There were clouds in much of the sky. Fortunately there was some clear sky as well. This is a view to the south where Jupiter and Saturn would appear once the sky was darker:
1918 MST: LX600 ON, StarLock OFF, High Precision OFF.
1920 MST: viewed Jupiter, 102X. Three moons were visible.
Began preparing the D850 DSLR for imaging of Jupiter and Saturn.
1932 MST: Jupiter, 102X. The Great Red Spot was coming into view. Seeing was not great due to clouds.
Mounted the D850 at prime focus + 4X Powermate + Atmospheric Dispersion Corrector. Took these images of Jupiter (1/80sec, ISO 1600) and Saturn (1/40sec, ISO 5000), both cropped from the full-frame photos.
1949 MST: done imaging.
1953 MST: viewed Saturn, 102X. Three moons were visible.
1959 MST: decided to end the session due to the clouds that were in much of the sky.
2008 MST: took this handheld D850 DSLR photo (f/2.8, 1 second, ISO 5000, White Balance 4000K, FL 24mm) of the southern sky with Saturn, Jupiter, the constellations of Sagittarius and Scorpius, the Milky Way, and some clouds:
