1756 MST: LX600 ON, StarLock OFF, High Precision OFF.

Viewed Saturn, 102X.

Then viewed the Moon, 102X and 81X.

Mounted the iPhone 8 Plus on the 30mm eyepiece using the Levenhuk adapter. This afocal 81X photo was taken with the iOS app NightCap Camera (ISO 25, 1/1000sec):


Switched to the Explore Scientific 9mm eyepiece and did some lunar observing. Clavius looked nice with sunrise occurring at the crater.

Mounted the iPhone on the 9mm eyepiece for this afocal 271X NightCap Camera image (ISO 25, 1/60sec):


Added the Televue 2X PowerMate. Seeing was not great but decided to try an image anyway. This afocal 542X NightCap Camera image (ISO 125, 1/30sec) is the result:


1826 MST: began watching sunrise at Clavius, 542X. It was fun watching more of the main crater floor become visible. 1902 MST: ended lunar observing.

Slewed the 12" telescope to the star Epsilon Lyrae (Double-Double Star). Viewed it using 542X. Seeing was not great, but I could separate the components at times.

Mounted the iPhone 8 Plus and did some imaging. This afocal 542X NightCap Camera (ISO 250, 1/35sec) image was the best, showing the four stars:


1914 MST: returned to the Moon and viewed Clavius crater, 542X. Then did some sightseeing along the lunar terminator, 271X.

1922 MST: last look the Moon, 102X.
