70mm f/5.7, 22x
At 22x and 57x the components A, B, E and F were easily seen. The B component appeared slightly bluish-silver at 22x, but at 57x the color was difficult to tell. All four components form a slightly curved 'Y' with the bright A component in the center.

Striking, especially with STF 2474 in one visual field. The color of the components was not clearly visible. Worthwhile! Sketch see STF 2474.

Pretty conspicuous, easy double star. Especially attractive with the nearby double star STF 2470, as both are very similar in brightness, distance and position angle. The color of both components appeared slightly yellowish-orange.

SHJ282 (AC): Fairly bright and wide pair. The double star was conspicuous, especially in regard to its color: A appeared orange, C rather grey-bluish. It could be observed together with Messier 57 and beta & gamma Lyrae. Very nice.
