Hi All,
I have been considering purchasing a cooled astro camera for a while.
As part of researching various makes & models, I have been wondering why related mono and colour astro cameras typically list the same number of pixels. eg:

I have read that colour cameras typically incorporate a "bayer matrix" over the sensor filtering each 4 physical sensor pixels into primary colours (1 x red, 2 x green, 1 blue), combining into 1 colour pixel in the final image.
If that is the case, then shouldn't a mono camera image have 4 times as many pixels as a related colour camera (eg. Orion Parsec 8300M, versus Orion Parsec 8300C)? Or are the actual camera sensors completely different?
Can anyone advise?
