This was a planned short session.

1853 MST: LX600 ON, StarLock OFF, High Precision OFF.

Viewed the Moon, 102X and 81X.

Took this handheld iPhone 8 Plus photo of the Moon, afocal 81X, using the iOS app NightCap Camera (ISO 22, 1/3200sec):


Switched to a 8-24mm zoom eyepiece and did some lunar observing.

Took this handheld iPhone photo of crater Clavius (center) with the crater Tycho (above center), afocal 305X, using the iOS app NightCap Camera (ISO 22, 1/80sec):


1913 MST: slewed the telescope to the star Rigel and SYNCed the AutoStar. Checked the component star separation, which is similar to the separation of Sirius A and Sirius B using 305X. Then slewed to Sirius and began trying to see the "Pup Star" (Sirius B). Unfortunately, I was unable to see the Pup Star due to the glare from Sirius A. Will try again when the sky is brighter.

1925 MST: LX600 OFF.
