iPhone 5s: Lunar Mare Humorum (again)
Posted: 16 October 2013
Cassiopeia Observatory was opened Tuesday, 15 October 2013, at 1819 MST, 74°F. The sky was clear. This night was the 5th anniversary of "First Light" with my 8" LX200-ACF telescope. At 1825 MST, viewed Mercury and Saturn, low in the sky and into some trees, 83X. Then viewed Venus, 83X.
Next, slewed the 8" to the waxing gibbous moon and viewed it at 83X. I took this photo with the iPhone 5s, afocal 83X, handheld:
I then switched to the 2" 9mm 100° eyepiece (222X) and did some lunar terminator touring. I decided to image Mare Humorum again this night to show the difference in the view from the previous night. While waiting for the moon to rise a little higher in the sky, I did some moonlit terrestrial viewing using a nightscope.
At 1859 MST, I began doing afocal (222X) video recording using the iPhone 5s of Mare Humorum. This was the image I captured the previous night:
And this is the image from this night at almost the same scale:
The large crater on the north rim of Mare Humorum is Gassendi.
I resumed lunar observing at 1911 MST. Seeing was still not very good again this night. I did a little more terrestrial nightscope viewing for a few minutes. At 1920 MST, I took a last look at the moon, 222X and 83X.
The observatory was closed at 1930 MST, 62°F.
