For low power the Andrews UWA (=1rpd) is too expensive for an EP you will probably want to upgrade eventually anyway IMO. Better off with a 30mm GSO Superview for that purpose. if you want the uwa wait/ask for discount to $99.

The comment in bold about the 2" barlow above really caught my eye.
I was disapointed to miss out on the UO 2x barlow before it went out of production, is this orion really the same Barlow ?
If so, where can you get them in Aust ?
