I also split Rukh (Delta Cygni) at 140X and 167X. I did notice that when Rukh is high up in the southwestern sky, the B component seem to have "moved" to the 6 o'clock position in my refractor with north roughly to the upper right (if you get what I mean).I have mirror diagonals in place. I do get the teardrop effect at midrange magnification.
I separated 15 Aquilae very easily at 11X and 23 Aquilae at 140X and 167X. Both are very nice through the eyepieces. My guidescope is sufficient for 15 Aquilae. The separation of 23 Aquilae is 3.2 arcseconds, and its magnitudes are 5.3 and 8.3. The PA is a mere 2.degrees. So it is "straight up" as I view it.
If it is clear tonight, I want to estimate the magnitudes of 2 variable stars: Carbon star V Aquilae and AG Pegasi. The latter has had quite an outburst of late.
Clear skies to all,
(Especially for Monday morning's Total Lunar Eclipse)
Aubrey.
