Rowland/Alistair,
Whoooo
You've opened one hellava box with that AA filter comment!!!
I did the usual on-line search and I'm amazed that the issue of Moire fringes/ anti-aliasing hasn't come up before in the amateur astronomical community!
Sure, we all talk about the loss of resoution due to the Bayer matrix, but few (if any) take note that the inbuilt "AntiAlias" filter element actually blurs the image - on purpose, to prevent (or reduce) the Moire effects...
What does this mean to our "highly detailed DSLR images" or in my case the definition of fine absorption lines in DSLR spectral images.....
Hmmmmm
Need to spend a but more time and research on this one.
Thanks for raising it to the consciousness level.
