Thanks Tim, sbrooks, Ron and Mark.
Tim, the Sky 90 is considered to be a semi-APO due to the fact that it's only an air-spaced doublet. The triplette APOs add the extra objective to get the color correction job done better and the quads are even better. I find the small amount of chromatic aberration in the Sky 90 to be minimal and really doesn't bother me. It surprises me that I don't see more people with good things to say about it for imaging, I enjoy mine a lot and can't imagine parting with it.

Greg Parker uses a Sky 90 (when not using a Hyperstar setup) and he has produced some stunning work.
