Jupiter and Mars november 12 2022

#1

Post by John Baars »


Last Saturday night, the GRS on Jupiter passed by at an auspicious time. Seeing was not that great, but still got the planetary scope out. Three naked-eye planets, what more could you want?
I equipped the 120mm Evostar with an Atmospheric Dispersion Corrector, a notorious seeing suppressor, and got to work. Also, a barlow and my Leica zoom eyepiece. The combination of the two ( and another intermediate) put magnifications of 50 to 250X at my disposal. That had to be enough. Just in for the news and let the gear cool down.
The GRS was initially halfway up. Very favorable, in other words. When I focused there was just a moment of calm seeing, so I was hopeful. It soon became apparent that I had to adjust my expectations a bit. So I had to go down to a lower magnification.
The GRS was clearly orange-pink, with a lot of turbulent storms around it. One of them was clearly whiter and more striking than the rest. Diagonally below the GRS, another darker spot was visible. All in all, a beautiful sight. I briefly listed the details for myself so I could make a first sketch inside later.

After a while I saw Mars peeking out over the houses and treetops in the East. In company with the Moon. Whew..... this was not going to be anything so low on the horizon. Then let's look for some open star clusters. Losing time... The Pleiades invited themselves. In the group, with the Moon as a clear hindrance, I counted about sixty stars. Remarkable that the Moon has so much influence. A week earlier I counted over 80, with a smaller refractor but the same magnification and eyepiece. It appeared that I could get to magnitude 12 with some difficulty. Without the Moon I get deeper. NGC884, NGC869, the double open cluster in Perseus were the next candidates, sidelined by Stock 2. One more pass by the ET cluster NGC457 and stop at Mirach for NGC 404, Mirach's Ghost. Although I was sure it was out of range due to the Moon .
Mars had detached itself from the row of trees and houses beyond, Mars time! The blue/white clouds, which have been written about for the last week, on the northern edge stood out right away. This was so bright, this couldn't just be Hellas . Several sources had assured me that it was NOT a polar cap either. Very noticeable is the bright edge on the left of the sketch. It seemed to encompass just about half the planet!

Saturated, I looked up and saw a familiar Winter constellation peeking above the horizon there. I thought that was a nice finish .

A nice report and sketches John.
I have managed some good views of Saturn and Jupiter so far but not had a long view of Mars yet.

Wonderful report on Jupiter and Mars with beautiful sketches John! I need to revisit Jupiter and look more carefully for the surface details (incl. GRS) that you and Andrey sketched/described. Same for Saturn as well (shadows).

Haven't looked at Mars yet - now I won't mistake a cloud for the polar cap or Hellas!
