Third-generation filter wheel with QHY camera third-party software MaxIM DL.

 

Filter wheel 

control with ASCOM under MaxIm DL:

 

 

First, we also need to install the MaxIm DL, the filter wheel drive, the camera drive, the ASCOM 
driver for the filter wheel

ASCOM Driver

4PIN

 and the ASCOM driver for the camera. 

Then, connect the filter wheel and camera with 4pin wires in sequence (except for the special trigger 
cable except QHY9), connect the camera and computer with USB cable, and connect a 12V power 
supply to power the camera. After the correct connection, the third generation filter wheel will 
automatically rotate two turns and then rest. 
Open MaxIm DL, take QHY178 as an example, click on Camera Contorl (the icon with a box in the 
picture). 

 
 
First follow the steps to connect the camera (as shown) 

 

 
After connecting the camera, go back to the interface and select Setup Filter to select the filter 
wheel. Follow the steps (as shown).
