Jupiter – 1 April 2015


This sketch of my favorite planet of the solar system, that day their moons aligned, the great red spot and below this, the shadow of Europe, the picture was very rewarding and enjoyed meeting observation, but since the city only allows this type comments, try to have a place for these events really impressive. The original sketch was reduced and adjusted as is the eyepiece.

Best regards.

Hi This is a sketch of the planet Jupiter made throught my 6” achromatic refractor (TS Individual 152/900), binoviewer, a pair of 8 mm eyepieces and glasspath that gave me 293x. The seeing was very good during all the observation, allthought the arriving of high clouds at 01:00 am ended with the fun.

It was remarcable the wedge that seems to divide the NEB and a bright patch between this belt and NTB that reminds a great oval.

I hope you to enjoy with this sketch.

Conditions: Seeing: 3.
Observations: The size does not represent de actual FOV. I used different powers because some details were visible with certain EP’s. The drawing took me around 45 minutes, so the planet rotation was noticeable!

Tango Between Two Jupitermoons

Europa and Ganymede
Europa and Ganymede


I made a digital animation in GIMP of a partial eclipse of Europa by Ganymede (27%). During the event I saw clearly a “division” between the two moons but it was impossible to tell which moon was before the other. Because I couldn’t detect any color difference between the two moons I guess the “division” was an optical illusion due to the 8-figure. Hope you like it!

Jupiter – Io covered Europa

Jupiter and Moons – 26 February 2015

Last week at the 26th. February I took the chance to make a sketch of the mutual moon cover. Of course, I also observed Jupiter. The air was not so good but in quite moments there were some details to hold.
All in all it was a real fantastic night. First ran Callisto and its shadow over the planet. Then Kallisto covered Europa and at last moved Io over the planetary disk followed by his shadow.

I enjoyed the Moment when Io covered Europe and sketched this nice scenery for my astro-log.

Jupiter and Moons – 12 February 2015

Hi Asod! This is my first astronomic sketch of a planet. I decided to represent Juppiter because I love its moons and their positions, expecially last night, when I realized this sketch. From left to right: Callisto, Io, Ganimede, JUPITER, Europa. I observed it with my dobsonian telescope 10″ f/5 using a 14mm 82° eyepiece. I realized the sketch with pencils on white paper, then inverted.

Jupiter triple shadow transit – 24 January 2015

Object Name: Jupiter
Object Type: Planet
Location: Stokesley, North Yorkshire, UK
Date: 24th January 2015
Media: HB, B, 4B pencils, blending stumps, kneadable eraser on white paper

I used a 130mm reflector at 100x to make this sketch. The weather was cold and clear with good seeing and a limiting magnitude of 5.4. Despite the good seeing, I had to be quite patient to see all the shadows. Callisto itself was easy but Io was quite difficult. It was wonderful to see the shadows suddenly appear during moments of good seeing but at other times not all of them were visible at any one time.

Triple Transit Face on Jupiter

Jupiter Triple Transit - 23 January 2015
Jupiter Triple Transit – 23 January 2015

On Friday, January 23rd, there was a triple moon transit on Jupiter. Io, Europa, and Callisto all crossed the planet’s disk and cast shadows on their way. It was a busy night for several hours, but at 11:10 Pacific time the view became almost comical: Io and Europa made tiny ears on either side of the planet while Callisto and its shadow provided eyes and Europa’s shadow provided a mole above the left eye. The polar regions provided a stocking cap and a bushy beard.

The view was through a 12.5″ binocular telescope, which added a 3-dimensional effect that really made the face stand out. The extra mirrors in the binocular scope create an image that’s upside down but correct left-right.

Object Name (Uranus with moons)
Object Type (Planet and satellites)
Location : Observatoire Astronomique de Bauduen, Provence France
Date 2014 Dec 11th
Media (graphite pencil, and inverted watercolor on white paper, Paint.net for the inversion)
That’s maybe because I like to use this great telescope, or it’s because I like challenges but,… it’s certainly not the best optical combination for this observation.
On 11 December, I finally found a corner of pure sky above the 24-inch reflector made by Olivier Planchon. To observe Uranus, the speed is definitely too high: f / 3.3 d, so we had to use very short focal EP to reach the useful magnification (Nagler 3.7 and 2.5) !.
If you look at my watercolor you can see a somewhat elongated comet hair that diffuse around the planet, that’s exactly how we see the planet area in the field, this is probably linked to a not 100% perfect collimation, but still. I get the impression that the work of collimation facing these big tubes, it is not a piece of cake.
Anyway, we can say two things:
1- We observed three of the Uranus satellites: Oberon, Titania and Ariel, this last one being a bit lost in the lights of the planet
2- the disk of the planet was not uniform as seen in a small telescope or some photos. It’s very difficult to confirm, but a diffuse zone clearer was observed in the upper atmosphere of Uranus, is that an artifact, I do not know? Anyway the main direction of the area is not in the direction of the cloud bands of Uranus.
