bootes doubles

Last night started out with average seeing but it steadily improved during the session.  With not much happening on Jupiter, and the moon behind the median tree, I aimed the 12.5-inch to Arcturus and started in on some doubles.  Starting at 277x and going to 553x for the tighter ones; but with mixed results.

STF 1888: Pretty. Yellow and orange pair, ~6", 3 delta mag.  This is actually a sextuple system
14H 51M 23.38S +19° 06' 01.7" P.A. 301.7 SEP 5.56 MAG 4.76,6.95 SP G8V+K5V DIST. 6.71 PC (21.89 L.Y.)

Anonymous to north of STF 1888: very faint, very wide blue B to orange A star, 3-4 delta mag.

STT 288: 553x: Seen as a messy elongation to the A star at 277x; needed 553x to separate, resolved with the seeing.  Near equal yellow-white, ~1" or less.
14H 53M 23.35S +15° 42' 18.3" P.A. 158.1 SEP 1" MAG 6.89,7.55 SP F9V DIST. 47.64 PC (155.4 L.Y.)

STF 1865: very bright A with two very faint blue stars, very wide, as possible pairs. [This is a miss; separation is 0.4", so not seen]
14H 41M 08.92S +13° 43' 42.0" P.A. 289.3 SEP 0.4 MAG 4.46,4.55 SP A0V+A0V DIST. 53.88 PC (175.76 L.Y.)

CHR 41 & ENG 51: Viewed with the SA100 grating, but did not see double rainbow lines, which I had hoped would be possible for close "spectroscopic" pairs.  I read one has to see the spectral lines change as the B star revolves around the A in order to "see" a spectroscopic pair; for that I'd need to do imaging.

STT 279: Very close faint orange-red near equal pair, kissing in unsettled seeing but a definite split when it stills.  [Not seen -- I wonder what I saw?  This is a not too close unequal pair, should have seen it.]
14H 13M 49.46S +11° 59' 51.9" P.A. 257 SEP 2.2 MAG 6.84,9.13 SP K2III DIST. 170.94 PC (557.61 L.Y.)

Kui 66: Unresolved faint haze at 553x, but adding the apodizing mask and turning off my fan I had a glimpse of the B star 15% of the time, very small and faint, ~3" and 4-5 delta mag.  Both orange.  Definitely there.  [On a defocussed star image I noticed the fan causing turbulent waves across the view -- I turned the fan off and it seemed to improve.  It makes me think I should change the fan orientation to draw out of the tube from the bottom rather than blowing across the mirror.]

14H 14M 50.85S +10° 06' 02.2" P.A. 111 SEP 0.8 MAG 5.44,8.43 SP K1III DIST. 81.23 PC (264.97 L.Y.)

STF 1877, Izar: Yellow-orange and blue, very pretty, as always

STF 1884: Orange-white, 3 delta mag, ~5"
14H 48M 23.37S +24° 22' 01.0" P.A. 55 SEP 2.1 MAG 6.58,7.48 SP F8IV-V DIST. 84.67 PC (276.19 L.Y.)

STT 582: Very wide blue to east?  Two possible pairs [I did see the AB; there are three stars in all]
14H 34M 40.81S +29° 44' 42.4" P.A. 85 SEP 215.3 MAG 4.5,10.66 SP F2V DIST. 15.83 PC (51.64 L.Y.)

HJ 2728: Wide blue faint B to bright orange A.  PA to west, 4-5 delta mag.  The B was a smudge at first but resolves to disk with seeing.
14H 31M 49.86S +30° 22' 16.1" P.A. 345 SEP 34.7 MAG 3.58,11.5 SP K3III DIST. 49.09 PC (160.13 L.Y.)

STF 1854: Is it triple?  Bright blue-white A, seems to have a pair in the west part of the diffraction.  Another wide separated star to the south, needed AV to notice it. [The diffraction was likely just scattering as there is no close pair, seems I saw AB but the PA is off.  There is a fainter AC]
14H 29M 49.66S +31° 47' 28.2" P.A. 256 SEP 25.6 MAG 6.05,10.62 SP A0VS DIST. 110.13 PC (359.24 L.Y.)

Anonymous to north of STF 1854: Also a faint B to the brighter A, wide separation

STF 1850: Wide yellow-white, 1 delta mag.
14H 28M 33.29S +28° 17' 25.9" P.A. 261 SEP 25.4 MAG 7.11,7.56 SP A1V+A1V DIST. 349.65 PC (1140.56 L.Y.)

STF 1816: A is rod-shaped equal white.  Very faint blue to west, wide separation.  {Woohoo!  First sub 0.5" separation seen from home -- and beats one I saw at Fremont Peak with the 20-inch!]
14H 13M 54.63S +29° 06' 19.5" P.A. 98.3 SEP 0.39 MAG 7.43,7.75 SP F0+A2 DIST. 113.38 PC (369.85 L.Y.)

Antares: I have long wanted to split this but have never been able to.  Using wratten 38A blue filter, the apodizing mask, 277x, I was able to get Antares to a small dot.  I suspected a brighter arc in the diffraction but this is likely scatter -- the pair is separated enough the B disk should resolve.  But it did not.
