Occultation of Saturn by the Moon

Here join a watercolour I made while Saturn just leaves the very young moon.
That was a very nice spectacle indeed!
The original sketch was done in B&W on white paper; the small brilliant point on the very end of the moon croissant was used to define the Saturn disk intensity.
The colours were added in my workshop and the inverted while scanning.
During the emersion (17:17 UTC) the moon was less than 4° up my horizon and the sun was only 6° behind. So the sky was still clear.
The observation was made with a 102 f/10 refractor and a 10mm Delos EP, no filters.

Clear sky to you all !

Brilliant Saturn at the Dark Lunar Limb

A conjunction of the Moon and the planet Saturn - September 27, 2014
A conjunction of the Moon and the planet Saturn – September 27, 2014

Aloha!

I had plans to go to the summit of Haleakala to observe the occultation of Saturn by the Moon, but clouds and wind kept me closer to home. I was delighted when a patch of sky opened up and I could observe the wonderful phenomenon from home.

As I was observing Saturn get closer to our Moon I was struck by how small it appeared in comparison, appearing the size of some of the smaller lunar craters. I began sketching in the details of the Moon and noticed a few stars I wanted to include. I needed to do some erasures because one of the stars was occulted ~15 minutes before Saturn, an unexpected treat. Once Saturn made it to the limb I could not clearly time the initial ingress as conditions began to deteriorate. It was however brilliantly lit in comparison to the dark lunar limb. I noted time as 19:41:36 HAST when all evidence of Saturn disappeared. My sketch is as Saturn had partially slipped past the limb. I was unable to view egress as the Moon had slipped behind clouds by this time.

– Object type: planet
– Location: Tarján, Hungary
– Date: 25.7.2014., 19:21-19:37 UT
– Media: sketch with graphite pencil, finished with a drawing software

After weeks of cloudy weather I was finally able to make a sketch about this beatiful planet.
The drawing and the writing of my notes took approximately 15 minutes. The skies transparency was quite good, but the air conditions were bad, so I had to wait long to see some details. I used a 102/1000 Celestron OmniXLT refractor and 170x magnification during the observation.
After the sketch was done I watched some other object on the sky, so I finished my draw at home, using my laptop.
I hope you like it.

From July 4 to 8 Moon played with planets. From a purely astronomical point of view the Moon showed us some beautiful conjunctions, Mars, Spica and then Saturn. By the way the game was a little complicated with the clouds. What a season!
On July 5, the moon was still visible behind heavy clouds. The next day, I have not even been able to detect the moon light ! I had to invent the sky. July 7, when the Moon approaches Saturn, clouds returned to disturb the magic of the moment. I’m a bit fed-up about this weather, and I think not being alone!
The advantage of astro-artist on the astro-photographer is that we can complete our design. This time I have to add the missing lunar position on the view. And to capture those irritating clouds, I painted a hazy wash around the Moon as was the case on July 5.
The small hilltop village that served as a foreground is called Artignosc-sur-Verdon. I confess to being quite happy by this view. Artignosc is just halfway to two now well-known astro-spots “The Blaque” in Varages and the OAB in Bauduen. And ‘cause we are nevertheless in Provence, believe me above the clouds the sky is very dark!
Still … what a season!

To do this watercolour, I went out on my terrace at ten PM every night, sometimes before the storm, sometimes after and once during, being passionate or you do not. Every time I sketched some sketches in a hurry, and took two or three pictures allow me to keep the shades. At the workshop, I started by gathering the different positions of the stars and their locations relative to the village. In less than a week, only the Lunar race was noteworthy, Mars and Saturn are much quieter than the stars. Then I realized in reverse mode (colors and contrast) this watercolour. I just had to scan my sheet and reverse the colors.

Saturn – May 9, 2014 (above) and April 30, 2014 (below)

Desire to see the more deep ancient lunar horizon landscapes lead me to build more larger instruments,

since last autmn,s first light I have 10 nights observations with my homemade 13″ refractor [lens from China 320/3700] which has a comfortable fixed focuser in equartorial mount.

With a glass 5 times more heavier than 8″ lens this 13″ shows far majesic views of the moon and planets than the superb 8″…… and but at least on the moon limbs , the details seems to equal…. yet.

Yesterday, on a good seeing night , I could see a great view of the saturn that I have never seen yet. —————-

Hey ASOD!

I send you an old sketch of a occultation of Saturn by the moon!

This is the most interesting occultation of Saturn I have seen.

The rings were wide open and the sky was clean.

I used a stop- clock for the timing of this event. Info on the sketch!

For my sketch, I used color crayons on black paper.

Location: Trondheim, Norway.

Best wishes and clear sky from Per-Jonny Bremseth.

Saturn – May 1, 2012

Hi, I send my sketch of Saturn. The Saturn is my favorite of the planets. I live in Psary in Poland. The sketch I did on the night of 30 April to 01 May. I had a very good view of the scale of 8/10. Saturn showed a lot of detail. You could see the famous Cassini gap. The atmosphere was very calm and did not cause degradation of the image of this interesting planet.
I was using 200x magnification. My telescope is a Newton 200/1200. I used a pencil to sketch 2B and white paper. Using GIMP I added a black background, which gives a realistic picture of Saturn with a telescope. GREETS 🙂

Hi, my dear friends. One year later I am back with a Saturn sketch.
I made this sketch in April this year, but only now I found some time to scan and submit it. I hope you astronomers and enthusiasts enjoy.

No clouds, no Moon and no wind. The night would be perfect, wasn’t by the seeing (Ant. 2) and the city lights (NELM 4.0). I decided to observe from my backyard instead of moving all the equipment to the farm.
Despite the limitations, the favorable position of the giant planet revealed several typical features, like Cassini Division, rings’ and globe’s shadows on each other and five of its numerous moons. C-Ring was not visible.
The five visible moons were Japetus, Rhea, Tethys, Dione and Titan.

Clear sky to everyone!

Greetings from Brazil,

Saturn in Good Seeing

Saturn - July 19, 2013
Saturn – July 19, 2013

Hello,

Persistent cloudy, rainy weather here in the Appalachian Mountains has prevented me from seeing most of the best part of this Saturn apparition, but the clouds finally parted briefly earlier this month and allowed this view of the ringed world.

Because Saturn is now well past opposition it is lower in the sky at twilight and well down in altitude after dark, making good seeing imperative for a decent view. I was fortunate this evening because the air was fairly turbulent at sundown when Saturn was still above 30 degrees altitude but got steadier after dark, even though the planet was much lower.

Saturn’s rings are currently tilted at about 17 degrees which gives the observer a good view of the different rings and their features as well as the Cassini Division all the way around.

I got a good look at the North Polar Cap (NPC) but was unable to detect visually the distinct hexagonal shape visible in images.

Four moons were attending Saturn that I could see–Titan, Rhea, Dione, and Tethys. The fifth moon, Enceladus, was there too but hiding in the glare of the rings.

Saturn, among the most beautiful of celestial objects, was a pleasure to observe. There is still time to take in its beauty before the end of this apparition so good luck with the weather where you are!

I made this observational field sketch in my observatory using a template on white copy paper. Pencils used were 2B and HB graphite, charcoal (for the shadows), and a white Derwent Graphtint pencil (for the Crepe Ring).

Hello nighthawks,

so this is the last Saturn for this season.In the next few weeks, he is no longer very high above the southern horizon. Unfortunately, in Germany the weather was this year very changeable. There are seldom good observations possible, but on 06. June 2013, the conditions were very good and I decided to sketch the beautiful ringed planet without a template. The Plant was 0.57 magnitude brightness and the diameter was 42,8″.

After almost an hour I was happy with the result and I hope you like my second Saturn freehand drawing this year. The main difficulties are to bring the ring system faithfully to the paper.

Always clear skies

Saturn and Enceladus – June 20, 2013

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.

I made this sketch of Saturn from my backyard on April 23th, but left it lying around far too long to finish drawing it from memory. So tonight I took the opportunity to do some more observation and complete the sketch. Seeing was bad as Saturn hovered low above Maastricht city. The moon probably is Tethys.

Notes:

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.

Hello friends of the planets,

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. 😉

Saturn - July 5, 2012

Despite the fact that from day to day Saturn is lowering on the sky I decided to make a new sketch of this planet. I was sketching it in December so desire was double. Saturn always looks beautiful especially when its rings are at the appropriate angle like now. But of course that angle is still increasing. On my sketch I tried to show how the planet looks in the eyepiece. Have I done it right? Judge by yourselves.

Last night I wanted to make a sketch of Saturn, mostly to capture as much moons as possible through my old 75mm f/15 Polarex/Unitron refractor. After 45 minutes of sketching at 200x with pastel pencils on black paper, Saturn was pretty much done (although I found it surprisingly difficult to draw a good ellipse for the rings), and just when I added the easily visble Titan, I heard some droplets on the trees next to me and felt something on my head: RAIN! I immediately covered the pastel sketch witch my hand and rushed inside my shed. After the sketch was save I pulled the telescope out of the rain. The most abrupt ending of a sketching session ever! I had completely missed the incoming clouds while viewing through the eyepiece.

Anyway, both the sketch and the telescope survived. Sadly with only one moon observed: Titan.

Clear skies and kind regards,

I spent that whole night observing the sky from backyard, and one of my targets was Saturn. Despite the clouds, the seeing and transparency were great, so I could see Saturn like never before (450x without any loss). Both the shadows of the rings on the globe and the shadows of the globe over the rings were clearly seen, splitting one another. The Cassini Division could be seen in both ends of the rings, but the difference in the outer ring color was not notable. A dark stripe crossed the planet, fading yet very remarkable. Another shy dark stripe intended to follow the first one, however was not able to cross the hole bright disc. Two of its moons were visible. In fact, Iapetus was probably visible too, however it was far away from the planet, and I missed it.
The next night it rained a lot, and I spent it doing something else. The following three nights the sky was clear again, and I could observe Saturn and its moons. I made this four sketches (in second picture) to show the dance of the moons around Saturn, all made at the same hour, during four days. Follow the sequence:
a) December 27, 2010
b) December 29, 2010
c) December 30, 2010

Burning Candles at Both Ends

Clear skies and a prominent day-11 moon on the evening of 16th December had me out really enjoying sketching; it wasn’t too cold (to begin with), the skies were clear, the target was high and I had plenty of time…..all a rare occurrence.

I sketched one of the most architecturally pleasing parts of the moon; the Sinus Iridum, which is a large crater/small basin with a partially flooded rim.

Of the two promontories, the one on the right (Promontorium Heraclides) is also known as the moon maiden, because at certain times it resembles the profile of a lady, with her long hair falling away off her shoulders. Also visible are the wrinkle ridges which might be traces of the buried rim, and craters Bianchini, Maupertuis, La Condamine and Bouguer.

Awaking on 17th at 4am with busy thoughts, I decided that viewing Saturn would be better than attempting to get back to sleep. And so it was.

I was surprised by quite a lot. The rings had opened up quite a bit since I saw them last spring. Not being close to opposition, the planet was quite small and I couldn’t see much detail on the planet itself. Only one moon was obvious; Titan predictably. With effort, another moon could be viewed roughly forming a right-angled triangle between Titan and the planet; it’s the faint spot at middle-left of the picture. This turned out to be Iapetus, which was pleasing because I haven’t seen that very often. It was new for me to see a moon so out of plane with the planet and the rings as last year they were mostly in line. It was good to see such old friends again.

Venus, Saturn and Handful of Frost

Hello!
Last night I and my Friends we have a great observation night in Oderne, in south Poland – beautiful place among Beskid mountains. We have very good, clear sky but there was very chill. We have very low temperature at night. About -20°C (about -4°F). In central Europe during the Winter, it is nothing strange. But it is necessary to be a tough to make all night observations in this conditions 😉
After many hours of the good observations we take a little nap. We have resumed our observations at 4 AM to get the first Venus and Saturn since few months.
There was intense, severe frost.

Object: Planets Venus and Saturn
Scope: SCT 5″ with SW UWA58 9mm
Time and date: December 5th, 2010. About 4:00 AM
Place: Oderne, Poland
Weather: Clear, dark sky. Heavy frost.
Technique: Graphite pencil
Tooling: Some correction with PhotoShop
Observer: Aleksander Cieśla (Wimmer)

I have a interesting foto from that observations.
There was really heavy frost. After all my equipment was operating quite good 🙂 There was strange noise from motors of my Celestron SLT mount, like howling 😉 But all night long it was operating correctly. I have little problems with corrector plate of my C5 SCT too, but dew shield works not bad. Most problems we have with the eyepieces. Puting the eyepiece to the poket at several minutes – that was an easy solution of this problem.
During that night my equipment looks like that: 🙂

Thank You, and sorry for my bad english.

Saturn – Large Sketch from Observation Through the Telescope With Artists Conception Below
By Mark Seibold

From Sandy Oregon, 30 miles east of Portland, at the home driveway – Saturn Observed February 28 ~ March 2 Through 10.1″ Newtonian- Large Pastel Sketch produced:

I observed Saturn through my 10.1″ Newtonian at medium to high power magnification (120X ~ 240X) on several evenings last week, in effort to see some detail in the rings and surface cloud banding. Seeing was medium to marginal at times through the evenings. Using Sol Robbins template and other images from the web to accurately proportion the rings, I rendered this 19” X 25” pastel impression showing about what is seen in a good medium telescope if one stands back say 25 feet from the full image on a standard computer screen. Saturn’s disc was sketched at 7 ¾” at the equator. The Cassini division was easily visible and the crepe ring only hinted at high magnification at 240x through a 5mm Super Plossl eyepiece through my 10.1″ f/4.5 Newtonian-Dobsonian telescope with average seeing conditions at times with glimpses through steady atmosphere.

The foreground was quickly added from imagination for depth and drama as a final touch, which seems to captivate a view from one of Saturn’s moons, possibly Titan with a suggestion to an ocean-scape.

The sketch was photographed with a Sigma 35mm DSLR under white balanced studio lights.

Sketch and Details by Serge Vieillard

On March 8, 2010, it was off to the Observatory of Paris, on the venerable 380 mm glass (to see “Mars). We passed under the plane of the rings and they are currently well closed and gray in color. The crepe ring is thus particularly obvious. The vision is very white, very bright, with a yellowish and suspicion sometimes of a greenish tinge. G 750X.


Saturn occultation by the Moon

Moon-Saturn Occultation
Saturn occultation by the Moon
Sketch and Details by Fred Corno

Please find attached a drawing of the Saturn occultation by the Moon occurred on the 22nd of May 2007 from approx. 19.23 through 20.34 UT.
The occultation was visible from Europe, and I recorded the event in a drawing made at the eyepiece of my 5” apochromatic telescope.
Drawing was prepared in advance with a large disk representing lunar surface, where terminator position and main features were marked in graphite pencil.
During the event, I marked at 19.23 (point 1), 19.28 (2), 20.34 (3), 20.35 (4), 20.38 (5), 20.40 (6) the position of Saturn, drawing the shape of the planet.
Eventually, black for the unlit part of the moon and the sky surrounding it and the colors for the planet were added.
As Saturn was the most amazing feature of the event, unconsciously I drew it larger than its real size: nevertheless final effect of the sketch finely matches what remains in my memory of that wonderful night.

Best regards.

Fred


Saturn in mid-March 2009

Saturn

Planet Saturn and moons: Tethys, Rhea and Dione
Sketch and Details by Frank McCabe

With the rings nearly edge on but opening just slightly, I felt it was time to record another sketch of the ringed giant. To begin the sketch I used a white Conte’ crayon and compass to draw a circle on black paper. I then used a mechanical drawing tool called a French curve to convert the circle into an ellipse after plotting a few points to create an equatorial bulge. When the shape looked alright for the bulging globe, I sketched the rings and then the globe while looking through a 4 mm orthoscopic eyepiece (magnification 362 x).

I observed Saturn for 40 minutes before beginning the sketch which took about 50 minutes to complete. I made note of the positions of the moons I could see and added Tethys (10.3) and Rhea (9.9) to the west of the planet and Dione (10.6) to the east. Titan was well beyond the planet to the west and Iapetus was visible above the planet to the south. Both of these moons were beyond the boundaries of the sketching area. The planets equatorial zone and the north and south temperate zones were bright and distinct. The darker regions over the remainder of the disk were less distinct through the polarizing filter I was using.
Although the transparency was only average at 3/5, the seeing however was exceptional at Pickering 8.5. The stars were rock steady for long intervals.

For this sketch I used: black Strathmore 400 Artagain paper, 6”x 16”, and white and black Conte’pastel pencils and Conte’ crayons. The globe of Saturn is about 2.5” inches in diameter. Brightness was slightly decreased (-3) and contrast increased (+3) after capturing the sketch using a digital camera.

Telescope: 10 inch f/5.7 Dobsonian and 4mm eyepiece 362x, single polarizing filter
Date: 3-15-2009 4:20 – 5:10 UT
Temperature: 0°C (32°F)
clear, calm

Two Lords of the Heavens

Comet Lulin

Comet C/2007 N3 (Lulin) and Saturn
Sketch and Details by Leonor Ana Hernández

COMET LULIN c/2007N3

The medium used: graphite pencil.
Negative image.

The equipment used: 12×80 Binoculars (Field 4,2º)

Date: 23-02-2009
Place: Cuerva (Toledo, Spain)

The night was explendid, clear and cold (1º C).
The Sky Quality Meter (SQM-L) shows 21,17 mag/seg arc^2

The comet and Saturn was in the same field of view, separated 2º aproximately. At 23:30 TU the coma was located between the stars HIP55574 and HIP55467 of Leo. The coma´s diameter fills the space between them completelly.
The tail was wide close to the coma but very thin at the end.
Quite visible and noticeable. The tail points to 80 Leonis and exceeds it with averted vision.
The nucleous was intense but not a like-star.
Saturn was fantastic with a pale yellow light and the thin ring that crosses the planet, like a cutter line. And Titan very close…

Unforgetable night!

Comet Lulin Meets Saturn

Saturn and Lulin

Comet C/2007 N3 (Lulin) and Saturn Conjunction
Sketch and Details by Jef De Wit

First my big appreciation for the website. I was a fan of APOD for years and discoverd ASOD only two month ago. Even the members of my astroclub specialised in sketching didn’t know of the website! I try to motivate them to send some of their best pictures, but I think I have to give the example first. I hope you like mine sketch.

The weather in Belgium was (and is still) very bad. I tried to see Lulin for several nights without any result. The 24th this month there was a brief opening around 3.30 (local time) in the clouds for about 20 minutes. I was on holiday and had only my binocular (7x50mm) with me. The observation was made from a balcony on the 10th floor. I had to lean – not without any danger – over the realing to see the comet, so I couldn’t install my tripod. To bad, because the binocular handheld there were no details vissible. The comet was a round, uniform spot in the sky. But that doesn’t matter, the conjunction with Saturn was a beautiful sight. I made a sketch and went outside in the hope to install the tripod. But the time I arrived downstairs the clouds were again omnipresent.

Object name: C/2007 N3 (Lulin)
Object type: comet
Location: Oostende (51° North 3° East, Belgium)
Date and time: 24 februari 2009 2.30 UT
Instrument: handheld binocular 7 x 50 mm
NELM: 4
Medium: graphite pencil (2B and 8B) on white printing paper, scanned and colours inverted

Saturn’s Rings Nearly Edge On

Saturn and moons in mid February 2009

Saturn in mid-February 2009

While I was awaiting the waning gibbous moon to reach a higher position in my southern sky, I decided to try my hand at a Saturn sketch. With the rings nearly edge on I find that the ring system is much less intimidating to portray. To begin the sketch I used a Conte’ crayon and circular compass to draw a faint circle on black paper. I then grabbed an old mechanical drawing tool called a French curve to convert the circle into an ellipse after plotting a few points to create an equatorial bulge. When the shape looked alright for the bulging globe, I sketched the rings and then the globe while looking through a 6 mm eyepiece (magnification 241x). Saturn usually give me trouble while sketching, so after 15 minutes I found myself making too many errors so I erased the sketch and started over on the reverse side of the paper. The second attempt went better and after an hour I considered the planet sketch finished. I made a note of the positions of the moons I could see and added Tethys (10.3) to the west of the planet and Enceladus (11.9) viewed intermittently and Dione (10.5) to the east. Titan and Rhea were visible in the eyepiece at low power but beyond the margins of the sketch. The planets equatorial zone and the north and south temperate zones were bright and distinct. The darker regions over the remainder of the disk were less distinct through the polarizing filter I was using.

Sketching:

For this sketch I used: black Strathmore 400 Artagain paper, 7”x 9”, and a white Conte’pastel pencil and Conte’ crayons. The globe of Saturn is about 2.5” inches in diameter and was done using sharpened pieces of Conte’ crayon. Brightness was slightly decreased (-3) and contrast increased (+3) after scanning using Microsoft Office Picture Manager.

Telescope: 10 inch f/5.7 Dobsonian and 6mm eyepiece 241x, single polarizing filter
Date: 2-13-2009 5:25 – 6:45 UT
Temperature: -2°C (29°F)

Awaiting the Opening of the Ring Plane

Saturn

Saturn, February 13, 2002
Sketch and Details by Per-Jonny Bremseth, text by Rich Handy

Per-Jonny Bremseth’s beautiful 2002 rendition of Saturn with wide open rings contrasts with it’s current almost closed appearance. The nearly edge on view of the rings we have now will, over the course of a few years, open the ring plane up again for our appreciation of it’s wonders.

This splendid pair of color pastel sketches captures many of the main attractions of Jupiter and Saturn as seen at the eyepiece in late spring of 1986. At that time Saturn was in the southwestern sky while Jupiter was in the southeast. – Frank McCabe


Saturn at the Beginning of 2009

Saturn with moons at the beginning of 2009
Sketch and Details by Carlos E. Hernandez

I made an observation of Saturn on the first day of the new year (January 1, 2009) at 07:30 U.T. using my 9-inch (23-cm) F/13.5 Maksutov-Cassegrain at 163x and 344x under clear and steady seeing conditions (S: 7/10, T: 5/6). It was exciting and strange to observe the ringed planet with such thin rings.

My wide field observation made at 163x depicts Saturn at the center with five satellites visible. The satellites, from following to proceeding, are Titan (8.4m), Enceladus (11.7m), Dione (10.4m), Rhea (9.8m), and Iapetus (11.1m).

Sketch and Details by Carlos E. Hernandez

At a higher magnification (344x) Saturn exhibited detail over its globe. The following is a description of the visible regions of the planet;

South Polar Region (SPR) was dark to dusky (3-4/10) with a dark (3/10) central core.
South Temperate Zone (STZ) was shaded to bright (6-7/10) and mottled.
South Equatorial Belt (SEB) appeared dark to dusky (3-4/10) with a thin, bright (7/10) zone over its center.
Equatorial Zone (EZ) appeared bright (7/10) with no detail visible within.
Ring Shadow (RS) appeared very dark (2/10) and thin
North Tropical Zone (NTrZ) appeared shaded to bright (6-7/10).
North Equatorial Belt (NEB) appeared dusky (4/10) and thin.
North Temperate Zone (NTZ) appeared shaded (6/10)
North Polar Region (NPR) appeared dark to dusky (3-4/10)

The rings appeared dusky (4/10) without any detail visible over them.
