Step 4 Install the telescope
The other side of the filter wheel can be connected to the telescope by screwing on a standard M42
(M) to 2 inch ring.
Step 5 Power connection
Connect the camera with the special crystal head external trigger control line connected to QHY9.
Insert the filter wheel interface into the crystal head. The golden interface is connected to the body.
Because the control line is connected to the QHY9 camera to control the filter wheel, it needs
external connection. The 12V power supply provides the working power of the filter wheel, so the
other connector is connected to the power supply.
Finally, use software for verification. During the normal rotation of the filter wheel, the multi-color
lamp will continue to be bright. When the filter wheel turntable stops, the multi-color lamp will be
extinguished; the color of each of the three color lights in each filter hole position will be different
(each filter) The hole position corresponds to one color). The specific control method is shown in the
third part.
Note 1: Another connection method for the new version of QHY9
The new version of the QHY9 has six threaded holes in the top cover, so you can also choose to
connect directly to the holes in the filter theory (you can of course continue to use the old method).
If you want to connect with the new method, step one will not need to install the filter wheel special
ring, but use four screws to fix the filter theory on the QHY9 from the inside of the filter wheel. A
black sponge gasket is required between the QHY9 and the filter theory to ensure no light leakage.
