Great Nebula in Carina

Carina Nebula - NGC 3372, NGC3293 and NGC 3324 — Carina Nebula – NGC 3372, NGC3293 and NGC 3324

Object name: NGC 3372, NGC3293 and NGC 3324
Object type: Emission nebula, open clusters
Location: Bogotá, Colombia.
Date: March-2013
Media: Graphite pencil on white paper. Scanned, inverted and processed with photoshop.
Equipment: Celestron skymaster 15X70 Binoculars

Hello all,

I don`t really remember which day of March I started doing this sketch, but the day I started it, the moon was high in the sky so I postponed the sketch to catch the most number of stars possible in this vaste region of the sky. However, I had to postpone the sketch for forever due to the cloudy weather and finally I decided to proceed with the information I had.

I started this sketch with no information about the deep sky objects I was watching. I saw a column very rich with stars, most of them unresolved with the binoculars and forming a vaste region denser and whiter than the LP background sky. I also noticed two groups of stars close to the column (NGC 3372): NGC3293 and NGC 3324. The best out of the three was without doubt NGC3293: just 7 stars could be resolved well, but the whole cluster seemed to shimmer and glow.

This region seems to be a hard one to sketch, but I would like try to sketch it again from a less light polluted site.

Thanks to all for watching.

NGC 6337 Revisited

Hello again! This time i sketched NGC 6337 from the rural skies of Doyle (160km away) at a star party. Luckily the central asterism (http://www.capella-observatory.com/images/PNs/NGC6337Small.jpg) appeared so much better and no filter was needed for the nebula. I used also a bunch of different eyepieces for the challenge.

Object Name: NGC 6337.
Object Type: Planetary Nebula. Apparent mag. ~12.3.
Location: Doyle, Buenos Aires Argentina.
Date: 12/05/2013 3:00-4:00 AM.
Media: Digital tools. PS 5.

Telescope: Dobson 12″ F/5.

Eyepieces: ES 11mm 82º, BST Explorer 8mm/5mm, TMB II Planetary 5mm/4mm.

Filter: No filter needed (yay!).

Bortle Scale: 3, Rural Sky. Very good transparency, average seeing.

Thank you again!!

Alnitak Nebula Complex

Hi,

In attachment you can find sketch of nebulas complex in Orion around
Alnitak – NGC 2024 (Flame Nebula), IC434 and B33 (Horsehead Nebula),
IC435, NGC 2023

Short description:

Object Name NGC 2024 (Flame Nebula), IC434 and B33
(Horsehead Nebula), IC435, NGC 2023
Object Type emission nebulas and dark nebula (Barnard 33)
Location Budy Dłutowskie – small village in central Poland
Date 04.03.2013
Media graphite pencil, white paper, color invert
Telescope Columbus 320UL (320/1384 Newtonian) +
Orion Q70 26mm + TS H-Beta 2”’
Seeing 2/5 (good)
Transparency 2/5 (good)
NELM 5,5 mag

I’ve heard that is possible to observe B33 under medium sky
condtitions (5-6mag) using 12” or bigger scope and H-Beta filter and
I’ve wondered is it true… In 2012 I bought 2” TS B-Beta filter and
after some months of really bad weather in Poland I tried it three
days ago.

When you looking thru the eyepiece you can see Alnitak and misty
shadow of flame nebula. All views using H-beta filter are really dark
so you need few minutes for eye adaptation and you need also to cut
off from all external light sources (using some towel on head or
something like that 🙂 ).
After this adaptation really faint fog of IC434 will appear and in the
middle you can observe small black roundy shaped place in this nebula
– this is the shape of B33.
You won’t observe horsehead shape in 12-16” telescope probably even
in extremely good sky conditions. To see horeheadshape you need 18”
or bigger scope and H-Beta filter.

But its worth to try to observe it. It’s a challenge which can give
you knowledge how you can “detect” and observe really faint objects.

McNeil’s Nebula

Friends:

Here is my submission, which is, I think, not only my best sketch to date, but also my most valuable one: as I cannot find any other one of the nebula during its short 2008 outburst.

* Object Name (McNeil’s Nebula)
* Object Type (Likely emission nebulosity, outburst of V1647 Ori)
* Location (Santa Cruz mountains, north of Santa Cruz, California)
* Date (12-20-08)
* Media (graphite pencil, white black paper)

The sketch was made in my logbook after a long study about the the nebula, careful preparation of regional charts, and intense scrutiny during a session arranged just for this observation, using my Orion XT-10 Sky Quest 10 inch Dobsonian (f/4.7, 5 mm Orion Stratus eyepiece [240x, 1.1 mm exit pupil, ~17′ FOV], without filtration.)

Sue French, “Deep Sky Wonders” columnist for “Sky & Telescope” magazine, had carefully observed the previous outburst of McNeil’s nebula in 2004, with a 10″ Newtonian (confirmed by Joe Bergeron.) She studied my report and first and second drawings, and commented in reply, “You no doubt saw McNeil’s reflection nebula.”

My lengthy article about the nebula, and this observation, is found at:
http://freescruz.com/~4cygni/astro-app/essays/fuzzy-objects09.htm#McNeil

This article discusses the meteorological conditions, and many other aspects of my quest to see it, and the actual experience, plus my background research. The viewing location was a rural private road in the Santa Cruz mountains, south of San Jose and north of Santa Cruz, at an elevation of 3,400 feet (site of some previous Don Machholz comet discoveries.) The drawing shown was confirmed by me with a second sighting and sketch made with a C-11 telescope, at Lake San Antonio further south, on 12-28-08.

Frosty Leo

Object name: Frosty Leo (IRAS 09371+1212)
Object type: protoplanetary nebula
Location: Nádasdladány, Hungary
Date: 2013.03.07 21:15 UT
Media: B + 5B pencils on white paper, inverted digitally
Telescope: 12″ f/5 Newtonian on Dobsonian mount
Magnification: 469x
Seeing, transparency, SQM: 5/1, 3/5, 21.16 MPSAS
Temperature: 280 K

Description:
A rarely observed protoplanetary nebula I’ve first read about in Cloudy Night’s Sketching forum. It’s as small as expected, but much fainter. Elongated to the N-S, with a clearly visible dark band divinding the nebula to to halves, when the seeing gets better for a few moments. Reminds me of a faint little nearly edge-on galaxy. I haven’t checked photos of this object before my observation, so I’m quite surprised now that I’ve seen the dark band, because even on a sketch made with 600mm scope it does not show up. But I know that my eye did not lie. A highly recommended gem.

Located in a rich star field in Scorpius, i tried to see the central asterism of the nebula but i couldn’t (only the brightest star). Link of the asterism here: http://www.capella-observatory.com/images/PNs/NGC6337.jpg. I’ll try again in rural skies.

Telescope: Dobson 12″ F/5.

Eyepiece: SP 6.3-10 mm.

Thank you and best regards.
