captured curious NGC 7510 (Halifax)

There seems a dearth of Finest NGC targets at the moment. That is, for me to capture. With SkyTools, I looked up some interesting objects. NGC 7510. A compact open cluster in Cepheus. The queue was nearly empty so the BGO 'bot tagged it quickly. Neat! I get a strong sensation of motion, that this gaggle of stars is zipping through space. "Follow me!"

Luminance only, 30 seconds subexposures, 10 stacked shots. FITS Liberator, Paint.NET. North is up; left is east.

To the north-east of the cluster, half-way to the top-left corner, is an obvious double star. A tight pair with a bright primary and dim secondary. This is HD 240221 aka STI 1150.

There is, obviously, another pair of stars, further up. Very similar to the HD star. A different position angle, a dimmer second star, almost the same separation. But this does not appear to be an official double. At least SkyTools does not show it as such. HD 240227 and GSC 04279-2369. Huh. [ed: Nothing in the WDS.]
