Tonight's effort,
the 55mm spacer now in use. Coma is minimal but I still have
the elongated stars I've had all along radiating in a position angle
sort of 10 o'clock. This is NOT a tracking issue. It's on a live 1 sec shot
or a 10sec shot. Maybe the CCD is slanted slightly? A tip from Theo on it
here:

That and a weird sideways blooming effect on Eta
and a few brighter stars. Debayer artifact?
Seeing was not brilliant either tonight but I think I nailed the colour
albeit a bit unsaturated and lacking blue.
The debayer was done as per Doug and Marc's suggestion 7.8u sq
pixels with a 1x1 ratio.
Edit: 2nd result: 2 iterations of the same curve applied.
