Hi John B & All,
Bad luck in not being able to head up to Coona.
Those are quite impressive SQM figures for Canyonleigh.
As a matter of interest, here is a copy of what I posted on AMASTRO about this challenge PNe:
"I recorded it in my 46cm f/4.9 at 12.30am local time (13.30hrs UTC) on Sun night/Mon morning 25/26012009 at my Southern Highlands site about 130km SW of Sydney. I'd rate the seeing at about 7/10 and the SQM/L gave a reading of 21.53 equating to a ZLM of 6.40 about 1/2 hr before the observation.
The field is pretty easy to acquire about 28 arc-min NE of 3rd magnitude SAO 250905. It was very tough to see at x185 without filtration but a fairly simple object with filtration (UHC and OIII tried -- UHC seemed to give best results) as a small, perhaps 25" x 15" oval or oblong in about PA 90 of quite LSB mist with a weak central brightening and very diffuse edges, nearby and almost running parallel to closely spaced mag 11 and 13 stars. The best view was at x247 with a 9mm T1 Nagler and UHC. The observation was confirmed by a very experienced observer Gary Mitchell of the Sutherland Astronomical Society and by three other relatively inexperienced observers."

Love to tell you more -- sworn to secrecy!! It is pretty surprising it has never been noted before and I was even more surprised to *detect* (and I mean "detect") it visually. I think I saw it twice over about 5-6 mins. Another very experienced observer (Gary Mitchell SASI) did the same
So, there you go, and it was a good night indeed!
Best,
Les D
