Moon, Crater Gassendi, Visitors
Posted: 29 May 2015
The sky was cloudy on Wednesday, 27 May 2015, but mostly cleared on Thursday.
Open: Thursday, 28 May 2015, 1817 MST
Conditions: Mostly clear
When I opened the observatory I discovered that the thermometer I have in the POD had failed. The temperature noted above is from the LX200-ACF (which can show the ambient temperature).
1824 MST: viewed Venus, 83X. Then Jupiter, 83X and 222X. Slewed to the Moon and viewed it at 83X.
1829-1837 MST: returned to the house to swap the thermometer battery. Still no display on it.
1842 MST: thin cirrus clouds were now in much of the sky. Satellite image showed a thicker band of clouds heading my way.
1843 MST: took this handheld iPhone 5s afocal 83X photo of the waxing gibbous Moon 44 minutes before local sunset:
I noticed I had a curious visitor:
1920 MST: the western sky was getting colorful:
1927 MST: sunset. Still a lot of cirrus clouds in the sky. Took this handheld iPhone afocal 83X photo of the Moon through some thin cloud:
1931 MST: began doing lunar observing, 222X. Seeing was not great (clouds). Crater Gassendi looked interesting at the terminator. Handheld iPhone afocal 222X (cropped):
Had another visitor:
1944 MST: viewed Jupiter, 222X. The South Equatorial Belt looked healthy again this night (unlike on a session a few nights ago). Four moons visible.
1953 MST: decided to close due to the clouds.
Close: Thursday, 28 May 2015, 2005 MST
Temperature: 77°F (telescope)
After I got to the house I did some cleaning of a contact in the thermometer to remove some corrosion. That fixed the problem and the thermometer began working again.
