Looking good Roger.

Not sure about that Roger, it's a bit of a kaleidoscope of coloured stars.  I think it may need a bit of colour calibration.

You have some good data there.

I agree with Robert, a bit of a kaleidoscope of coloured stars.  It's probably a question of incorrect black level i.e. you've been too aggressive .
