Big! Bright! a spectacular globular cluster in the large telescope, 20' in diameter, a coarse appearance compared to the usual globular cluster mist of faint stars, here I see brighter stars punctuating a relatively sparse population of fainter stars, a moderately concentrated core about 5' in diameter, fully resolved in rich galactic starfield

Large, bright, 20' across, fully resolved, moderately concentrated at the core, stars arranges in many short chains or clumps, quite a nice globular

Large, fairly bright, attractive globular cluster, well resolved at 97x, about 20' in size nicely filling the field, would be a truly impressive sight higher in the sky
