Re: Your Report
Hi Doug,
Great report as usual mate.

I assume you mean Nu Scorpii (14 Scorpii) near Beta. Nu is actually a really lovely "double-double" but a somewhat more difficut split than Epsilon Lyrae. I can't recall the splits at the moment but I use the tighter pair in winter as as a seeing test. From memory it is at about 1.1". The wider pair is much easier and the pair-to-pair split is quite do-able in binoculars. Really nice.

Indeed! The north-south spine of stars starts to become noticable from about 4" in aperture (the point where it begins to show _signifiicant_ resolution) and reaches its "distinctiveness peak" at about the 12-14" mark and from that point upward in aperture, it starts to get lost in more and more resolved stars. It is fading well and truly at 24" and by the time you get to 40", it is well and truly swamped by the other resolved stars. It is a lovely object.
The Herald-Bobroff serving you well?
Best,
