Perhaps.
I installed a aperture mask over the CCD chamber that Apogee provided. If you look into the CCD chamber you can see most likely lots of shiny aluminium parts and soldered connectors that could easily cause reflections.
These then bounce off the flattener that you must use for large chipped cameras and you get your reflections perhaps.
Your AP scope undoubtedly has excellent baffling and coatings so perhaps making a mask out of black thin cardboard that is about the same size as the chip and putting it over it may help.
There was a long thread about this on the Apogee group that culminated in Apogee issuing a free mask to U16M camera owners. The guy there who pioneered it showed images with and without his black cardboard mask and it definitely made a difference.
Another thing that may help is to blacken the edges of your filters.
Time will tell Mike but I haven't seen significant reflection problems with the U16M yet on any scope. It is one main reason I chose the Baader filters as they had the best results on reflections on big chip cameras.
