Pastel sketch: Sinus Iridium
      #4517713 - 04/14/11 12:40 PM

Yesterday I made a pastel sketch of one of the nicest features on the Moon: Sinus Iridium. The Sun's angle was just right to give the surface that gradient view: dark near Montes Jura with a gradual brightening towards the west. A few rilles were also visible. It was a very pretty sight through my 300mm f/4 truss Dob using a 5mm HR Planetary eyepiece (240x). Sketch made with white pastel on black paper.

Beautiful drawing of Sinus Iridium Roel! Your style is wonderfully realistic and at first glance the small version with your post looked like a photo.

And one more well deserved compliment for that one !!! Verrry beautiful.
Looking closer, I notice exactly what I saw yesterday: the nice triangular shape of Promontorium Laplace: very impressive. Keep on feeding us.

Roel,

An amazing capture in white pastel on black paper. I have seen this view many times over the decades and your sketch is a spectacular capture of that view.
Wonderful post.

Frank

Great work, Roel. If reincarnation excist, I want the same artist skills!

Stunning.....It's amazing!

What size is the original?
I'd like to see it at full screen resolution if possible, to be able to see the way the pastel was laid down, the brush strokes etc.

Thanks a lot for the kind words!

The original size is around 8" x 10". I sketched it on a A4 size black paper. This is the largest version I have at the moment:

To make a full screen image I have to take another picture of the sketch in daylight. I'll place a link here tomorrow.

Roel, now I'm even more amazed. It's only 8" x 10" ?!!

I thought it must have been at least twice that size, the detail is incredibly fine. For example the texture of the floors of the two craters in the upper left, the speckling must be minute!!
There are also some jagged lines in the wall of the basin on the right had side near the terminator, they must have been added with a 0.5mm mechanical pencil.

I'm blown away!

Thanks!!

Actually, that just the texture of the paper itself, I didn't really apply those speckles. The crater floor is in fact the partly erased white backgroud. Because the white pastel background is firmly rubbed into the surface of the paper, the eraser only picks up the upper part, leaving some pastel in the "grooves".

Those are scratches in the white pastel, made with a very sharp tipped graphite pencil. I always end my sketch with adding some of those fine details.

Roel,

An outstanding and very realistic observation of Sinus Iridum. You have captured this section of the Moon very nicely. Thank you for sharing it with us all.

Carlos
