zoomed on the ring (Halifax)

I asked the Burke-Gaffney Observatory to image the Cygnus Fairy Ring—for fun. A rather large ring of faint stars, many pairs of stars, roughly between γ (gamma) and η (eta) Cygni.

Perhaps not the best subject for BGO as barely fits on the reduce sensor frame. The effect is not as striking as I had hoped. And a couple of the doubles are out of the view.

Luminance only, 15 seconds subexposures, 10 stacked shots. FITS Liberator, GIMP. North is up; east is left.

Centred on GSC 03150-1379.

North of centre, near the top of the frame, slightly left is the obvious bright pair. However the bright stars are not considered the double star proper. Close and south-south-east of HD 190628 is the much dimmer companion. This couple is also known as PAN 17.

North-west of centre, near the top-right corner, is another bright pair. This time the two stars are related. This is HD 190466 aka HJ 1470.
