Hi Lee. Sorry to be a wet blanket, but suggest that you get the opinions of Peter (PRejto) and Greg Bradley before you buy. Peter had problems with halos around stars that could have been due to chromatic aberration in his good quality refactor. It seems that refractors generally have deep blue/UV point spread that is not visible by eye (the eye just does not see it very well), but that stands out in an image from a Sony camera because of the very high blue/UV response of those chips.
I don't know about the WO, but it seems that an AP or TOA may be the best refractors for minimising this problem - many other high end designs are great for visual use, but may have problems when used for broadband imaging.
If you have that sort of money, maybe you could give the SW Mak Newt a look - it isn't a refractor, but should (just) work OK on your EQ6, be pretty much plug and play (fully corrected out of the box) and with no CA issues on your chip.
regards Ray
