Hello sketching friends !

 

I had the opportunity to observe the small planet just at the good time.

 

I mean :

  • the day of opposition
  • the time to observe close to the meridian 
  • the weather with a stable atmosphere

I also used a good "slow telescope" I think the best one for this type of observation:  a f15 Mewlon and some good eyepieces are the keys for this observation.

You can read a very good summary of what we now about this small planet, writen by Bob King for Sky and Telescope here:

https://skyandtelesc...to-visit-vesta/

 

Don't hesitated to have a look, a sketch is included wink.gif  !

 

As eyepieces I used only TeleVue's: a 10mm Delos, a 13 mm Ethos and a 3-6mm Nagler zoom as well as a 2.5mm (6) Nagler

The best view was the one with the zoom on 3mm

The 10mm Delos (375x) show me already that the shape of this object was not a star, but that was the limit.

The view with the Nagler zoom fixed at 3mm was the best view, maybe because when using the 2.5mm the sky was not so stable.

 

The observation gives me two information, the first one is that the shape of Vesta was not a pin point like a star, I was wondering if I was not able to see that the disk was not perfectly cirular, but I know it's probably impossible.

The second info is related to the color of the little planet, I see that as clear Napoli yellow, in french Jaune de Naples,

here the value from my Winsor & Newton watercolor pallet that I use:

It's funny to observe such a small object, so far and lost in our huge stellar system.

 

Clear sky and virusfree to you all

Michel

Michel,

 

Beautifully done. I have not looked at Vesta for 2 years now. This is a good time to have another look.

Very nice sketching.

 

Frank :)

Hi Michel,

 

Very many thanks for bringing this little gem to my attention. And congratulations on having your sketch included in Sky & Telescope. I couldn't help but smile when I saw that the S&T sketch was done on my birthday. smile.gif

 

Clear skies,

Darren.

Michel,

 

I was out a short while ago and looked at Vesta; you captured the color very well. Frank :)

Thank you Tom and Gamma

Clear skies,

Darren.

Thank you a lot Darren, this is because the redacrtors of Sky and Telescope have an eye on our sketches here in CloudyNights, this must be motivating for all of us !

 

Michel,

Thank you a lot Frank, you have always so positive words !

I'm a great fan of colors, as David Gray with it's uncredible planets and stars comparisons.  It's because of such sketchers (as David) that I buy my Dall Kirkham Takahashi scope.  This is another effect of CloudyNights, ok, more expensive than looking at our sketch in S&T smile.gif  !

 

Here attached my (very heavy) natural box with mineral (mainly) pure pigments from the area of Florence Italy. 

The one used for Vesta is the one in middle box, first row up.

Such pigments are used to invent new colors.

I really like this. I have been checking out this and the other big 4 asteroids for observing opportunities today.
Now I need a clear sky

I've plotted the paths of asteroids through the constellations before but not tried to resolve a disc yet, this has given me something new to try for.
Thanks Michel!

Thank you for the sketch. I have been following Vesta for several days now and was really taken by the color. But, no one mentions its color. I was delighted to see your sketch and the “conspicuous” color.

Edit: just read the S&T piece. Congratulations! Great sketch and perfect word choice.

Michel,

 

Very nice set of sketches of 4 Vesta.  waytogo.gif   Great observations and congratulations on those conditions--1500x!   shocked.gif 

 

I've always seen Vesta as a yellow/gold color with a certain quality different from starlight.  Hard to describe but it looks different than a star.

 

Congratulations on your sketch included in the S&T article.  Bob King has been very good about using sketches in his articles.  He even used one of my Mars sketches one time.  blush.gif

Thank you to you all.  Really !

Indeed this "amber" color is the information which is the most visible.

Indeed Bob King use CloudyNights to share sketches as well, this is so good!.

I did a watercolor-souvenir of this opposition

aquarelle4vestaB-s-zoom_l.jpg

 

and... and... I just buy a very very small piece of Vesta !!!

 

Diogenite-NWA7831_l.jpg

 

This is a 22gr DIOGENITE (HED) NWA 7831 founded in 2013 Western Sahara

https://en.wikipedia.../wiki/Diogenite

 

What is strange is the similarity between the color of my sketch and that of the meteorite.

Michel,

 

Very fine souvenirs both the Vesta art and the meteorite from the Sahara. Excellent.

You now have two great views of the space rock.

I took a look at Vesta a few nights ago, remarkable color indeed but was unable to resolve the disk. I did not try too hard though.
