I'm using kstars/EKOS 2.9.7 on my laptop (openSUSE Tumbleweed x86_64) to control an ASI1600MM Pro camera. In 16bit mode the live stream view does not work. I just get a completely white image. changing exposure in the viewer tab does nothing. (I wonder if it's a driver thing - oacapture also has issues recording 16bit streams)
This should be fixed with upcoming 3.5.0 release.
Confirmed. Tried both a mono ASI1600 and a color ASI183. Both properly record 16bit subframe movies in SER format.
