I really think CA is over-rated sometimes - I wouldn't worry a ZOT about any CA in those moon images. It's not an achromat, so it will control the CA well enough. I did image with a 150mm achro once, and the results were disgusting.
I still use a Vixen and Tak fluorite doublet for imaging alongside my quad FSQ85. I don't find it an issue at all.
