Both the 500d and 6D images were taken in a pitch black observatory. No chance what soever of light coming in from viewfinder, otherwise it would be on both images.
2. Rotation experiement.
Last month captured ngc253, Moonlite focuser was rotated to a different angle. There was still a flair but in a different location.
A mate has suggested that because the 6D is full frame i could be getting reflection of the scope or focuser barrel. My moonlite focuser is 2" and he suggested i may need 3"
Anyone care to comment and is anyone else out there shooting using a full frame DSLR on a 120ed refractor.

1. Are you using liveview? Try it without. What about your nightscape shots that you mentioned ?
2. Try the rotation on the same subject .. that will confirm if the light source is a star outside of view.
I thought your obsy was pitch black why would full frame vs crop make a difference, and if its in your nightscape shots? The suggestions/ tests listed by people will help us help you identify the problem.
