What I think may be happening is that the driver is returning the RGB CCD Data as three separate planes, for R, G and B.

Not sure if the cast from Int32 to Uint32 will fail but from [,] to [,] definitely will.
Providing RGB data in this form is allowed in the ASCOM specification.
I guess that Raw will provide a single plane with the raw data, it will then need debayering as part of the processing.
