After I arrived at the observatory I could see the planets Mercury and Saturn low in the southwestern sky. I found a good location where I could see the planets as well as Kitt Peak National Observatory (65 miles away). It was a pretty sight.

This is a slightly cropped handheld iPhone 8 Plus photo taken with the 2X telephoto lens using the Camera app. The Mayall 4-meter telescope dome is visible in the photo at the right edge of the flat mountain top of Kitt Peak.

1818 MST: LX600 ON, StarLock OFF, High Precision OFF.

Viewed the Moon, 102X and 81X. The star Theta Capricorni was visible just to the south of the Moon.

Mounted the iPhone on the 30mm eyepiece using the Levenhuk adapter for this photo of the Moon and Theta Capricorni taken with the iOS app NightCap Camera (ISO 22, 1/45sec):


Switched to a 2" 9mm 100° eyepiece to do some lunar observing, 271X. The craters Aristoteles and Eudoxus in the north and the craters Theophilus, Cyrillus, and Catharina in the south looked especially nice this night. I decided to image them, afocal 271X.

Craters Aristoteles and Eudoxus (ISO 22, 1/150sec)

Craters Theophilus, Cyrillus, and Catharina (ISO 22, 1/70sec)

I switched to use the iPhone 8 Plus 2X telephoto lens for a little more magnification for these photos.
