I just purchased the Pro version of this camera after owning the Version 3 because I couldn't get good flats with the version 3. The flats on the Pro model are fine but the dark noise is terrible. It is nothing like the dark frame available for download on the sales page. Attached is a screenshot and here is a link to a fit file:

If this is the new camera's dark noise then I don't think I can keep it. Let me know if there is something to be done about it.
Thanks,
