Special Visitor, Harvest Moon
Posted: 21 September 2021
Friday, 17 September 2021, was cloudy. We took my visiting niece to Kartchner Caverns State Park and then Tombstone, Arizona (my photo gallery). Saturday, 18 September, my niece and I attended GLOW in Oracle at night. The sky was cloudy anyway with a brief rainshower (0.03"). Sunday, 19 September, was mostly cloudy. Monday, 20 September, was mostly clear during the day with considerably less haze than we had had for several days. After a day trip visiting Sabino Canyon and driving up Mt Lemmon with my niece Linda, I opened the observatory.

Conditions: Partly clear
12" f/8 LX600 w/StarLock

2" 30mm eyepiece

We viewed the just-past Full "Harvest" Moon, 102X and 81X. I added a "moon filter" to reduce the brightness of the Moon.
I took this handheld iPhone 11 Pro Max afocal 81X photo of the Moon using the iOS app NightCap Camera (ISO 32, 1/5200sec, 1X lens).
We then viewed Saturn and its moon Titan, 102X.
Next, we viewed Jupiter and the four Galilean Moons, 271X and 102X. There were two of the moons very close together, with all four moons to one side of the planet's disk.
