Bought the Orion 0.8X refractor reducer for $145 today at Sirius Optics in Brisbane, so we shall see how that goes tonight on the ED100. Doesn't reduce it MUCH (from f/9 to f/7.2), but should be a big improvement. Be interesting to put it on the ED80... that would go from f/7.5 to f/6... not much in it
