63mm f/13.3, 46x, Bortle 6-, SQM-L 19.0
Clearly split, but tight with noticeable difference in brightness.
|
|
70mm f/5.7, 80x
At 67x pretty tight pair, but separated with a clear difference in brightness. The primary component appeared in a hint of orange. At 80x easy to separate.
|
|
8" f/6, 100x, Bortle 4, NELM 5m.9+, SQM-L 21.0
Conditions in the target region: SQM-L 20.8 Nice double star with big difference in brightness.

B 8x44
AB: 2020-11-25: Easy to split at still quite small separation and visible difference in brightness. The primary component appeared white-yellowish, the companion darker.
|
|
B 12x42, Bortle 4-, SQM-L 20.8
AB: 2022-10-19: Easy to split at moderate separation and small difference in brightness. Well visible color difference, although it is difficult to assign the color to the components: white-bluish & yellow-orange.
|
|
70mm f/5.7, 22x
AB: At 22x widely separated, striking with a rather small difference in brightness. A seemed a bit warmer in color compared to B with a hint of orange. At 44x, both seemed slightly orange with very little difference in color.

70mm f/5.7, 15x, Bortle 6-
Easy to split with large distance and difference in brightness.

René Merting |
12.5" f/4.5, 45x, SQM-L 21.0
bei 45x ein wunderschönes, sehr helles Farbkontrastpaar, A ist gelb-weiß, B im Nordosten ist gut 1.5 Magnituden schwächer und grau-weiß - Trennung mehr als komfortabel

76mm f/7.5, 95x, SQM-L 18.6
AB: bei 57x zeigt B sich südöstlich von A und klebt noch an diesem, die Trennung gelingt dann äußerst knapp bei 95x AC: bei 29x zeigt sich C ganz schwach weit abgesetzt südwestlich von A - Helligkeitsunterschied mehr als zwei Größenklassen

The companion is visible as elongated, non-condensed brightening in the first diffraction ring of the primary component.

René Merting |
76mm f/7.5, 95x, SQM-L 18.6
bei 95x zeigt sich B südöstlich von A, lässt sich allerdings noch nicht ganz trennen - ich habe auch höhere Vergrößerungen probiert, aber dann schlug das Seeing gnadenlos zu und hat keine Trennung zugelassen
