Jupiter UTC
CM1: 164.00°
CM2: 233.40°
CM3: 397.30°
CLat: -1.40°
Description
Excellent conditions to start with until more turbulent air moved in. I removed the extension tube from my BARADV and attached it to my cameras's nosepiece for a more optimal image scale.
A segment of the SSTB appears to be reddish in color.
