Easy to split with nice distance and obviously unequal. A conspicuous group of fainter stars is nearby. Main component appeared in a warm-white, fainter somehow darker (partly bluish, partly slightly orange).

55mm f/9.1, 38x, Bortle 6-, SQM-L 19.1
At 38x split, but very tight with noticeable difference in brightness. At 56x and higher beautiful view of both components, which seemed to have similar colors.
|
|
55mm f/9.1, 59x, Bortle 6, SQM-L 19.5
Very nice unequal double. A appeared yellow-orange, B rather white-bluish.
|
|
70mm f/5.7, 100x, Bortle 6-
At 67x still a relatively close pair, but well separated with quite a clear difference in brightness. At 100x easy to separate and visible color difference: A yellowish to slightly orange, B white-yellowish.
|
|
120mm f/5, 66x, Bortle 6-, SQM-L 19.1
At 48x easily seen as double star. It appeared as '8'. At 66x pretty tight with visible difference in brightness.
