The acquisition board is a National Instruments LabView ADC. So, It's
more of a general purpose low noise ADC. It's a proprietary CMOS
sensor, so legally, I can't speak freely about the readout method. I'm
sorry.
It is not an astro camera, but I do come from the astro community so
I'm familiar with some of the specifics of astronomical
instrumentation.
Best regards,
Patrick
