captured mu Aql (Halifax)

First viewed μ (mu) Aquilae in August last year, most recently on 31 Aug '18. Spotted most of the elements of the multi-star system but wasn't sure about the D partner.

With BGO, captured the target aka Burnham 653 by centring on the nearby star GSC 00490-3800.

multi-star system mu Aql in luminance

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

The B and C stars at the obvious tight faint pair to the north-east, vertically oriented. D is easy, inline with B and C, further north. Brighter than B and C. To the north-east, the rather bright star, that's E. And P is the faint star due north of A, on the diffraction spike, between C and E. P looks to be the same magnitude as B and C.

Busy field.
