Big Star’s Carpet

NGC 5139 (Omega Centauri)
Sketch and Details by Laurent Ferrero

Object Name : NGC 5139 (Omega Centauri)
Object Type : globular cluster
Location : Corral del Niño, Tenerife, Canaries islands
Date : april 2009

Magnificient globular cluster which covers a large scale in the eyepiece at 68x. The cluster looks like at big star’s carpet with little dark holes and no central condensation. The global shape of the object is clearly oval. The observation was made with my Intes 6″.

Best regards,

Laurent

Mars – January 12, 2010

Mars – January 12, 2010
Sketch and Details by Szabó Ádám

Location: Hungary, Hódmezővásárhely
Date: 12th January 2010
Medium: digital drawing
Instrument: 6″ f/5 Newton (Celestron Omni XLT) @ 250× magn.
S:8-9 T:3-4

This is my second try to make a digital drawing about Mars. The pencil sketch for this drawing was made between 01:30 and 01:50 UT. I used a 14 color palette and a variety of partially transparent and different sized “brushes” for the digital drawing.

Best regards: Ádám

Three Parts of the Orion Molecular Cloud Complex

Messier 78, NGC 2071, NGC 2067
Sketch and Details by Serge Vieillard

Another sketch made on the second night of observing at La Palma, and with the 16″scope is the beautiful, bright and diffuse reflection nebula M 78 (left center). Other parts of the Orion molecular cloud complex included in this sketch are NGC 2071 far right and below and to the right of M 78 is NGC 2067. This was another quick sketch of the “splendor of Orion” as Serge calls it.

Mars – January 10, 2010

Mars – CM 262 – January 10, 2010
Sketch and Details by Frank McCabe

Mars: January 10, 2010

It was a cold, mostly clear, moonless, night with Mars high in the southeastern sky. Mars was very bright at visual magnitude -1, 98% illuminated and 65.1 million miles from us. The visual diameter of the planet was 13.4″of arc and the central meridian was at 292°.
The first sketch, a graphite drawing, was made at the eyepiece over a one hour interval. When I returned indoors I redrew the sketch in color pencils. When the second colorized sketch matched the eyepiece sketch I stopped and considered it complete.
The seeing was about average (Antoniadi III). Mars is inverted in the sketch and matches the Newtonian view with the north polar cap down and the preceding side to the left.
From top (south) to bottom (north) along the meridian I was able to see with certainty Hellas, Iapygia Viridis, Syrtis Major, Casius and much of Utopia. Also visible in the southern hemisphere were Mare Tyrrhenum, Mare Sepentis, and part of Sinus Sabaeus. In the northern hemisphere I could see intermittently Nodus Alcyonius and Boreo Syrtis.

Sketching:

White sketching paper 8″ x 11″; HB graphite pencil, blending stump for blending orange, brown and yellow Crayola pencil shavings. No adjustments were needed after scanning.
Date 1/10/2010 – Time 3:45-4:45 UT
Telescope: 13.1 inch f/6 Dobsonian and 6mm eyepiece 333x
An UltraBlock Narrowband filter was helpful with some of the fainter features.
Temperature: -17°C (1°F)
clear, calm
Transparency 4/5
Seeing: Antoniadi III

The tan image is my sketch of the remaining Sunspot Group 1040 seen in white light
Conte chalks, pastels/Artagain paper, LUNT Solar Systems B1800 Cak Filter module on an Explore Scientific 127mm ED refractor.
I would strongly encourage all the solar photographers out there to give sketching a try. It gives you unique insights that cannot be caught on film. Thanks Stephen Ames and Erika for inspiration.

Messier 46 and NGC 2438

Messier 46 and NGC 2438
Sketch and Details by Paul Byrne

This was rendered with a fine point pen for the stars, the nebula was sketched with charcoal and blending stump.

I observed the cluster through a 305mm Orion Newtonian and 13mm Nagler. The date was 9th January 2010 at 01.12 UT, it was very cold with a sharp northerly wind, the temperature was well below freezing.

The nebula was not visible until an O-III filter was inserted and it popped into view.

Thanks for your time.

Biting the moon on New Year’s Eve

Partial Lunar Eclipse
Sketch and Details by Peter Mayhew

Object Name: Partial Lunar Eclipse
Object Type: Lunar
Location: York, UK
Date: 31st December 2009

In the UK, New Year’s Eve coincided with a tiny partial lunar eclipse. However, this was my first such event since catching the astronomy bug, so I was keen to see it. The weather was mixed, but by the time I had the scope out (18:37UT)(150mm f8 Dobsonian, 25mm eyepiece) the event was underway with a penumbral shadow visible on the south-eastern portion of the moon. Clouds obscured the view for most of the time but there were enough breaks to give a decent view of the Umbra at about 19:20UT, until about 19:45UT, when the clouds obscured the view completely.

I made my sketches using graphite pencil on white paper, and scanned the images, and inverted them to give the naked-eye aspect, with north at top.

A happy new year to all at ASOD!
Peter

A First Sketch of Copernicus Crater

Copernicus Crater and Surroundings
Sketch and Details by Ferenc Lovró

This is my first ever Moon-sketch, displaying craters Copernicus, Fauth and Gay-Lussac with some other sub-craters and domes not noted on the sketch. This is my actual sketch done at the eyepiece, no alterations were made after manually or digitally, other than resizing. It took about 45 minutes to finish, and I’m quite satisfied with it, although I’ve found that sketching the Moon is indeed very hard and very different from sketching deep space objects. Perhaps I should not finish Lunar sketches at the eyepiece but create only drafts with different markings for different shades and create the actual sketch in the warmth of the room. As an additional difficulty, the sky was 100% covered with a thin layer of cloud which kept the image in constant change, only 1 or 2 stars were visible here and there. Moon phase was about 69%.

Equipment: 12″ f/5 Newtonian
