I have not sketched Saturn this go around until now because of extremely poor weather so far this year. On Wednesday evening the atmosphere cooperated and I had a scope outside cooling down. I did not have access to any Saturn templates because of a computer crash. So I took out my old mechanical drawing equipment and made an ellipse of the approximate eccentricity of Saturn’s rings and sketched from there. It’s a bit crude but reasonably close to the view. Seeing was good and the atmosphere was transparent. I was able to see Mimas but it was just beyond the way I framed the sketch for posting. Enceladus was about 12th magnitude.
Date: 06/20/2013, 01:45 – 02:45 UT
Sky Conditions: Partly cloudy
Seeing: Pickering 7/10
For sketching I used 10” x 12” Canson black paper, white, gray, charcoal and black pastel pencils, powdered Conte’ crayons, white Pearl eraser, blending stumps.
Equipment: 18” f/4.95 Dobsonian with a 9mm ortho eyepiece for 250 x.
Neodymium filter and single polarizing filter
I present to you my latest sketch of the Jupiter.
Sketch was made by pastels on the navy blue paper and it is also some corrected with GIMP (especially the roundness of the planet).
Jupiter was observed through my SCT 5″ on December 1st, 2012.

Height above the horizon 36 º Observation at sea level in Barcelona (Spain)
Media: pencil in white paper, Microsoft Paint
Horizontal image investment because used diagonal mirror.
The predominant color on the planet is a very pale yellow (at other times showed an intense golden) contrasting with some greyish belts with ill-defined irregularities. It clearly shows the shadow of the planet on the rings.
The Cassini Division shows a high contrast and a black is intense and well defined.
I could clearly see the satellites Titan, Rhea, Dione. Tethys only very weakly.
Enceladus, I’d be on the limit of this equip, but It was not possible to distinguish. Mimas is beyond the scope of this opening.
yesterday the weather was the first time very good. And the night was great. After many deep-sky-impressions I waited for Saturn and the air was as good as possible.
It is my first Saturn sketch in 2013 and I sketched the ring-planet without any helps. So I need about 20 minutes for the ring system only. It is very hard to sketch it quite well and it needs little work in the warm living room after the session. 😉

Last night a nice transit of Jupiter’s moon Io was visible from Europe. The transit of Io (and its shadow) started when Jupiter was still very low in the East, but it rose very quickly. Seeing conditions improved and more details became visible. It was a very foggy evening in the Netherlands, but Jupiter just peeked through the mist. The tiny black dot of Io’s shadow was immediately visible. The moon itself became visible when it moved more to the limb of the planet (due to the edge darkening of Jupiter).
I made a small (2″ diameter), quick sketch of the view through my 16″ Dobson at 225x. I later enhanced the contrast and colorised it a bit with Photoshop, to match the actual view through the eyepiece as much as possible.
(It is one of my first sketches of Jupiter, so I sketched it a bit too small. Next time I’ll try to sketch a bigger planet, maybe 4″.)
I would like to show you my latest sketch made with binoculars 10×50. On the right side are Hyades, and in the left-top part shines the Jupiter.
I used the graphite pencil on white paper. Then sketch was inverted. There are some little corrections in GIMP.
Last night (November 18) Io was transiting Jupiter. I made a sketch of the event from 19:30 – 20:00 UT. The telescope used was an Astrosib 250 mm f/8 Ritchey-Chretien, with magnifications between 91x and 370x (Vixen LVW 13 & 22 mm + Barlow). The sketch has been made behind the telescope and drawn with a 3B graphite pencil. However, I played with it in Photoshop (CS4) to mimic the seeing.
