imaged HD 350461 (Halifax)

The BGO robot imaged HD 350461 for me. A double star in Sagitta.

double star HD 350461 luminance

Luminance only, 6 seconds subexposures, 10 stacked shots. FITS Liberator, Paint.NET. North is up; left is east.

There's the kite-shape off to the right (west) with multi-star system HD 186224... That I had first viewed a year ago and then imaged last month.

I tried to tease out the B star from the image but dramatically "unstretching" it in FITS Liberator but I could not spot it...

SkyTools shows, in the charts, an equally bright star about 5" away to the north-west. The Object Information box says, however, the B star is very faint, at mag 13. The WDS reports a similar magnitude.

The weird thing is I can see GSC 01606-1607 due west at mag 13.8. I can see J194251.3+173058 tot the north-west at mag 15.1. And then I can see J194252.4+173053 and J194251.9+173043 both of which are in the mag 17 range!

Where the hell is HD 350461 B?
