After opening the observatory I set up the Nikon D7200 DSLR with a Tamron 150-600mm lens on the observatory patio:


1814 MST: LX600 ON, StarLock OFF, High Precision OFF.

1816 MST: viewed Venus in the 12" telescope, 102X.

Went to the D7200 DSLR and took this f/11, 1/1000sec, ISO 400, FL 600mm photo of Venus and some clouds. The inset shows a magnified version of Venus from the same photo:


The nearly Full Moon was visible in the eastern sky so grabbed this photo with the D7200 DSLR, f/11, 1/800sec, ISO 400, FL 600mm:


The scene from the observatory patio was pretty, with some sunset clouds in the western sky and the Moon in the eastern sky. Used the iPhone 6s Plus for this panoramic photo:
