Posted: 14 October 2016

On Wednesday, 12 October 2016, a narrow band of clouds came through from the west coast. Did not open the observatory that night. Thursday, 13 October, was clear.

Open: Thursday, 13 October 2016, 1816 MST
Temperature: 88°F
Session: 1022
Conditions: Clear

Equipment Used:
12" f/8 LX600 w/StarLock
Wireless AutoStar II handset
2" 24mm UWA eyepiece
1.25" Binoviewers 20mm

iPhone 6s Plus
D7200 DSLR

After opening the observatory I added some rubber caps on the pier floor bolts:


1826 MST: LX600 ON, StarLock OFF, High Precision OFF.

1830 MST: viewed the planet Venus, 102X. Gibbous phase visible. Next, viewed the planet Saturn, 102X. The moons Titan, Rhea, and Dione were visible. A minute later the moon Tethys became visible. Then viewed the planet Mars, 102X. Although the disk was small, a prominent dark surface feature was visible near the center of the planet's gibbous disk. 1844 MST: viewed the planet Neptune, 102X. A small pale blue disk was visible. Then viewed the planet Uranus, just rising over the hill to the east, 102X. Its disk was larger but was a paler blue.

1848 MST: viewed the waxing gibbous Moon, 102X. It was pretty and bright.

Then began setting up to photograph the Moon projected onto the observatory dome using the iPhone 6s Plus. I mounted the iPhone with a clip-on fisheye lens on a GorillaPod and placed the camera on the observatory floor by the door. Used NightCap Pro (Long Exposure, Light Boost, ISO 4000, 1/3sec, 8 seconds exposure) and the Apple Watch (remote shutter release and remote viewing aid) for this photo:


I moved the iPhone to a better location on the floor to capture the Moon on the observatory dome. This photo is with NightCap Pro (Long Exposure, Light Boost, ISO 8000, 1/3sec, 19 seconds exposure)


1925 MST: next I set up for lunar imaging with the 12" telescope. Mounted the D7200 DSLR at prime focus + focal reducer. This is a 1/640sec, ISO 200, exposure with the color saturation enhanced:


1931 MST: ended imaging. Did some lunar observing using the William Optics Binoviewers, 122X. The view was wonderful. Using binoviewers is a great way to observe the Moon.

1942 MST: last look at the Moon, 102X.

Close: Thursday, 13 October 2016, 1953 MST
