Three Globular's and an Open Cluster

Recommended Posts

Between the weather and dealing with family issues, last night was my first opportunity to get out in the past month.
I managed to capture these three globulars and one open cluster from the Redstone Trailhead in the Lake Mead National Recreation Area. SQL Reading 45 minutes after the crescent moon set was 21.16. Temp was 86°f (30°c) at the reading time but dropped to 72°f (22.2°c) by 3:30am local time when I wrapped up the session.

Details are identical for all images.
