or counterclockwise for convenient filter access.
3. Precision Positioning and No Backlash
In this third generation QHYCCD filters wheel, designers incorporated a friction drive with zero backlash that also positions and stops each filter with high precision.
4. Two Control Modes
The QHYCFW3-series filter wheels include a switch to enable a fast change between serial communication mode and USB communication mode through a 4-pin QHYCFW port or a standard USB port.
The filter wheel is USB powered and uses open source Arduino-compatible firmware. It is designed to work with a similar sized QHY Off-Axis Guider (OAG).
5. Modern and Attractive Design
The third-generation QHYCCD filter wheels have exquisite design and appearance. The main body of the QHYCFW3-series is cut from a single piece of aluminum by a precision CNC machine and black anodized, making this a beautiful as well as a highly practical and functional device. Without filters, the QHYCFW3S-SR weighs 419g.
6. Available in 2 Versions
In addition to this 6 position, 36mm unmounted filter version, this item is also available separately in the following version:
- 7 position, 1.25" mounted or 31mm unmounted filters
