imaged NGC 6210 (Halifax)

A clear night over Nova Scotia triggered my imaging run. The Burke-Gaffney Observatory robotic telescope completed three captures. First up, the Turtle, or NGC 6210, a planetary nebula in Hercules. One of the RASC Finest NGCs. These things are bright! Good round stars in this image.

RASC Finest Turtle planetary nebula luminance

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


Wow. There are a bunch of faint fuzzies in this image... Katrina, using Starry Night and her tablet tried to help me tag them.

Near the top-left corner (that's north-east) are two LEDA/PGC galaxies, both identified by SkyTools. The northern one is, a small oval, LEDA 1696456 and the southern LEDA 1695920. It looks a bit deformed.

Left of the planetary nebula is an extremely faint face-on object. None of our apps labelled this. I had to use Aladin with the NEDS layer. SDSS J164456.12+234621.6.

Near the bottom-left, close to the edge of the frame, is LEDA 1690678, a long thin oval.

Beside the bright star at the bottom left but still close to it is a canted galaxy. It is GALEX J164504.3+234221.

Finally, bottom, right at the edge, centre of the frame, another canted galaxy: GALEX J164420.2+233641.


Found the Turtle in my View Again list in SkyTools. I removed it.


Imaged again, 1/3rd the exposure time.
