beautiful doubles in UMa

Monday night had a window of relatively clear skies, and surprisingly good seeing.  I used Big Blue to chase down some close / wide delta mag doubles in UMa, and totally enjoyed the night -- I really needed it!

23 UMa / STF 1351: 270x.  Lovely yellow-white and 3x fainter wide B, white.  A third star further out. [It is a triple system, but since AC is 11th mag, did not see that.]
09H 31M 31.57S +63° 03' 42.5" P.A. 268 SEP 22.9 MAG 3.65,9.19 SP F0IV DIST. 23.82 PC (77.7 L.Y.)

Tau UMa / H V 75AB: 270x.  Very wide; A a light yellow orange.  Pretty.  [Did not see the true pair, which is also 11th mag.]
09H 10M 55.05S +63° 30' 49.0" P.A. 36 SEP 52.1 MAG 4.68,11.42 SP AM DIST. 38.73 PC (126.34 L.Y.)

For the rest of the night, at 553x:

Arg 21: Two very faint stars, wide separation, ~0.5 delta mag, to south of an orange star.  Roof currents affecting the seeing. 
08H 55M 51.01S +64° 58' 21.6" P.A. 107 SEP 21.4 MAG 10.01,10.45 SP G0

BU 408: !! BU 408 is the fainter star in a pair pair of near equal stars in finder view, red-orange color.  In the scope the B is a blue star 3" out from the orange star.  Seen as near perfect disks.
08H 59M 00.62S +63° 25' 42.8" P.A. 344 SEP 2.8 MAG 7.35,9.59 SP G5 DIST. 196.46 PC (640.85 L.Y.)

STT 199 / 37 Lyn / Arn 71: Yellow with very faint wide reddish B, ~4 delta mag.  Seen in same field with 37 Lyn, which I think is the STT 199 star, which is brightest, paired with the next brightest star wide separation.  Arn 71 I think is the faintest star making an equilateral triangle with the other two.
STT 199 = 37 Lyn; AB: 09H 20M 43.76S +51° 15' 57.8" P.A. 138 SEP 5.6 MAG 6.19,10.00 SP F5V DIST. 27.45 PC (89.54 L.Y.).  AC is 10.66 mag and 128.4".  Arn 71 is AD, 7.89 mag and 231" -- so I had 37 Lyn and Arn 71 reversed in my description above.  An interesting system!  Galaxy NGC 2841 is just below Arn 71, but I could not see it in the light pollution -- the STT 199 system is the trio of stars in the upper right corner of this image]

STT 200: !! Light orange A, B a deeper orange, maybe because it's 2-3x fainter.  B resolves from within A's diffraction when seeing settles, ~1".  Wow!
09H 24M 55.67S +51° 34' 26.1" P.A. 337 SEP 1.2 MAG 6.53,8.57 SP G0IV DIST. 129.2 PC (421.45 L.Y.)

STT 209: ! Light orange-yellow disk with faint diffraction ring.  Extremely faint blue B ~4"; can see it direct vision but it flashes forth with averted.  10th magnitude seems to be the limit tonight (transparency 3/5)
09H 53M 17.23S +50° 37' 16.3" P.A. 309 SEP 4.9 MAG 7.41,10.31 SP G8IV DIST. 196.85 PC (642.12 L.Y.)

Had a look at high proper motion star Groombridge 201 through the finder, and made a quick sketch.

STT 210: !! Yellow A and white B, very tight.  Faint, seeing needs to be perfect to see B in the diffraction. 
10H 02M 35.64S +46° 21' 42.5" P.A. 256 SEP 1.2 MAG 8.52,9.07 SP G5 DIST. 228.83 PC (746.44 L.Y.)

Cbl 38: Three stars in a row, middle is the brightest; one closer is 1 delta mag, the second on the other side is 1.5 delta mag. [Likely did not see, though it could have been the fainter, more widely separated star.]
09H 50M 29.75S +45° 05' 01.3" P.A. 11 SEP 53.1 MAG 7.46,11.71 SP F3VN DIST. 101.42 PC (330.83 L.Y.)

STF 1491: Orange and blue, pretty wide, ~3 delta mag.  [AB seen; AC 14.9 mag, FYM 406]
10H 58M 50.42S +61° 42' 56.4" P.A. 30 SEP 14 MAG 8.39,11.33 SP K0 DIST. 1052.63 PC (3433.68 L.Y.)

STF 1512: Pretty near equal bluish-white stars
11H 09M 13.09S +62° 29' 51.0" P.A. 52 SEP 10 MAG 9.29,9.52 SP A2 DIST. 448.43 PC (1462.78 L.Y.)

STF 1469: White and 2x fainter B, wide.
10H 47M 43.86S +65° 27' 36.4" P.A. 324 SEP 10.6 MAG 7.74,10.42 SP F8V DIST. 86.88 PC (283.4 L.Y.)

ES 1905: White with 3x fainter, 11th mag, B.  Very wide.  How suspect it was binary? [AB seen.  BC would be a challenge for the 20-inch, 11.6/13.4, 3.9"]
10H 30M 16.09S +63° 20' 55.4" P.A. 67 SEP 42.4 MAG 8.59,12.64 SP K0 DIST. 226.24 PC (737.99 L.Y.)

STF 1407: Near equal faint 10th-11th mag white stars, 4"
10H 09M 01.98S +64° 26' 40.6" P.A. 51 SEP 4.9 MAG 10.17,10.63 SP K7 DIST. 176.06 PC (574.31 L.Y.)

STF 1398: Near M81 & M82!  Did not see the 11th mag, 3" B star, tried really hard.  To the south is a tight = red pair. 
10H 01M 32.06S +68° 43' 05.1" P.A. 103 SEP 3.1 MAG 8.09,11.39 SP F0 DIST. 159.24 PC (519.44 L.Y.)

STT 233: White with 3-4x fainter B, well separated.  ~10th mag.  Seeing needs to still.  [AB seen; AC 12th mag 38"]
11H 18M 46.75S +66° 41' 03.3" P.A. 333 SEP 4.7 MAG 7.16,10.20 SP A8IV DIST. 124.38 PC (405.73 L.Y.)

STF 1514: Extremely fine!  It is at the base of a kite asterism, the fainter star of four; the three arcing the top of the kite are equal magnitude.  STF 1514 is a very tight 1.5" but clean split, 1 delta mag.  Nice!
11H 11M 38.55S +66° 06' 48.0" P.A. 344 SEP 1.4 MAG 9.49,10.64 SP F2

STT 222: Extremely faint star, B seen with averted vision, PA to north. 
10H 38M 19.89S +60° 07' 30.1" P.A. 336 SEP 4.3 MAG 7.00,11.70 SP F8 DIST. 75.41 PC (245.99 L.Y.)

STF 1519: !! 1 delta mag, tight 1.5" faint yellow stars.
11H 15M 36.65S +59° 46' 43.4" P.A. 290 SEP 1.4 MAG 9.03,9.95 SP F5 DIST. 250.63 PC (817.56 L.Y.)

STT 235: !! Nice!  Yellow and orange, 1.5 delta mag, split when seeing shows perfect disks.  The stars both show albedo effects, look like suns / globes with shadowing. 
11H 32M 20.76S +61° 04' 57.9" P.A. 39.7 SEP 0.92 MAG 5.69,7.55 SP F8V DIST. 27.99 PC (91.3 L.Y.)
