catching up

I had a session last Friday night which I haven't gotten down yet, so catching up here.  The notes filled the last page of my notebook, which started in August with some sketches of Mars.  Shows how poor the observing season has been, needing six months to fill one notebook.

Seeing was middling, about 5-6/10, and transparency not much better at 3/5.  Using Big Blue, most at 270x unless noted:

HU 1067: Light orange star, small, definitely elongated at 553x.  Seems to resolve in best moments to a very faint B star, but uncertain.  Very faint in the finder, at its limit.
03H 49M 36.35S +38° 58' 55.5" P.A. 77 SEP 1.3 MAG 9.72,10.56 SP A2IIV: DIST. 467.29 PC (1524.3 L.Y.)

STF 500: 1 delta mag, ~4", very hazy. 553x
04H 11M 41.62S +40° 15' 54.7" P.A. 79 SEP 3.9 MAG 8.84,10.70 SP G0

Atik = STF 464AB: Triple system, 2 very faint stars nearby.  270x [Did not see BU 535 1.1" 3 delta mag; the second star I saw not in system]
03H 54M 07.92S +31° 53' 01.2" P.A. 209 SEP 12.9 MAG 2.86,9.16 SP B1IB DIST. 230.41 PC (751.6 L.Y.)

Anonymous between Atik and BU 535: Very close & faint B 3 delta mag.  Tough with 270x

BU 535: No split at 270x seeing not steady
03H 44M 19.13S +32° 17' 17.7" P.A. 20 SEP 1.1 MAG 3.91,6.70 SP B1III DIST. 343.64 PC (1120.95 L.Y.)

40 Per: Wide, 2 delta mag, white-yellow and very faintly blue
03H 42M 22.64S +33° 57' 54.1" P.A. 244 SEP 19.8 MAG 4.97,10.04 SP B1.5IV DIST. 323.62 PC (1055.65 L.Y.)

BU 533: Overlapping yellow-orange disks, equal mag, at 270x!
03H 35M 37.81S +31° 40' 48.7" P.A. 220.7 SEP 1.02 MAG 7.55,7.74 SP F4V DIST. 85.98 PC (280.47 L.Y.)

Tok 13 = UX Ari: Orange star with very faint wide blue B?  I seem to also see a much fainter star in a near line in between these two. [Likely the wider star...  also has CHR 9 0.4" 3 delta mag, would be good to try with the 20-inch]
03H 26M 35.36S +28° 42' 55.2" P.A. 129 SEP 96.4 MAG 6.59,10.00 SP G5IV-V DIST. 51.63 PC (168.42 L.Y.)

STF 401: in the scope equal mag, white, well separated.
03H 31M 20.76S +27° 34' 18.5" P.A. 269 SEP 11.4 MAG 6.58,6.93 SP A2V DIST. 97.47 PC (317.95 L.Y.)

STFA 7: Nice finder split, equal mag but faint, ~8th mag.
03H 31M 03.47S +27° 43' 53.6" P.A. 234 SEP 44.1 MAG 7.41,7.81 SP B9 DIST. 120.05 PC (391.6 L.Y.)

STF 427: Near equal mag, white and fainter B is yellow, well split.
03H 40M 38.77S +28° 46' 24.0" P.A. 207 SEP 7 MAG 7.41,7.84 SP A1V+A2V DIST. 113.12 PC (369 L.Y.)

STT 77: Finder triple. [Not likely seen, AB is 0.5"; may have just been a near equal field star]
04H 15M 55.73S +31° 41' 35.1" P.A. 316 SEP 132 MAG 7.48,9.57 SP G0V DIST. 101.52 PC (331.16 L.Y.)

STT 81 = 56 Per Pretty yellow and slight red pair, 2 delta mag.
04H 24M 37.46S +33° 57' 34.9" P.A. 13 SEP 4.2 MAG 5.84,9.25 SP F4V DIST. 40.62 PC (132.5 L.Y.)

STF 533: Finder split, fairly wide, 1 delta mag; wider in scope.
04H 24M 24.85S +34° 18' 53.1" P.A. 61 SEP 20.2 MAG 7.30,8.49 SP B8V DIST. 221.73 PC (723.28 L.Y.)

14 Aur = STF 653: Triple, one of which is one delta mag fainter than the other equal pair.  All well separated.  [AC is the brighter pair; AB fainter.]
05H 15M 24.39S +32° 41' 15.3" P.A. 11 SEP 9.8 MAG 5.03,10.90 SP A9IV DIST. 87.57 PC (285.65 L.Y.)

STF 648: Light orange, half delta mag, wide. [AB seen, three other pairs too faint]
05H 10M 59.19S +32° 02' 19.5" P.A. 62 SEP 4.7 MAG 8.14,8.93 SP G5 DIST. 42.44 PC (138.44 L.Y.)

STT 61: Finder split, 1 delta mag. [Not seen, likely just a field star; separation too close for finder]
03H 42M 45.91S +07° 54' 10.6" P.A. 128 SEP 1.4 MAG 7.77,10.63 SP A2 DIST. 127.55 PC (416.07 L.Y.)

STF 645: White and grey, 2 delta mag, wide. [A,BC seen.  BC good for the 20-inch, BU 1047 0.3" near equal]
05H 09M 45.06S +28° 01' 50.2" P.A. 29 SEP 11.3 MAG 6.04,9.11 SP A5M DIST. 52.6 PC (171.58 L.Y.)

Bgh 21: Yellowish-white star.  Suspect a close-in B but the pairing might be the faint, very wide star seen in the scope and finder. [for sure the wide star]
05H 10M 03.87S +27° 33' 23.4" P.A. 353 SEP 314.6 MAG 7.02,9.27 SP F5+G5 DIST. 40.03 PC (130.58 L.Y.)

M37: After a while of searching, used the 31mm for 87x view in the scope.  Carbon star at the edge of the field.  Duller than I remember, transparency hurting the view.
