Here is my Jupiter sketch on the morning of September 27th. GRS looks orange-pale, not like in the last years when was more pronounced. NEB presented some festoons and SEB looked dark-gray, not the usual dark-red.

Again a nice Jupiter with a lot of detail.
BTW, I finaly got a Neodymium-filter but didn't have yet clear skies to test him. Does it change the color of the planets?

Thanks!
The Baader M&S filter do not shift the color in general, the tones of the planets with filter on are slighty cooler(or cooler white), but with higher contrast. The reason that my sketch seems different now is that I'm using an achromat and at eyepice this is how it looks, I'm tring to render what I'm seeing with or without the filter, even the CA effect on planet's tones. Past sketches were done with an Dobson telescope and present more warmer(and with the filter on more neutral)tones.
