In previous two observations, I mainly concentrated on open clusters and double stars. So this time, my objective was globular clusters. But I also observed a few OCs and nebulae.

Globular Clusters:

• NGC 5139 (Omega Centauri)
• NGC 5286/Caldwell 84
• M4
• M80
• M10
• M19
• M62
• M9
• NGC 6356

• M12
• M14
• M22
• M24

Open Clusters:

• NGC 4755 (The Jewel Box)
• NGC 5460
• M7 (Ptolemy Cluster)
• M6 (Butterfly cluster)
• NGC 6383
• NGC 6416

Nebula:

• M17 (Omega/Swan Nebula) - very evident in the scope
• M8 (Lagoon Nebula) - not as evident as M17 but still could make out

I also spent some time on observing the Terminator on the Moon. Had to wind up at 12am due to mosquito bites.
