I need to find some astronomical/ spectroscopic examples of Moire fringing/ antAlias effects before I start to panic.

Yes, it is one of the reasons I've been using fuji cameras, the later ones have no AA filter and the difference is noticeably sharper images than my Nikon which has the same size sensor, same MP and same lens. It is one of the reasons I have not been a fan of DSLRs for astronomical use, the AA filter is great for stopping moire on patterned shirts in portraits, but not what you want for a 'scientific' instrument.
