I have the Hyperion in 13 and 17mm sizes (and the near identical Orion Stratus in 8mm) and I have to say I really enjoy using them and love the views I get - and although I have looked through a few Naglers I haven't had the chance to compare with a Pentax XW, or even XF series for that matter, so I can't comment on the differences.
Perhaps ignorance is bliss in this occasion.
Rob maybe I can steal a bit of a view through one of your XW's at Astrofest this year ... or maybe I shouldn't, so that I won't have to start saving money again.
