M53, globular cluster in Coma Berenices.
It is a stack of 4 four minute exposures taken with an SXV-H9 CCD camera
through a Vixen R200SS 8" f/4 Newtonian with a Paracorr.
The images were calibrated, defect-corrected and stacked, and a DDP was
applied with all processing performed using AIP4WIN.
This image has been resampled down from its original size of 1392x1040.
