I have the Orion Premium Zoom, and think it's quite good. [I think I've
seen that it's really a re-branded Vixen, but I'm not going to swear to
it...] It is pretty much parfocal throughout the range, and you don't get
too much darkening down at the 8mm level. I've used it for both planetary
as well as DSO viewing.
