Hey Doug, that shot is corker!
Well done. The MPCC is the culprit. True you'll get the reflection like halo if you keep the glass nosepiece but with the MPCC on regardless you'll get the donut reflections offsets on bright stars. I'm now convinced it's an internal reflection within the MPCC. I have had no reflection with the Hyperstar. Not the same shapes anyway. So I reckon it's not a problem with the camera as far as I can tell.
Hope everything is falling into place for you, have a good Xmas, stay safe and healthy and all the best for 2010.
