The f/5 version of the scope will suffer from some chromatic
aberration for photography BUT, there have been some very nice B&W
pictures posted on alt.binaries.pictures.astro taken with an H-alpha
through this scope.  So if you don't mind doing tricolor imaging with
filters, this is much more economical than a APO.

The f/5 is on my wish list :-)
