Thanks for the report Trevor! For benefit of those not familiar with Celeron's model numbers, Trevor's got an f/5 8" Newtonian.
How do you like the 14mm XW in that scope? I found the same thing Mike did at f/5 and f/4: too much field curvature, unsharp near edge of field. OTOH, the 10mm and under are perfect. Yours is the first report I've read about one of the 2" XWs. Sounds like a winner!
Be sure to bring the XW-30 to the Ballarat camp!
