Astronomy Sketch of the Day
A while back my eye was caught by an image I saw in Mark Bratton’s Herschel book of what turned out to be a galaxy (NGC 3081) in Hydra, at first glance I took it to be a planetary nebula, something along the lines of the Saturn nebula but without the ansae.
Last night having got band from playing my harmonica at the band rehearsal and with a lovely clear sky I decided to take a look, lying pretty close to the well loved Ghost of Jupiter planetary, it was well placed for me to observe on Tuesday evening.
I found this to be a rather unusual galaxy, having a distinct bright central nucleus and a definite outer ring, slightly elongated E-W but basically a ring, some discernible haze outside of the right but no evidence of any structure connecting the ring to the nucleus or of any arms projecting out from the ring, therefore back to my original thoughts that it looked like a planetary nebula with a bright core, stellar illuminated with a fainter outer shell of expanding debris.
Planet Mars on sunday 13th of april 2014, sketch is made five days after mars was in opposition. We should expect that during opposition – april 8th – the smallest distance between our blue and the red planet is achieved. However, this time the two planets elliptical orbit reaches it’s closets distance on april the 14th.
The sketch is made on sunday the 13th of april 2014. The telescope : TEC 160ED, F8 – 11 mm Plossl eyepiece met 2x Barlow lens. TFov 0.3 °. Afterwards adapted in Pro-create en Psd
Tonight after setting up with friends and being thwarted by clouds, I raced home to see if I could still observe part of the lunar eclipse from a different location. Upon arriving home I found it was clear and quickly set up my 15×70 binoculars. I was delighted to see h Virginis just peeking its bright head out from behind the limb of the Moon and quickly started a sketch of my observation. The umbra had almost made it over the last portion of the limb and the remaining edge was brightly lit. The Moon took on a coppery glow and the stars shone nearby that normally cant be observed during full Moon.

Lunar North Polar Region
For several nights this week the lunar North Pole has been tilted more towards earth due to favorable lunar libration in latitude. It has been a good opportunity to view craters such as Whipple, Peary, Byrd and others. I had a clear night with average seeing so I took advantage of the opportunity to sketch the illuminated region near the pole. At my location the Moon was at more than 60 degrees above the horizon which also helped with the time needed to complete a sketch.
Sketching and Equipment:
For this sketch, I used black Strathmore 400 Artagain paper 9” x 12”, white and
black Conte’ pastel pencils and blending stumps.
Telescope: 13.1 inch f/6 Dobsonian and 6 mm eyepiece (333x) riding on an equatorial platform

Last Sep 19th is Korean Thanksgiving Day.
It is the most important holiday of Korea, the date is always Aug 15th in the lunar calendar.
I saw the bright full moon at holiday night.
And jujube tree fruits twinkle under moonshine.
So I drew a picture using my smart phone.
Media : Samsung Galaxy Note 2 (S Note App)
Location : S. Korea
Date : Sep 19th, 2013
* Object Name: Mars
* Object Type: planet
* Location: La Fontasse (Tarn – France) N43.63 E2.35
* Date: April 6th 2014 21h40 UT
* Media: pencil HB + 2B, white drawing paper, scanned + colorized with PhotoPaint
As shown on the detailed view, I experimented the negative drawing with black pencil.
Just by inverting the image, I obtain quite the final result.
I just played with colour and contrast to make it “real”.
Next time I will try to make a negative drawing with blue pencil, to get directly the salmon colour of Mars…
NOTE : The pink colour is real, because of the lunar filter which adds a bluish-grayed hint
This filter provides more contrast and reduces the light intensity.
Conditions: humidity 60%, 12°C, no wind.
– Dobson Orion XT12 (305 x 1500mm => F/D 5)
– Eyepiece Televue Delos 4.5mm (mag x 330)
– Moon filter 1.25″
Excellent transparency and very good seing
Half Moon shining in Gemini
Because of the moonlight, the star party was dedicated to planetary observation.
So I decided to make my first sketch of Mars, as I only once could really see it with details last year.
For the first time I could distinctly see two dark zones : one butterfly shaped (right) and one banana shaped (left)
The sky was good enough to expect to see the north polar ice cap.
I actually saw a scattered brighter spot on the upper part of the disk.
As you never know the orientation of an object in your eyepiece, I decided this was the north pole ice cap of Mars.
Back home, while looking for the name of the dark zones (Acidalia Planitia & Meridiani Planum), I discovered that the north pole was on the right side of the disk.
So, what was this white spot ???
I found the explanation from a recent photo of Mars, on spaceweathergallery.com, showing a white cloud storm, in the same area.
This is how I discovered my new speciality: meteorologist of Mars !
Thanks for your interest.

Hi ASOD! This time I bring you all the Ghost of Jupiter from my backyard. It was a good night except for the poor seeing conditions. Some of the stars are down to mag 13-14 and the nebula, with averted vision, was excellent showing internal details at x254. Days later, at a star party, I could appreciate the full glory of nebula, the central star was like a pin and incredible details were easily seen at x254-x400 (no sketch, sorry!). Hope you like it!
Best regards, Leo.
This is my first ASOD and my first sketch of a moon crater.

Two and a half hours of clear sky at 04.February 2014 were sufficient to hold the SN in M82 and take a long walk on the winter night sky.
After a tough cloud cover and then the mist had dissolved about 21:00 clock, I could start the observation with the TMB 115/805 Apo.
The supernova was a really great thing! Very bright and striking beamed the SN in the “cigar”. After a brief enjoyment, I started with the sketch!
Unfortunately, the review was only mediocre, so blurred finer structures of the galaxy almost. Nice to see was the interruption in M 82 and south two light specks.

Lunar Terminator Near to the Western Limb
On Sunday evening I was getting a wonderful view of the lunar terminator near the western limb just a half day before full Moon. The favorable longitudinal libration of -04° 40’ was creating an opportunity to see craters along the terminator that are often poorly placed for viewing.
With storms on the way from the southwest this was a good evening to attempt a sketch. The calm before the arrival of storms often leaves the seeing fair to good as was the case on this night. Craters such as Vasco da Gama (99 km.), Bohr (73 km.), Dalton (63 km.), Balboa (71 km.) and part of Einstein (175 km.) were all seen. Craters Cardanus (51 km.) and Krafft (53 km.) and the crater chain (catena) between them were in bright sunlight. The views all along the terminator were magnificent.
For this sketch I used: black Strathmore 400 Artagain paper (9” x 12”), white and black Conte’
pastel pencils. In addition a small artist’s brush and powdered Conte’ white crayon was used for blending. Contrast was slightly increased (+2) using a scanner to better match the original.

Greetings to all visitors of this page. Pedro Villamiel Alcorcón, Madrid February 1 2014
Good afternoon all,
I had to push myself last night to grab an observation through a clear sky window. Family taxi duties, followed by a music practice session at a friend’s house saw me return home under a cold clear sky with a frost already forming. I had intended to be in bed early as I had to be up at 5am for work, but! I couldn’t pass by a chance to grab a sketch before the moon rose could I?
I had nothing planned, so I looked through the Arp catalogue for something new in the vicinity of Orion, there were a few Arp’s that I hadn’t got but they lacked any wow factor so I looked to Herschel’s NGC observations, noting that NGC 1954 looked both attractive and a little different, this lay in Lepus beneath the giants feet. I star hoped to this mag 11.8, 4.2’ x 2.0’ spiral, it appeared rather faint on the monitor, I adjusted the monitor controls to maximise the contrast and the remote camera controls, I then went out into the observatory and lowered the southern observing flap, as this was cutting the 500mm aperture down by around 50%. This improved things but it was by no means bright all considerable detail was displayed. I drew in the main field stars and when I came to work on NGC 1954 itself I turned all the lighting off to elevate the contrast still further in an endeavour to pick out all the structure that I could. A smaller companion galaxy NGC 1957 which appears as an extended amorphous fuzz to the upper left in my sketch is a more distant mag 14 spiral.
Once my sketch was completed I was quite pleased after my initial disappointment at the targets lack of ‘star’ quality. Taking my SQM reading of the observation area, low in the south towards London showed as just 19, compared with 20 overhead, however the Moon was now above the horizon to the east.
In all a worthwhile observation, which had taken an hour and resulted in a reasonable sketch of an interesting and new galaxy for me.
Clear Skies to you, Dale

Messier object 45 “Pleiades” 30 ‘of arc in my binocular field of view of 5 ° with acceptable transparency.
It’s my first drawing with digital art.
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.
Thanks for nice comments!
