Returning to the Great Nebula

The Great Nebula of Orion, M42
Sketch and Details by Robert Ignisdei

After long period of my inactivity, I’ve come back to sketching. It has been caused by changing my astronomical equipment.So now, I want to present you my new sketch of The Great Orion Nebula from 8” Schmidt-Cassegrain telescope. It is not so impressive like my former sketches from 12” newton, but lot of details such as a delicate fibres of gas and dust are still visible.

In general, The Orion Nebula was one of my first object, which attract my attention., has becomed a beloved, often observed nebula, observed very attentively, carefully and closely. It is always a great pleasure for me to watch it, to photograph it and finally to sketch this magnificent wonder of our a starry sky.

Yours sincerely,
Robert

Frozen Crab with T600

M1, The Crab Nebula in Taurus
Sketch and Details by Bernard Augier

Messier1

The Crab Nebula

Dobson T600

I was surprised not to found many drawing of the famous Crab Nebula,
espacially with large apperture scope (over 11″).

So I decided to draw my own with a 24″ Dobson F/D 3,3 on equatorial
platform. I’m living in French Alps, in a little village.called Saint
Etienne-de-Tinée.

In fact it takes me two nights on 28 and 29 december 2008. Temperature of –
11°C, Lightly windy, SQM at 21.20 not so good.

It is very usefull to use plenty of various magnification from 100 to 800
and observe without and with OIII filter.

It results (in) plenty of different perceptions and the sketch is really a
combination of all of them.

Without filter the shape of the nebula is smooth and familiar with “gulf” on
the two sides, and a sort of mushroom on the top. With filter, the
perception is surprising with a very “fat” shape on whch you can see the
famous filaments, and the border is ruffled and tormented.

The best wiew was at x200 with OIII.

Thor’s Helmet

NGC 2359 “Thor’s Helmet”
Sketch and Details by Serge Vieillard, translation by Frank McCabe

Thor’s Helmet NGC 2359 in Canis Major

Using an ultra compact 250 mm.Newtonian telescope to observe Serge wrote (Roughly translated from French):

I was staying in the Sahara just south of the oasis town of Djanet, during the 2nd week of January, 2008. The only drawing made of a deep sky object during this tremendous journey was of NGC 2359, although other numerous, spectacular objects were visited. The vision of this beautiful nebula in the T250 with an OIII filter shows a nice structure centered on a rather complex bubble, with filaments and of well defined tormented outlines. This quick drawing suffers from some imperfections, notably the absence of nebulosity that was visible and the misplacement of one of the wings. This object was so beautiful that I promised myself to revisit it again.

Messier’s Candle Flame

M1 (NGC 1952), the Crab Nebula
Sketch by Janis Romer and text by Frank McCabe

Crab Nebula

The excellent sketch above was made by Janis Romer with her Criterion 8″ f/8 Netownian telescope and is the Crab Nebula, M-1 or NGC 1952. This nebula is a supernova remnant with a rapidly rotating central pulsar that can be seen telescopically in the constellation of Taurus near the tip of the southern most horn (Zeta Tauri). The visual magnitude is about 8.5 and the diameter is 11 light years at a distance of 6,500 l.y. The stellar supernova explosion that became the nebula was first seen in the summer of 1054 AD as a daytime guest star. Twenty seven years after John Bevis discovered the nebula in 1731, Charles Messier cataloged it in September of 1758. Charles Messier saw it as an elongated glow in the shape of a candle flame.

A Cat’s Claw in the Bubble

The Bubble Nebula, NGC 7635
Sketch and Details by Serge Vieillard, additional text by Frank McCabe

Serge wrote:
“It was a pleasure to discover the Bubble NGC 7635. A portion of the transparent sphere can be seen with the edge looking like a cat’s claw.”

This beautiful sketch of the portion of NGC 7635 that is known as the Bubble nebula of Cassiopeia was made using an 18 inch Obsession telescope while Serge was in Spain during September of 2007. You can see that the 9th magnitude, young hot O-type star that is shedding its outer surface (stellar wind) and creating this bubble arc is not centered. This is due to the resistance to expansion created by a portion of the surrounding molecular cloud that can be seen glowing in part to the left of the arc. The Bubble is known today to be a diffuse emission nebula and was discovered by Fredrich W. Herschel in 1787.

Wide Field Orion

M42, The Great Nebula of Orion
Sketch and Details by Daniel Stępniak

Daniel Stepniak’s beautiful wide field sketch of the Orion Nebula is a spectacular example of just what wonders await those with even modest apertures. He has submitted several others that will featured on ASOD.

All the sketches were made from suburbs of medium city- Sochaczew,
Poland. Unfortunately, there’s here big light pollution.
I’ve used small newtonian telescope- Synta 114/500 and NPL15mm (33x) and
made it with graphite pencil.
I like sketching during watching the sky. I think it’s the best way to
show what we are able to see using the telescope.

Space Ghost

M1(NGC 1952), the Supernova Remnant in Taurus
Sketch and Details by Przemyslaw Horoszkiewicz, text by Rich Handy

The ghostly apparition of a stellar explosion that appeared in 1054, M1 or NGC 1952, is beautifully portrayed by Polish amateur astronomer Przemyslaw Horoszkiewicz. M1 is 6,500 light years distant and is approximately 10 light years in diameter.

The Finger of God

“The Finger of God”, western Veil complex
Sketch and Details by Robert Twarogal (Ignisdei)

Now I want to present a sketch, that was never publicated in internet. A western part of the Veil Complex, known as he Witch’s Broom Nebula, but I rather prefer other, rare used name, ( less formally ) of this extremely beautiful object: The Finger of God.
A veil nebula especially western part of it, is a marvellous conglomerate of fibres frayed matter.
This complex is a large object, so I usually use my lowest-power eyepiece : Swan 40mm witch nebular filter UB in Newton 305mm
I could spend hours in watching this unusual, extraordinary spectacle, which make me out of touch with reality.

Sublime and Glorious

The Trapezium and Other Bright Stars of the Orion Nebula
Sketch and Details by Janis Romer

January, 1983. Temple University Night Owl, 17 1/2″ Dob. One of those Coulter mirrors*.

You will notice I have not included any of the smaller stars. I was using stars only as reference points for the nebula and simply ignored them. I’ve been tempted to go back and add them in, but decided I liked it better just the way I originally made it, warts and all.

Sketching:
Conte pastel pencils (white, blended greens) on black pastel paper.

*Note: James A. Braginton (Jacobsen), the owner/operator of Coulter Optical (deceased) was the first manufacturer of commercial Dobsonian telescopes. The Odyssey 2 (17.5” f/4.5) debuted in January of 1982. Nearly all of them were made in a small shop in Idyllwild, California. The early ones had well figured mirrors and were very inexpensive. Finished mirror sets were also sold in good numbers. -Frank McCabe

The Veil Revealed

The Veil Nebula, NGC 6995
Sketch and Sketch Details by Robert Twarogal (Ignisdei)

This extraordinarily beautiful sketch of NGC 6995, the Veil nebula, was one of several submitted by Polish amateur astronomer Robert Twarogal (Ignisdei). His detailed yet delicate treatment of this classic emission/reflection nebula is a tribute to his strong observational and artistic talents. We look forward to sharing with you, future postings of Robert’s exceptional entries.
