QHYCFW3 details :

QHYCCD selected a high quality ultra-thin hybrid stepper motor for the 3rd generation filter wheel design. 
Compared to the PM stepper motor used in many filter wheels, the hybrid stepper motor has higher
precision, smaller step angle, and is more expensive.  The motor is enclosed to prevent dust from entering
the motor, thus improving reliability and motor life.  The direction of filter rotation can be reversed:
The filter carousel can be rotated clockwise or counterclockwise to complete the rotation quickly which is
very convenient.

Regarding the evolution of the motor drive, our 2nd generation filter wheels used a gear drive while
this 3rd generation filter wheel uses a friction drive that with zero backlash. It also positions and stops
with high precision.

The QHYCFW3 main body is cut from a single piece of aluminum by a precision CNC machine. 
The craftsmanship and finish are exquisite.  When you hold the small design, you do not want to put it down!

There is a switch button on the QHYCFW3.  The serial port switch can accommodate fast switching
between serial communication mode and USB communication mode.
There are four versions of the 3rd generation QHYCFW3 filter wheel: QHYCFW3XL (extra-large size),
QHYCFW3L (large size), QHYCFW3M (medium size), and QHYCFW3S (small size). Both the QHYCFW3M
and QHYCFW3S are also available in a standard version (-SR) and thin version (-US). For details, please
see the specifications page. 

QHYCFW3 support two socket mode. One is the 4PIN QHYCFW socket. If your QHYCCD camera has
the 4PIN socket you can connect it directly with QHYCFW3. There is the 12V power in the 4PIN socket .
So it does not need any extra power supply.  If you have no QHYCCD camera or the camera has no 4PIN
QHYCFW socket. You can use the USB socket to connect with the computer.  Anda  the QHYCFW3 can
be powered and controlled with USB port.  Please note the current requirement when using the USB cable
is higher (780mA) than the USB2.0 port can supply and some computer will limit the current to 500mA.
In this condition, QHYCFW3 can draw the power from the QHYCFW socket port (the 6PIN RJ11 port in the QHYCFW3)
and you need a 12V to RJ11 cable to power the QHYCFW2. When using this method.
The current drawing from USB cable will reduce to less than 100mA when motor rotating. 
(* The 12V to RJ11 cable is in the standard item list after 2019.4).

OAG are available for Small
Mediuim, and Large Filter wheels
QHY OAG -  Thin and Flexible Setup
QHYOAG is has the thin and solid design.
The OAG main body is just 10mm thickness.
But you may need a M42 thread or M54 connector board with 3mm thickness, in this condition it is 13mm totally
There is six 3mm through hole in the OAG.
It can connect with the QHYCFW2, QHY "A" series camera directly.
If you have no QHYCFW2 and QHY "A" series camera, you can also use this OAG directly with some adapters.
QHYOAG has three models. QHYOAG-S,QHYOAG-M,QHYOAG-L, in order to match the different CCD sensor size.
QHYOAG comes with a multi-thread 1.25inch focuser.
The focuser has a screw locker to get the guide camera solid fixed after focusing.
The prism position can be adjusted and it has a locker to fix the position.
The prism is 8mm*8mm size and the optic hole from prism to mirror is 8mm diameter.
