Full Moon give or take. So time to ask BGO to image a double star.
I chose HD 119702 aka HJ 2682 from the Coldfield list. An interesting triple, actually, near the UMi / Cam border. Aimed at GSC 04558-2218.
Luminance only, 2 seconds subexposures, 12 stacked shots. FITS Liberator, GIMP. North is up; east is left.
A is the brightest star in the field. SkyTools 3 Professional says this is mag 6.7.
B is the closer but dimmer star, nearly due west. ST3P says this is mag 9.7. That does not seem right. Hovering in the chart, the magnitude is shown as 10.1. It is at a position angle of 282 degrees and a separation of 25.6 seconds of arc.
C is to the north-west, double the AB separation, brighter than B. The software reports mag 9.0, 318°, 43.8".
I like the serpentine line of equally bright stars to the south-east.
