NGC 3312 Cluster

Click image above to view full size
This may not be a cluster as officially designated, but it is astunning field of galaxies.

Visible in this image is 14 galaxies: NGC 3312, NGC 3311, NGC 3309, NGC 3316, PGC 155483, PGC 753342, PGC 753354, PGC 31542, PGC 141487, PGC 753828, PGC 141485, PGC 141483, PGC 31476, PGC 141484!

The image has been slightly enhanced to darken the background and brighten the galaxies, as such the galaxies brightness relative to the visible stars is not 100% accurate, but is close.

You might be surprised at the brightness of PGC 141483 at Mag 18.6. It looks bright because of a foreground star infront of it.

The image doesn't exhibit wonderful quality, the sharpness is ok considering the image scale (0.86 arc sec/pixel) but not great.

Visible in the original exposure is stars down to magnitude 20.8. Because of adjustments to make the image "look nice" these fainter stars aren't showing.

Because of the faintness of some galaxies in the final image, depending upon your monitor settings you might have trouble seeing some.
