2005 MST: I went back inside the observatory. Viewed M42 (Orion Nebula), 102X. More nebulosity was now visible in the darker sky. However, M42 was low in the sky.
2010 MST: High Precision ON.
Viewed NGC3621 (galaxy), 102X. Supernova 2024ggi was still visible.
2017 MST: I noticed that the Zodiacal Light was visible in the western sky.
Mounted the D850 DSLR at prime focus, focused on the star Minkar, and locked the primary mirror.
