I'm back from my business trip to the USA. I tested my new Astronomik LRGB Type 2c filter. Interestingly, it isn't as good as my old Edmund Scientific LRGB filter. I would like other feed backs on the Astronomik filter. The red filter seems to have a lower transmission than the Edmund Scientific filter.
Here's an image of Jupiter's busy NTrZ/NTB region. The bright white spots and the huge dark feature are very prominent in this region. It seems like the bright spot has a "tail" which is interacting with the NEBn. The Northern Hemisphere seems to be joining the southern hemisphere upheaval!
The SEBn is almost all yellow now.
