Grab yourself some TV Ploosls, or if you like the Meade 4000 (I have a set of Meades myself....can't complain about them). Try
Bintel. Max useful mag for your scope is around x240, so with the 8mm EP at x183 you're getting near that. Haven't tried the shorty barlow myself, but so long as it didn't introduce any astigmatism or such using it with a long FL scope, you'll be OK with it. Seems Bintel thinks they're good with ETX's. With wide angle or UWA's, don't skimp on the EP....cheap of anything will perform badly, and with optics designed for extra wide FoV's you'll notice it more than with ordinary EP's. If you're going to get them, save up and get some better quality gear like Naglers or Ethos EP's. Not cheap, but they're a class or two above your average WA or UWA EP. Even the Meade 5000's look alright and I've heard good reviews on them.
