Oops, I should have added that this isn't the first time I've tried for Rup 106 in the 4.5". First time there was nothing there, but in 2008 in pretty good conditions (but not as good as last night) I had tantalising glimpses of "something" but nowhere near enough to convince me that I had seen it. Strange how time gets away and it's three years later before I try again!
Cheers -
