Found
on first try at 80x, sky still dark blue. Primary seemed yellow, but that
might be the result of the sky color, secondary seemed blue. Measured with
the video at prime focus. The images were spread into N/S ovals due to
atmospheric refraction at such low elevations; separation 10.5
sec, 031 deg PA.
More comments: h4902 and BU127 were not observed previously due to the southern declination and my continuing tree problem to the south. But, there is a small gap between the house and the tallest trees that amounts to about 45 minutes of possible time to catch these stars. Only problem is that it would be possible only during twilight, which last to 11:20pm at this time of year. Solution, setup at 10pm and align the setting circle on Antares when it becomes visible then move to the correct coordinates and wait. Success, both were found during the time window and were visible in the deep twilight.
