captured HD 151367 (Halifax)

BGO imaged HD 151367. aka Σ2098. A multi-star system in Hercules. When I first observed this target in August 2014, I had not successfully split the D and S elements. No problem in this image (but you'll have to zoom in).

Luminance only, 3 seconds subexposures, 10 stacked shots. FITS Liberator, Paint.NET. North is up; east is left.

A, the primary, is the brighter star of the tight pair, to the north.

B is the slightly dimmer star to the south-east.

C is further in the same direction, south-east, 5 or 6 times the distance. It looks to be the same brightness as A.

D is north of A, slightly to the east, dimmer than B.

The elusive S companion is visible to the west of D. Much fainter. Very tight, practically touching D.
