Thanks for the comments all.
Greg;
The tracking is compensated by the adaptive optics. I did not see what ccd autopilot chose for guide correction exposures, it is usually less than half a second, although I cannot say for sure, was asleep when all this data was captured. This is the first data set that I have successfully got with setting a target and walking away. All functions are automated, adaptive optics, focusing, guide star selection, plate solving, rotator, pointing, darks, flats etc.
Even without adaptive optics the ccdap guiding algorithm works better than any other guiding program I have used. You must be sick of hearing me bang on about adaptive optics.
With my last refractor I did not have too much trouble getting round stars at 795mm, maybe losing 1 in 10 subs, without adaptive optics with the eq6.
I did a DIY hypertune on the mount and it does track well. I personally think they are the best value mounts around.
The green tinge... I really hacked hard on the green and has been mentioned by others as well, I obviously did not hit it hard enough. I think it maybe some part moon and light pollution, I do live a block from the cbd in bathurst. Time for a play in ps....
