Although Jupiter has been visible in the morning sky for a while now, the wait for clear weather has finally ended. As the sky brightened, it was breezy and the air above was very turbulent. This was my first time having insulation wrapped around the OTA while imaging a planet. Despite having just bringing the scope out to a cooler environment, I saw no internal heat plume while collimating the secondary mirror.
This was also the first time I used my Chroma extended green filter on Jupiter. As expected, the new filter gave a brighter image compared to the standard green. The 11:59 image uses the standard green filter while the 12:00 image uses the extended green. I am hoping for better conditions soon so I can create a solid comparison between both filters.
The Equatorial Zone is still orange like it has been for the past 3 apparitions. The North Equatorial Belt is noticeably darker than the South Equatorial Belt.
