Jupiter and Europa
      #6224473 - 11/30/13 12:50 AM Attachment (29 downloads)

On Friday evening after setting up to observe, I could see sky conditions would be better than average for this time of year( late fall).
When Jupiter climbed to more than 60 degrees above the horizon, I realized that this would be the night to make a first sketch of Jupiter for the season.
The GRS was redder than last season especially in its center and was well set apart from both the South Tropical Zone and South Equatorial Belt. Europa had just emerged from behind the North Tropical Zone on the following side of the planet. A couple of festoons could be clearly seen in the Equatorial Zone emerging from the North Equatorial Belt.
It was right at my tolerable cold temperature limit for sketching and I finished before needing to retreat indoors to warm up.
On a steady night of good seeing this is the time to give Jupiter a look.

Equipment Used: 13.1 inch f/6 Dobsonian running on an equatorial platform 6mm eyepiece (333x) and Baader Neodymium filter

Sketching: Assorted graphite pencils, medium hard charcoal pencils, erasers, blending stumps,
white copy paper
Seeing: Pickering 7/10
Transparency : Average 3/5
Temperature: 21F (-6C)
Jupiter: Visual mag. -2.6, Diameter 44.65 , illumination 99.6%, distance from earth 4.4 au

P.S. If you want to read an excellent article on sketching Jupiter see the January 2014 Sky & Telescope article written by CN's very own Special Ed - Michael Rosolina.

Frank, very nice - very nice! I like the way you've applied the contrasts - gives the fluttering detail look . I had my first view tonight with it about a foot over my roof . I think it was a combined Pickering 2 between the sky and the local heat sources . Nothing like your fine view!

Baader Neodymium filter



How is the filter helping in observing Jupiter?

Frank, great detail. Lots of detail. I like the way you sketched the GRS wake, spot on. I'd recognize it anywhere.

You're showing some albedo in the NEB. I'm finding that extremely difficult to pin down. There are only hints of being some discernible features, but they also appear to be just out of range in my small aperture.

Nice to see you freezing your tootsies off to observe Jupiter. I hope you get out often. (Kidding, of course, about the freezing part.)

Is Michael's article out, yet? I'd love to read it, thanks for the heads up.

Pete, Christian, Jef, Norme,

Thank you all.
---
Pete- I have looked at Jupiter several times recently but the seeing was as you described not too good. I didn't expect too much this time but after cooling the scope for 3 hours it settled down.

---
Christian - the Jan.2014 S&T is kind of a Jupiter issue.

---
Jef - Using the 13 inch and 18 inch scopes I get better contrast and better color on Jupiter, Saturn and Mars.
The difference is not great but improved.

---
Norme- Subscribers issues are likely in the mail now.
I can just tolerate these temperatures if it is not windy.
When the wind picks up in the cold my eyes water.

Frank

Great job. You got a great deal of detail. Good job braving the cold.

I just read Michael's article. Bravo!

Great sketch of the king, very detailed, great job with the grs looks perfect, many sketchers draw the grs too big but you certainly have a fine eye, glad you got a chance to get out in cloudy December.

Yes beautiful sketch indeed. I know just what you mean about watering eyes. Throughout so much of the winter my two scopes just collect dust...

Frank, this drawing is simply beautiful. I love your sketching style, and your presentation. The rotation of the disk offers a realistic sense of how it appeared at the eyepiece. Thanks for the heads up on Michael's article. I'll have to hunt down an issue just to see that!

Frank,
Terrific sketch with loads of detail and well rendered contrast variations. Jupiter's appearance is a very realistic eyepiece view.

Good for you braving the weather--21 deg F is cold to work in.

Thanks for the plug about my article. Folks here in the Sketching forum were in my thoughts as I wrote it. BTW, it is in the January issue which comes out the first week of December.

@Ken--Thanks!

Thanks for correcting my error. I went back and fixed my mistake on the S&T issue.

Nice work Frank. The GRS has more color this time around, and you picked-up the darker section within-it.

Rutilus,

Yes the GRS really surprised me as to its color. Much redder than I remember it to be in decades.

Thank you for the kind words.

Frank
