Quite right - I did clean it just now. Clean as a whistle now.
I will build a flat library later today with the light box for each telescope. I intend running this camera at -35° constantly (which all accounts and users reports says it will all year round), so will build a -35° library for lights, darks and bias frames - thinking 100 frames per subframe type should tide me over.
Now to test if the shutter latency recording function works. Should help with time tagging the subs.
