Trifid from Roque de los Muchachos

Messier 20
Messier 20

Object Name: M20, Trifid Nebula
Object Type: Galactic Nebula (emission, reflection and dark components)
Obeservation Location: Roque de Los Muchachos, La Palma
Date: 2. June 2011
Media: Chalk pencil on black paper
Observer: Christian Rausch
Telescope: 12inch/F5 Dobson (Hofheim Instruments)

Conditions:
– SQML = 21,7 mag/arcsec*2, seeing good, Temp. +14C, dry
– V=114x (Nagler 13mm)

The Roque de los Muchachos, La Palma, is one of the best places to observe the night sky and main base of the European Northern Observatory.

It took me quite some time to get the sketch, I’ve never seen so much detail within this object before. The sky at the app. 2400m high volcano is amazing, in a few weeks I’ll return there with 2 friends.

This time we’ll also have a 20 inch telescope….

Best Regards
Christian

M20 (BN/DN in Sgr)
Location : Mt. Bo-Hyun, South Korea (1,100M)
Date : May/27/2012
Media : Black paper, White Pastel / Conte
Equipment : Discovery 15″ Dob, Pentax XL 14mm

Hi. ASOD and everyone.

Last May, the latitude of the M20 is enough than I think. So I observe the Trifid nebula. The most distinctive appearance is the asymmetric three-pronged dark lane and the two fuzzy star located in the middle of the nebula.

Stitched Orion Nebula Region

Orion Nebula Complex
Orion Nebula Complex

Object name: Orion Nebula Region
Object Type: Emission Nebulae
Location: Home Driveway
Date(s): 10/8/11 (for left field), 11/23/11 (for right field)
Media: Graphite pencils (varying hardness), black gel pen, blending stumps

Additional Information:

I used my 10″ Orion Intelliscope for these depictions, which were both sketches that were originally done separately, but then later combined into one stitched field.The seeing conditions for both depictions were extremely good, as well as transparency. In the future I may also add additional fields to further-expand the view and area. The nebulae also appeared to have a bluish-greenish tint, which was added in post-processing of the scanned image. The most exciting aspect of these observations were probably the fact that I was peering right into a stellar nursery, a place that stars are beginning their lives. I kept thinking to myself, “if only I had a larger telescope…”

Object Name: NGC 2261(Hubble’s Variable Nebula)
Object Type: reflection nebula
Location: Oderne – small village in southern Poland (picture made during Winter StarParty in Oderne 2012)
Date: 27.01.2012
Media: graphite pencil, white paper, color invert
Telescope: GSO 10” + Meade 5000UWA 8,8mm
Seeing: 3/5 (average)
Transparency: 4/5 (weak)
Outside temperature: -21*C !!!
NELM: 5,8 mag

This sketch is one of two which I made in most difficult weather conditions. The outside temperature was around -21*C so sketching was very difficult 🙂
On the picture one of my favourite objects – Hubble’s Varaible Nebule which looks like flaming star (around R Mon star).
In telescope larger than 10” you can see small traingle shape mist with some faint structure inside.

The Trifid Nebula Close to the Zenith

Messier 20
Messier 20

– M20 – The Trifid Nebula (NGC 6514)
– Emission/Reflection Nebula
– Apparent Magnitude: 6.3
– Itajobi, Brazil
– July 27th, 2011
– 01h00 (U.T.)
– 2B 0.5mm graphite pencil on white paper
– 180mm dobsonian reflecting telescope
– 20mm Super Plossl eyepiece
– Magnification: 54 x
– Seeing: Antoniadi 1 (fine)
– NELM: 5.5

As I’ve already said, July 2011 was a productive month for me. I could observe and sketch many objects as I had never done before. Conditions were exceptional: no clouds, fair wind and pleasant temperature. That night I pointed my telescope to many objects. One of them was M20. Close to the Zenith, it was clearly seen. The dark paths in the Nebula were confusing, though. Only with averted vision I was able to notice the feature thoroughly, so it was a tough job to put it down on the paper. That was my best observation of The Trifid Nebula, I hope you like it.

Clear sky to everyone

Alnitak Region

IC 434, Barnard 33, NGC 2023, NGC 2024
IC 434, Barnard 33, NGC 2023, NGC 2024

Dear ASOD folks,

Here’s a nice sketch I managed to do roughly a month ago.

Objects: IC 434, Barnard 33, NGC 2023, NGC 2024
Object type: various kinds of nebulae (dark, reflection & emission)
Location: Roque de los Muchachos, La Palma, Spain
Date: 12.3.2012
Media: graphite pencil on white paper, inverted on a computer

This sketch was done under the nice La Palman NELM 7.0 sky using a Tokina 300mm f/2.8 photographic lens. With a eyepiece adapter this lens makes a nice roughly 10cm rich field telescope. I decided to take a glimpse at the Alnitak region in Orion to see if there was any chance to see IC 434. Using a H-beta filter indeed revealed the nebula, which complemented nicely the brighter NGC nebulae in the same field.

More careful observation revealed something unexpected to me. There was a round notch in the relatively sharp east edge of the IC 434 precisely at the location of the Horsehead nebula. Cross checking this feature with friends confirmed it to be real. Being able to see the Horsehead nebula with only a 10cm telescope was really stunning. After all, I had grown up always hearing that seeing it requires at least a medium large telescope. This was truly a lesson that aperture isn’t the last word when observing deep sky.

The sketch is a combination of two simultaneous views of the same field. IC 434 and Barnard 33 were drawn with a H-beta filter whereas NGC 2023 and 2024 were drawn unfiltered.

The Seven Sisters

The Pleiades
The Pleiades

Hello.

This is my first sketch presented on ASOD.
Last night I got a clear sky and I started off by looking at one of my favorite objects: M45. The sky was very clear and I was surprised to see a small hint of nebulosity near Merope but it was really faint, almost invisible.
The Seven Sisters plus ofc Atlas and Pleione were shining with a bright light which I tried to mark on my sketch.
I used a 150/1200 Dob , 25mm Plossl Eyepiece, x48 mag (I spread the sketch in two fields, in order to get all the detail.)

Object Name : Messier 45, Pleiades
Object Type : open star cluster
Location : Marosvásárhely, Romania.
Date : 2012.01.21.
Media : graphite pencil on white paper – digitally inverted and enchanced (Autodesk SketchBook).

Clear skies,
