Hi

I use the V4L2 CCD driver to guide my scope. I often have the problem that I am totally lost
in misconfiguration in the V4L2 Control tab of ekos. After (mis)adjusting the image quality
for better guiding it feels quite annoying to find any default value a control. If it would be somehow possible
to query the v4l2 device for default control values and add a button to default all ctrl's that would be very nice.
Another thing would be to also add sliders for the "Exposure(Absolute)", "Gamma" and "Brightness" ctrl.

I took a look in the v4l2_base.h and v4l2driver.h/cpp files but that is far beyond my programming knowledge.
