@ . . . . . . . . . . Greeting everyone...
It has been great to see all of the great images of Jupiter and Saturn this fall. I am sending my first contributions of Jupiter taken the morning of Oct 31.
Seeing was good, but I was clouded out part way through the session. All images taken trough my 30cm SCt at f20 using the Pixcel 237 in high res mode. Details on images, let me know if anyone has any questions.
P.S. I am using the same mailing group as last year. If there is anyone who wishes to be removed, or can suggest anyone to add, please let me know.

@ . . . . . . . . . .Hello Everyone...
I have attached a set of images captured on Nov 16.
They include IR and Methane band images. There is a great deal of activity along the north edge of the NEB, with several large dark marking present, the preceding pair appear to have a loop of material between them which is contrasted against the EZ. There is also a dark spot in the STeZ or on the edge of the STeB which can be seen approaching the CM as the image sequences proceed. There appears to be a lighter zone immediately preceding this spot which is especially visible in the methane images. Io is emerging from behind the Disk of Jupiter in a few images, cropped out of most though.
All images taken through my 30cm SCT at F40 (eyepiece projection) and Pixcel 237 CCD camera. I was trying a new setup and got the f ratio too high. This resulted in longer exposures than ideally required. Seeing was good, 6/10 on average. Air temp was –12ﾟC.
Please let me know if you have any questions.
