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.

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 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.

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.

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.

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.

The (Planet) Jupiter is one of the most difficult objects to observe. lt has most delicate subtle figures on surface atmosphere. Speak frankly my 13″ og showed me nothing but two main belts and 3-4 minor belts since first light the fall 2013 that not ones to surpass 12″, 8″, 6″, or 5″ED or 8″ dob at least in detail performance. Tonight’ early morning It showed me countless wrinkles on the King’s face though just at the 5-6 number of times one time was only shortest moments 2-3 seconds for 10 minutes with rated 9/10 seeing. The other interesting features were as you see [1], on the nights last autumn just near the first light night, the Europa’s color was turkish blue gray, but on this night it was pale yellow, the surface color of Europa really changed after one year ? The optical train was(is) same; flat-og-tv bino- tv nagler 7sThe [2]….. 13″ OG showed Ganymede’s contact moment with Jupiter’s limb, because the 13″ achromat’s chromatic dispersion effect of light produced weak contrast, could not identifyed the exact situation of the contact moment. For 10 minutes Ganymede moved 5280kmx0.7=3696km, the projected velocity of Ganymede is calculated as 3696km/ 600s= 6.16km/every second. # l usually write the observing date till fully to dawn as the same day .

What Happened to the Great Red Spot?

Planet Jupiter and the Great Red Spot (GRS) - November 11, 1975
Planet Jupiter and the Great Red Spot (GRS) – November 11, 1975


Why did the GRS get lighter and smaller after 1975?
As you see under my sketch, the GRS was brickred before a white spot became in
and passed the GRS on 9. nov. -75.
The GRS had allways a brick-red color before this happened, and since then, it
has been light red, orange or yellow!
The GRS was very easy to see on the disc of the planet before that!
Can anyone tell what happened?

I used color – pencils on black paper.

I woke up early at 5:00 o’clock to take a look at this marvelous conjunction. It was still night at the time and I was surprised with a mighty view of the rising Orion. I waited on my balcony for until the planets were visible over the roofs in front me. I quickly took my pencil and drew what I saw on the eyepiece of telescope, but the seeing was awful and just two moons were visible. The view of this two small lights dancing together over the roof in the cold morning was much more intriguing, so I tried to sketch the whole landscape. Never tried this kind of astronomy sketch before, probably my first landscape since I was a child.

– Dobson Orion XT12 (305 x 1500mm => F/D 5)
– Eyepiece Panoptic 15mm + barlow x 3 Televue (mag x 300)

After a heavy rain, the sky suddenly went cristal clear. So I took my Dobson to a dark lane.

After having a long M82 supernova contemplation, I payed attention to Jupiter.
Its moons were in a rare configuration: all on the same side, but forming a trapeze instead of a line.
From left to right: Io, Callisto, Ganymede, Europa.

I was surprised by the amazing sky quality, seeing perfectly the Great Red Spot and some detail on tropical strips.
I saw an unusual white wave on the right side of the GRS I wanted to keep in memory by doing this sketch.

I could not establish if it was a continuous stream (as I draw it) or a suite of white storm clouds.
I did not find recent picture of Jupiter to confirm.
If somebody observed this, or made a picture at the same period, thanks for leaving a comment.

Thanks for your interest.

Jupiter – October 27, 2013

Hi everyone!

I didn’t like observation of solar system members.

Since it’s strong brightness, I can’t make dark adaption in my eyes.

One day, under the moonlight.. I didn’t find deepsky anymore..

So I started observing & sketching the Jupiter.

Because it’s altitude is proper to observing with my 15″ Dob!

The more I saw the Jupiter, the more structure appeared my eyes.

It is a kind of miracle!

Unfortunately, I don’t have experience of Jupiter sketching.

It is not good planet sketch.. but it is my first true experience of observing Jupiter!

Jupiter-Season starts…
for me at 25.11.2013.
The conditions were fantastic. I watched with my TMB 115/805 and saw many beautiful details on the big gas-planet.
I enjoyed the time at the eyepiece and tried to record all the clouds swirl. But it was not easy to put everything on the paper.
The clouds train after GRF impressed me very much. Nevertheless, I am very happy with the result and hope that it pleases you.

Jupiter and Europa – November 29, 2013

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.

Hi all,

On October 12th good weather allowed me to see the rare triple shadow transit on Jupiter, and in addition seeing was excellent. Callisto’s shadow was big and somewhat fuzzy, near the south pole, while Io’s and Europa’s were tiny and sharp, at both sides of the SEB. It was very interesting to see all three shadows move across the planet for one hour! The sketch corresponds approximately to the middle of the event.

Hello friends of the dark side,

after only a few good nights since November, I could say that this winter is really terrible for hobby astronomers in Germany. Yesterday it was my sixth night under clear sky. The temperatures and the cold wind do not just stop. The forecast say, that the sky should be covered by the end of next week and so, this Jupiter is probably the last for me in this season.
In a few weeks he is already too low on the horizon. Then Saturn is the object of the night.

I used my 115/805 TMB Apo (No. 83) and enlarged from 130x to 200x. Towards the end I could even observe the gas-giant with the 3.5 mm eyepiece (230x).
The air was very quiet and many fine details were visible. I hope you enjoy the sketch of our biggest neighbour in solar-system.

It was a great feeling, to catch all these particulars.
Best wishes and clear sky

Io Transit of Jupiter - November 18, 2012

Object Name: Jupiter
Object Type : Transit of Io
Location: Wilp, The Netherlands
Date: November 18, 2012
Media: White paper, graphite pencil, Photoshop

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″.)

Clear Skies,

November’s Jupiter

Jupiter - November 19, 2012


the last few weeks the weather was November-like: much fog and nearly no sun. But on Tuesday we´ve had very good conditions. The sky was clear and no wind. The planetary disc looks total sharp by 230x in the eye-piece. A friend tested his new camera and after this I took my sketch-book and my pencils. We used visual a bino with two 17,3mm Delos.
