Thanks Ivan - I think I was in the ball park then.. shooting at 15 fps the longest clip had about 2500 frames so under 3 minutes.

From the manufacturer's website: 'The StarShoot Solar System Color Imager IV features an integrated IR-cut filter to block both ultraviolet and infrared light' -

I was not using any filters with the CCD, this being my first outing I did not want to experiment too much..
I'm including an example of Registax processed image with the artefact present (I have magnified it in the second pic for clarity). This is after stack and wavelet processing. Can this be field rotation?
