imaged Struve 2902 (Halifax)

An hour and a half after starting up, the Burke-Gaffney Observatory imaged double-star HD 212468 aka Σ2902 in Lacerta. It is a beautiful but tight double from the Coldfield 200 list.

Luminance only, 5 seconds subexposures, 20 stacked shots. FITS Liberator, Paint.NET. North is up; east is left.

A and B are nearly the exact same brightness. Very close. Touching in the image. SkyTools 3 Pro says the separation is 6.5 seconds of arc. Lovely.

Bonus double star? Included in this image, to the extreme north, at the top edge of the image, is the fantastic unequal pair of BD +44 04117 aka ES 104. The very faint B partner is north of bright A.
