Monsoon Lightning, Venus, Cloud Shortened Session
Posted: 4 July 2015
There was a brief monsoon storm at Cassiopeia Observatory early Friday morning, 3 July 2015. One of my webcams captured some lightning to the north:
The storm only dropped 0.06" of rain here. The sky became partly cloudy in the late afternoon and as sunset approached I decided to open the observatory.
Open: Friday, 3 July 2015, 1900 MST
Conditions: Partly cloudy
1907 MST: after powering on the 8" LX200-ACF I viewed Venus then Jupiter at 83X. Their separation was now too wide to fit in the same field-of-view.
Slewed back to Venus to image it before the clouds reached it. Mounted the D7200 DSLR for eyepiece projection 222X. This is a stack of 939 frames from a 15 second HD video recording, 1.3X crop factor, 60 frames/second, 1/60sec, ISO 400:
1918 MST: clouds were now in most of the sky. Ended Venus imaging.
1931 MST: viewed Saturn, 83X, through thin clouds.
Sunset was obscured by clouds, but the sky was rather pretty, as seen in these photos:
View from observatory to southeast
View from observatory to east
View from observatory to west
1943 MST: powered off the telescope due to the clouds.
1950 MST: Jupiter was now faintly visible to the naked eye through the clouds.
Close: Friday, 3 July 2015, 2000 MST
Session Length: 1h 00m|
Conditions: Mostly cloudy
