captured HR 6043 (Halifax)

The Burke-Gaffney Observatory imaged HR 6043 aka STT 305. This is a multi-star system in Corona Borealis. I selected it from a "most beautiful" list in SkyTools 3 Pro. The image is centred on GSC 02576-1852 with the target system near the top.

multi-star system HR 6043 in luminance

Luminance only, 4 seconds subexposures, 20 stacked shots. FITS Liberator, Paint.NET. North is up; east is left.

The B attendant is the medium-bright star immediately to the west, very close, almost touching the primary.

While there are many bright stars nearby, they are not noted in ST3P as members of the system. Also there is a dim star to the south-west. Close.

There is a C element. It is further west. In fact, it is in the vertical line of 3 dim stars, being the lowest or southern point.

It is fascinating to spot the dim oval galaxy south of OΣΣ 305 C. This is PGC 57432. It must be bright to appear in a 4 second shot...
