I use in my project astronomy cmos camera qhy5. But the built-in processing and Open cv video library does not see it. What can be done? What are the cameras running processing??? Thank you in advance. (built-in laptop camera works perfectly.) Here is the link to the camera: http://www.qhyccd.com/index.html#
