Background
NGC 6544 is a small, relatively bright globular cluster 9,000 light-years away in Sagittarius, 1° south-east of M20. One of the closer globular clusters and notable for its irregular, mottled appearance.
My Observing Notes
25-cm (Meade 10-inch LX200, The Coffee Grinder): Easy to spot in the viewfinder 1° SE of M20. Small (8.9') but relatively bright (mag 8.2), the core appears mottled with some brighter stars resolved. Irregular shape — not the symmetric circular halo of many globulars. Averted vision adds richness to the halo.(Friday, June 2025)
