After preparing the equipment for this night's ZWO Atmospheric Dispersion Corrector (ADC) imaging tests I relaxed on the observatory patio bench.

1912 MST: sunset. This was the view of my SkyShed POD observatory from the bench.


1930 MST: LX600 ON, StarLock OFF, High Precision OFF.

Viewed the planet Jupiter, 102X. The four Galilean Moons were visible. This handheld iPhone afocal 271X photo was taken using the iOS app NightCap Camera (ISO 160, 1/3sec) and shows the moons (and the overexposed planet):


2011 MST: the nearly Full Moon began rising over the hill to the southeast. The Moon was about 9 hours before precisely Full. There were clouds in the southern sky which were hampering my ADC imaging tests.

2026 MST: ended the ADC tests. I hope to get my review posted soon.

2033 MST: viewed the planet Saturn, 102X. There were five moons visible.

Then viewed the Moon through a tree, 102X. A slight terminator was visible. Switched to 49X for viewing of the Moon.

2047 MST: the southern sky taken with the D850 DSLR, f/1.4, 1/5sec, ISO 3200, FL 50mm, handheld:

The photo shows the planets Saturn and Jupiter, the star Antares, the constellations of Sagittarius and Scorpius, and some clouds against the moonlit sky.

2055 MST: the Moon was coming out from behind the tree. Unfortunately it was now being obscured by clouds, as seen in this handheld iPhone afocal 49X photo:


As the prospects for clearing were diminishing I decided to close up for the night.

2105 MST: LX600 OFF.

Close: Wednesday, 14 August 2019, 2113 MST
Temperature: 85°F
Session Length: 2h 28m
