Hi Rob,
thanks for your reply.
I will need to review software at some stage.

Beware of the high speed download on a QHY9-M.
See the picture which shows dark frames.
The high speed readout has a noise level 4 times higher than
the low speed download which is about equivalent to the sky noise
in Melbourne - an average of 4,225 bits out of 65K bits.
High speed is the default readout so it needs to be unticked.

cheers
Allan
