2030 MST: back in the observatory to begin some observing. I first did the AutoStar Tour "Tonight's Best", 102X: NGC3115 (Spindle Galaxy), NGC3377 (galaxy), NGC4261 (galaxy), M68 (globular cluster), Centaurus A (galaxy), M51 (Whirlpool Galaxy), M13 (Great Globular Cluster in Hercules), M92 (globular cluster), and M57 (Ring Nebula). I also viewed M65/M66/NGC3628 (Leo Triplet of Galaxies), M64 (Black Eye Galaxy), M61 (galaxy), M104 (Sombrero Galaxy), M87 (galaxy), and Omega Centauri (globular cluster), 102X. It was fun just spending time observing Deep Sky Objects.

2115 MST: sighted Omega Centauri (globular cluster) very low in the southern sky, naked eye. Then used 12x50 binoculars to view it.

Next, viewed M4 (globular cluster) and M10 (globular cluster), 102X.
