received NGC 2539 data (Halifax)

I asked BGO to image NGC 2539, aka Collinder 176, for me. A loose open cluster in Puppis. One of the RASC Finest NGCs.

RASC Finest open cluster NGC 2539 in luminance

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

This image isn't quite centred the way I had hoped.

There's a neat multi-star system to the south-east of the cluster. But it's cut-off on the left edge of the frame. Maybe I'll reshoot, using a specific star, to force the star system to be included...


Reframed on 9 Jan.
