I'm still having some troubles with my back, so it was another night with the 63mm Zeiss, as I couldn't move the big 6" ED. The seeing was very good, up high in the sky, so I concentrated on tight-ish doubles in Cygnus.
First was STF 2666, which I have already seen before, but tonight I noticed that it not only has three companions, but that there's also a faint, fairly wide double star just 103" or so to its NE, magnitudes around 10, with one about half a magnitude fainter than the other. I have been unable to identify this pair, if it is a true, known pair, that is (I suspect it isn't). Using an image from Digitized Sky Survey, I made a crude measurement on my screen with a caliper and came out with a separation of 15" and a PA of ~40°. All six stars were seen at 179x (4.7mm ES82). The B companion to STF 2666 is a bit faint, but not super hard. A very nice field.
Tonight I managed to find ORL 6 AC, which has eluded me earlier, but I'm not sure I could split it. I sometimes thought I saw it slightly elongated at 179x, but it was faint enough, that it was too fuzzy to see with certainty. This is one for the 152mm.
STF 2609 is quite close by. The companion is faint and it's tight, but a very nice sight at 179x.
STF 2668 has a faint, rather close companion. Visible at 125x (6.7mm ES82), but better at 179x.
49 Cygni is SUPERB in the 63mm! A faint companion, sitting right on top of the very dim first diffraction ring of the bright, yellowish primary at 179x. Stunning!
V389/STF 2762 has very similar stats to 49 Cygni, except it's a bit wider, yet manages to look completely different! It looks fainter, yet shouldn't.
Mu Cygni was steadily seen tonight at 179x as a bright, round star with a fainter bump on it. A very nice challenge for the 63mm in good seeing. It reminds me of Zeta Herculis in a 4".
STF 2741 was just separated at 179x. Semi-faint, but not hard.
STF 2732 was much harder, despite being a little wider, its companion being much dimmer. Not too easy at 179x.
Psi Cygni wasn't hard. A brighter version of 49 Cygni.
