After a couple of days of wicked rain and wind the sky cleared out and I was blessed with excellent seeing and good transparency.

This sketched observation was done with the usual 4H and HB pencils.

I find the appearance of SEB from recent observations to be very interesting and challenging from an observer's/sketcher's point of view

Best,

Sol,

What a magnificent sketch! I am in awe of your planetrary observing skills, as well as your artistic renderings.Unfortuntaely, my artistic education ended in primary school, though I continue to learn from your book.

Best wishes,

Neil :cool:

Neil & Dweller,

Thanks for the compliments. One thing I forgot to mention was that the SEB and EZ were rendered in IL. The Wratten 56 was a bit too much for them.

Neil, Great refractor article!

Thanks again,

Sol, great work as always. Does the Chromacor invert the image?

Sol,

Superb sketch. Both equatorial belts show a great amount of detail. That light green filter is a good one for Jupiter.
Excellent post.

Frank :)

Thank you all for the encouraging words.

The Chromacor II does not invert anything. It does shorten the effective focal length from 1200mm to 1120mm.

Sol,

An outstanding observation of Jupiter. You have captured an impressive amount of detail across the jovian disk. The regions between the South South South Temperate Belt (SSSTB) and the South Temperate Belt (STB) appears interesting and complex. The North Equatorial Belt (NEB) is full of interesting features (bright rifts, dark condensations, and white ovals). The South Equatorial Belt (SEB) is difficult to reproduce from an observer's (sketcher's) perspective. An observer is able to make out the hint of detail "beneath a veil" when the seeing steadies. I am excited about it's revival which can happen any moment. Thank you for sharing it with us all.

Carlos

Sol,
Outstanding work. The NEB looks very busy.

Thanks. The SEb seems to be morphing back into its former self. It ought to be interesting to seB this develop.

Thanks again,
