iPhone 5s: Lunar Straight Wall

Posted: 10 March 2014

Opened: Sunday, 9 March 2014, 1741 MST
Temperature: 72°F
Session: 660
Conditions: Clear, breezy

1749 MST: viewed the moon at 83X using the 8" LX200-ACF. Sky still bright well before local sunset. Took this handheld iPhone 5s afocal photo:


1802 MST: slewed to Jupiter and viewed it using 83X. Sky too bright 27 minutes before sunset to see any of the Galilean Moons. Switched to 222X; low contrast view. Tried adding the 2X PowerMate for 444X, but Jupiter was really too low contrast for viewing.

Returned to the moon and used 444X for a lunar terminator tour. Nice views, especially of the Straight Wall.

1829 MST: sunset.

Took this handheld iPhone 5s afocal 444X photo of the Straight Wall:


1838 MST: switched back to 222X. Took this handheld iPhone 5s afocal 222X photo of the Straight Wall and other portions of the southern terminator:


Then took this handheld photo of the northern portion:


1854 MST: slewed back to Jupiter and viewed it using 222X. The four Galilean Moons were visible. This iPhone 5s handheld photo (cropped) shows the moons (Jupiter is overexposed):

Mouseover or tap to see the moon names

Tried viewing Jupiter at 444X but seeing was not good enough.

Session was ended early so I could watch the new "Cosmos" on TV. I loved the original Carl Sagan "Cosmos" back in 1980 and recently watched it again on DVD.
