Thanks for the idea Ed, potentially shutter bump but have the camera on 2 sec delay timer when not using the cable release, I think this was just a timer shot.

It was near a road and there were cars going past not sure if one went past while the shutter was open.

And if the tripod wasn't secure and the camera dropped, I would also expect it to affect more stars.
Its a pretty solid tripod, manfrotto 055 with a stable head. I think if it was a bump it should have blurred the rest of the image. at 100% I cant see any blur in the smaller stars (taken M8 (I think) as an example) or milky way dust clouds however at full zoom there are more effected than can be seen in the IIS version
