returned to HD 194192 (Halifax)

The BGO robot imaged HD 194192 aka HJ 1510. A multi-star system in Cygnus. I had first viewed the 6-star grouping from the CAO recently, on 23 September, but had not spotted the C companion.

multi-star HD 194192 in luminance

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

A is at the centre of the compact grouping. B is to the south-east, close, tight, and almost the same brightness. C, which eluded me before, is very dim, opposite B, to the north-west, slightly further away. D is further north-west, quite bright. E and F are opposite again, in the same direction as B, to the south-east, a pair in their own right. E is the brighter attendant to the north-east; F is slightly dimmer. E is brighter than D; F is dimmer.
