Hello,

i send you my latest h-alpha-sundrawing from 27.11.2011. I send you the positiv and the negativ
version of my drawing.

Object Name: Sun
Object Type: Star
Location: Freising-Lerchenfeld, Bavaria, Germany
Date: November 27, 2011
Media: graphite pencil, knife, digital tools (Minolta Dimage Z2 Camera)
Time: 10:50 – 13:15 MEZ

Telescope: Coronado PST (40/400mm)
Ocular: 9mm SW

My webside: www.dersonnenzeichner.de

I use a drawing pattern with lightgray sun. I draw the prominences, sunspots and
filaments with graphite pencil. For the active regions and flares i use the knife to
scrape the gray color off. On this away I can hold finest details.

Kind regards,

Michael Wendl

Pleiades

The Pleiades
The Pleiades

Location: Pesaro, Italy
Date: 25/11/2011
Media: graphite pencil, color inversion with Gimp,
Telescope: 130mm f/5 tabletop dobson.
Eyepiece: 32 mm Plossl

The weather was quite moisty but the sky was clear. I went out searching for M42, but Orion was still covered by the roofs while Pleiades were high in the sky, so I decided to sketch them instead while waiting for Orion. Too bad no nebulosity was visible under such light polluted sky with such a small instrument.

Rosette Nebula

Rosette Nebula
Rosette Nebula

“Rosette Nebula” is a large emission nebula located in Monoceros, around an open cluster NGC 2244. This is a classic star forming region, where stars from the open cluster were formed from the nebula’s material.

The cluster in the middle (NGC 2244) is very bright, and easily noticed with a naked eye under dark skies. However the nebula around it is a tougher target. It’s large, faint, and best viewed with moderate aperture and wide angle eyepieces (2.25 degrees field of view in this case). UHC filter helps a lot. The nebula has roundish structure, with diffuse and irregular edges. Under dark skies it reveals a complex structure, with a large “black hole” in middle of it, where the cluster resides. Most of it’s stars are blue or white, except the brightest yellow star on it’s edge (12 Monoceri).
At the north-east (top-right in this drawing) there is a faint, elongated open star cluster NGC 2252.

Object Name : “Rosette Nebula” (Caldwell 49) and NGC 2244
Object Type : Nebula (HII region) and open cluster.
Location: Negev desert, Israel, ~6.6 mag. sky.
Date: 25-26/11/2011 ; 03:30.
Instrument: 200mm F/5 Orion (US) Newtonian, Hyperion 31mm, UHC, 32X, 2.25° TFOV.
Media Graphite pencil sketch on a white paper. Inverted and processed in Photoshop.

NGC 6520 and Barnard 86

Object : NGC 6520 & B86 (Ink Spot Nebula)
Object Type : Open Cluster & Dark Nebula
Location : Haleakala Summit, Maui, Hawaii
Date : 7/3/11 11:20pm
Medium : Graphite pencil on white paper

I found this object by accident while locating another object & could not take my eyes off it. The open cluster appears three dimensional next to the stark black dark nebula. I used PhotoScape to invert to black, and to sharpen up some of the stars & color the yellow star in the most western section of the drawing.

Thank you for your consideration!

Dark side Moon and Tycho crater

Moon and Tycho

Dear artists:

Last night, after heavy rain, I had time to observed the sky. The Moon was full. The Tycho ( right crater ) wasn great but something
fascinated me… I don’t know what was the name of crater. I do not observed this crater until know. Probably, this crater observed because librations…

Location: Iran/Tehran.

Same Sombrero, Darker Skies

Messier 104
Messier 104

Object Name: M 104 (The Sombrero Galaxy)
Object Type: Galaxy
Location: Itajobi, SP, Brazil
21º19’S / 49º03’W / +450m
Date: 2011, July 26th
Time: 23H30 (U.T.)
Media: 2B 0.5mm graphite pencil on white paper, scanned and inverted
Telescope: newtonian 180mm f6 dob mount
Eyepieces: 32mm, 10mm and 6mm (all Super Plössl)
Seeing: Antoniadi I (excellent)
Observer: Rodrigo Pasiani Costa
Overall weather conditions: no clouds, no wind, about 20ºC and low humidity
Site conditions: farm about 3 miles from a small town, dark, low light pollution, naked eye limit magnitude 5.5

When I sent you my first Sombrero sketch, in December 2010, I promised to sketch it from a darker place to see the difference, so that’s it. If you search for the sketch called Happy Ending (M104 The Sombrero Galaxy) you’ll be able to see the huge difference between downtown and a dark place. Past July was a great month for me, I was allowed to observe many objects, including this amazing M 104. It was the first time I’ve seen it so bright and so detailed. Sombrero was 34º above the horizon, right toward the West. With direct vision only the nucleous was visible, however under averted vision the galaxy showed all its spell, as shown in the sketch. I hope you enjoy it, it has already become one of my favorite sketches.

Best regards, and clear sky to everyone!
