About this image

A very massive cluster at 2.2 billion L yrs, well known for gravitational arcs seen in images by Hubble ST - though not detected in these frames. Field of view 31x31min arc.

The images received are dark and flat corrected with astrometric calibration. Deep Sky Stacker was used to combine them, with a histogram stretch in AstroArt 5.

I was interested to see how deep i could go with a 60cm in 10min, The brighter members of the cluster are roughly 17th mag without checking catalogs.
