Mars in the constellation Virgo – April 18, 2014

Hello my Friends ASOD, I observed a few days ago from the home to the neighboring planet, with good views, but with the pollution of the city there are no problems for red small. Continents showed well defined in my scope and feel free to make this sketch giving rise to the original on the right side shown in the image and colored on the other side giving a hue similar to that shown by the eyepiece, for further reducing the image and display framing the view. It was a nice domestic observation learning a little more about our sister planet perhaps.

Best Regards.

Object type: Constellation

Location: Bogotá, Colombia

Date: March 29, 2014 1+30 hours

Media: Digital sketch with adobe photoshop CS2, based on a graphite pencil sketch

Equipment: Naked eye view

Seeing conditions: moonless, transparency 2/3, Bortle 8.

Hello all,

I live in a city with around 9 million of people, just located at 4 degrees north from the ecuador. The light pollution is very intense but I feel also blessed that I can see both hemispheres at the same time from my location. I tried to reproduce the bright of my sky in a clear night in Bogotá and the stars that can be seen in it. I feel I´m improving on Photoshop but there is a long way of trying and learning.

Thanks to all for watching!

Clear Skies.

Mars Opposition Watercolou​r

Mars Opposition-April 15, 2014

•Object Name (Mars)
•Object Type (Planet)
•Location (Artignosc sur Verdon – France)
•Date (April 15th)
•Media (Watercolour on white paper, digital tools Paint.Net for the text)

I use my 4” refractor (achromatic) f/10 – 200x to make the initial sketch; sadly the 12” Dobson give me less contrast for this target. Although the full Moon was very bright, (maybe more bright because of the clear sky of my new small village of Artignosc), details on Mars were easy to watch.

After making the first sketch, some locals came in my backyard to have a look, I like that, and sharing beauty is so easy to do.

For this image I use watercolour, on a very humid 300gr paper, I let the pigment floating as I saw the planet colours. The water helps me to give a natural look and feel. Of course this image has no any scientific value; this is just to keep a souvenir of this Mars close passage. Don’t try to compare the little details of my watercolour with reality; I let that to my astrophotography friends, they are so good today!

NGC 3081

NGC 3081

Hi All,

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.

Mars on April 13, 2014

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

The Lunar Eclipse and occultation of April 15, 2014

Aloha!

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

Full Moon on Korean Thanksgiving-September 19, 2013

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.

White clouds on Mars-April 6, 2014

* 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.
Equipment:
– 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.

The Ghost of Jupiter (NGC 3242) Planetary Nebula

•Object Name: Ghost of Jupiter (NGC 3242).
•Object Type: Planetary Nebula.

•Location: San Miguel, Buenos Aires Argentina.

•Conditions: NELM 4.5. Good transparency, bad seeing.

•Date: 23/03/2014 11:00pm.

•Media: HB, 2B, blend stump and PS for color. Averted vision.

•Telescope: Meade LB 12″ on equatorial tracking platform.
•Eyepiece: SW TMB II 6mm and sometimes TV UHC filter.

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.

Galaxy M82 with Supernova SN2014J

Hello,

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.
Sketching:

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.
Telescope: 13.1 inch f/ 5.9 Dobsonian and 6 mm eyepiece 327 X
Date: 02-25-2013, 04:00-06:30 UT
