NGC 6397 Globular Cluster
Captured NGC 6397 a magnitude 6 globular cluster in the constellation of Arae
40 x 2 minute subs
15 x darks
ISO 800
PHD2 guided
Un dithered subs
A small but interesting cluster
Probably should have bumped up the ISO to 1600 as the histogram was less than 1/4 and this may have given more detail and a brighter image when stretching the stacked image in Startools
