quickly loaded HD 177904 (Halifax)

When the BGO 'bot reported an empty queue, I quickly sent in an entry found in SkyTools from Coldfield. Sounds like a colourful system in Aquila. HD 177904 or STF 2449.

double star Struve 2449 in luminance

Luminance only, 1 second subexposures, 12 stacked shots. FITS Liberator, Paint.NET. North is up; east is left.

A very tight doublet nearly oriented east-west. The left or east sun looks brighter to me, by a hair.

[ed: Haas says it is a binary.]

Will have to wait for the colour version...
