70mm f/5.7, 100x
2020-04-01: Separable at 67x, but difficult due to the bright primary component. Clearly separable at 80x and higher magnifications with a significant difference in brightness. The companion stands close to the primary component and appears as a tiny star. Nice view.

120mm f/5, 168x, Bortle 7+, NELM 5m0, SQM-L 18.8
At 50x elongated, at 75x seen as '8'. At 168x clearly split with obviously fainter component.

Robert Zebahl
120mm f/5, 50x, Bortle 7+, NELM 5m0, SQM-L 18.8
At 50x split with little distance. At 75x clearly split with small difference in brightness.

STF 1459 (**)

Clearly split with noticeable difference in brightness.

STTA 104 (**)

Name: STTA104
Type: **
Constellation: LMi
Coordinates: 10h24m22.19s / +34°10'35.00"

Components:

70mm f/5.7, 22x, Bortle 6
2020-04-11: Very wide pair of similarly bright components, unremarkable color. The double star stands close to the stars 27, 28 & 30 LMi and is probably more appealing in smaller binoculars.
