Astrophotography targets "come around' annually as they are optimally positioned. This is my second crack at M3, a globular cluster about 14 million ly away in Canes Venatici. Last time I used an unmodified Nikon D90. This year (April 1, 2019), I managed far better resolution with steady seeing and a ZWO ASI183MM camera, shooting at .52 arc seconds/pixel. In fact, I was able to resolve stars right across the face of the cluster. This is 85 minutes of LRGB, 40 flats and library darks, with a 5 " ES127ED apo refractor. Processed in Pixinsight.
