Description

I decided to setup the C8 even though I wasn't convinced in the moment the sky conditions would be good. The live view was turbulent, but slower than I'm used to seeing. I had both my imaging trains in the same place, so I decided to do a comparison between my ZWO filters for the C8 and my Chroma filters used with the C11 and C14. This image was done through the ZWO filters, while next image will be with the Chroma filters.

Notes:

  • White Oval Z is faintly visible on the North Equatorial Belt, north of the Great Red Spot.
  • The Equatorial Zone is orange.
  • The GRS is off-center in its hollow.
  • The GRS hollow is unusually dark.
  • South Equatorial Belt clouds are circulating around the GRS and into the South Tropical Zone to the east.
  • The SEBs is dark and clumpy.
  • Io and Europa appear left and right of the planet respectively.
