almost robo

I successfully connected to the servocat from my laptop, and when doing a normal goto from the Argo Skytools showed it was slewing...but the Argo was not sending the telescope position to Skytools, so I was unable to use Skytools to slew.  I modified the driver set-up slightly (to stop the J2000 translation) -- so we'll see if this works.  Otherwise the frustration continues.

Star hopped again to various doubles.  Seeing was not very good, even with the 8" mask.  And the moist marine haze continued -- a very fine mist in the air which I could smell.

STF 2523: 8" 205x. Near equal white, well separated. Near the Coat Hanger, which I viewed through the finder. [AB]
19h 26m 48.38s +21° 09' 46.2" P.A. 148 sep 6.4 mag 7.95,8.05 Sp B3V+B7V dist. 1470.59 pc (4797.06 l.y.)
STF 2504: 8" 205x. Yellow and slight orange, 1.5 delta mag, well separated.  In line with a 3rd star very widely separated. [Third star not part of the system]
19h 20m 59.85s +19° 08' 43.4" P.A. 282 sep 8.6 mag 7.00,9.03 Sp F5V dist. 62.7 pc (204.53 l.y.)

BU 139: 8" 667x: At the very best moments of seeing, which were fleeting, saw kissing disks to hairline split.  Suspected elongation at 205x & 333x.
19h 12m 34.45s +16° 50' 47.2" P.A. 135.9 sep 0.59 mag 7.11,7.95 Sp B9IV dist. 242.72 pc (791.75 l.y.)

STT 368: 8" 333x. Very fine 1 delta mag, ~1" split, white. [AB. AC 13.2 mag not seen]
19h 16m 01.84s +16° 09' 39.5" P.A. 219 sep 1.1 mag 7.53,8.49 Sp A9IV dist. 240.96 pc (786.01 l.y.)

STTA 178: Wide finder split, yellowish A, ~1 delta mag. 8" 333x
19h 15m 20.09s +15° 05' 01.2" P.A. 268 sep 89.6 mag 5.69,7.64 Sp G8II-III dist. 212.31 pc (692.56 l.y.)
STF 2489: White with reddish B, 3 delta mag, wide split. 8" 333x
19h 16m 26.78s +14° 32' 40.6" P.A. 347 sep 8.3 mag 5.67,9.30 Sp B9.5V dist. 125.63 pc (409.81 l.y.)

Ho 91: FF Aql. 20" 333x: Orange star, but no pair seen at 8".  Removed the mask to 20", and voilĂ , a faint, small point, reddish, well separated, appears.  Mask back on, and I think I can barely see the B star with averted vision, but only knowing where it was first -- and only marginally.
18h 58m 14.75s +17° 21' 39.4" P.A. 146 sep 7 mag 5.44,10.12 Sp F8II dist. 473.93 pc (1545.96 l.y.)
