Cloudy session,
iPhone Albireo Double Star

Posted: 8 August 2021

Thursday, 5 August 2021, dawned clear, but the Monsoon pattern began re-establishing itself with cumulus cloud buildups mid-afternoon and clouds continued into the night. Friday, 6 August, was cloudy.

Saturday, 7 August, dawned clear, but some clouds began appearing mid-afternoon. Fortunately, it was mostly clear in the late afternoon. Although I didn't have high confidence that the sky would be clear enough to photograph what I had planned for the session, I decided to open the observatory anyway.

After opening the observatory I relaxed on the observatory patio bench to monitor the clouds.

1920 MST: sunset.


The clouds began increasing. I decided to do some observing before the cloud cover became worse.

1944 MST: LX600 ON, StarLock OFF, High Precision OFF.

Viewed Venus, 102X, through the clouds to the west. A nice gibbous phase was visible.

The viewed the double star Albireo, 102X, through thin clouds.

This is a handheld iPhone 11 Pro Max photo of Albireo, afocal 102X, taken using the iOS app NightCap Camera (Light Boost, ISO 3200, 1/4sec, 1X lens).


By now the clouds were in most of the sky. Decided to give up for the night.

1959 MST: LX600 OFF.
