Deep-sky observation (my favourite open cluster)
DATE: 2011-10-18 18:22UT
Observatory: Nagyvarsány/Hungary
Observer: Cseh Viktor (Viktor)
Object: NGC 884-869 (in Perseus)
Telescope: 10X50 binoculars
Media: I prepared this digital picture with Photoshop CS2.
Clear skies!

M15 (GC in Pegasus)
Location : Kang-Won do, South Korea
Date : Sep/9/2011 (1hr)
Media : White paper, Sharp pencil (0.7mm, 0.5mm), Scan & Invert
Equipment : Discovery 15″ Dob, Nagler 9mm
I observed M15 under best sky condition.
Some star chains and star vacancy regions across the GC.
And finally I found Pease1. (Not visible in this sketch. Pease1 needs O3 filter)
Pease1 observation is very difficult.
So I use ‘Blinking Method’ with O3 filter..
If you want to see my Pease1 sketch, please refer to below link.

Thank You!
Hi all,
This October New Moon saw me attend for the first time the Ice In Space Astro Camp. The forecast threatened thunderstorms, but as luck would have it, the clouds parted to give us a great view of the sky. Thunderstorms did happen, but we only saw the glow of the flash of lightening from a massive storm system that lay behind a ridge.
My first sketch of the night was of 47 Tuc (NGC 104). This massive globular cluster is considered to be the remnant core of a galaxy long ago swallowed up by our Milky Way. There is at least one other remnant core, that being Omega Centauri.
The view of 47 Tuc through my 17.5” is nothing but astounding. At 125X the whole FOV is filled with countless stars. Its core is very compact and extremely bright, and the reach of the remaining ball of stars is impossible to determine its limits. Transparency was a little lacking, but you take what you get sometimes.
For once I added a FOV ring around the subject. My customary ringless sketch lacked a little something with this one as the field doesn’t extend to the edge of the page, the excessive blank black caused a lack of context. The FOV ring this time I feel gives that context to the sketch with only a small amount of extraneous stars lying just outside the ring.
An interesting comparison is between 47 Tuc and Omega Centauri, the two largest globular clusters in the sky. Omega’s core is larger in apparent size, while 47’s is much more compact and intense. This makes for an easier pick-up of ‘fingerprint’ patterns within Omega, while these patterns are much more subtle and even fickle in 47 Tuc. Still, these differences make for their distinct & unique qualities.
This was a challenge to sketch faithfully. As most of the stars in this cluster are actually quite faint on their own, it became more of a matter of attempting to lay down an impression of the collective features. The patchy ‘mini clusters’ around the perimeter, the suggested arcs and lines, and the distinct three ‘dark’ spots on the core, one of which is more of a bar that lies above two of the spots.
I hope you enjoy this sketch.

Object: 47 Tuc (NGC 104)
Scope: 17.5” f/4.5 push-pull dob
Gear: 16mm Unitron König, 125X
Location: Lostock, NSW, Oz
Date: 30th October 2011
Media: White pastel pencil and white gel pen on A4 size black paper
Duration: 1.5hrs.
Object: The Pleiades (M45) and the moon
Object type: Open cluster/moon
Location: Montreal, Canada
Date: December 8th, 2011
Media: White pastel on black paper, digital retouch
I marked the date in my agenda: The beautiful Pleiades and an almost full moon side by side. Something not to be missed. And the conditions were good: no clouds and a comfortable 3°C.
My 15 X 70 binoculars were the perfect instrument for this observation as the two objects could fit within two field of view. A sketch had to be done…

Hello,
Here is a m8 sketch I made this summer.
It was the first and last time I observed this nebula (because I observed it early and here, in Quebec, we don’t have good sky every day !).
I was alone with the radio in a blue-berry field, at Dolbeau. I remember… I saw Sagittarius constellation I and took my ipod to see which object I could see in this region… Nebulae and nebulae it had on my app ! I decided immediately to spot one of them with my 10 inch scope.
The Lagoon Nebulae
Without OIII, I easily saw the stellar cluster (NGC 6530) and I notice some nebulosity. But when I put the OIII filter… it was outstanding ! It first look like a cat footprint… My field of view did no allow me to see the entire nebulae. I wasn’t no anything about this nebulae this night and it was the main reason I drew it: When I came home and compare my sketch with picture I was just too happy 😛
Object Name: The Lagoon nebula, m8
Object Type: Emission nebulae with stellar cluster
Location: Dolbeau-Mistassini, Quebec, Canada
Date June 26-27 2011
Media: HB sketch pencil and shder brush
Instrument: Skywatcher 10 inch, 1200mm of focal length
Eyepiece: Celestron Ultima LX 13mm + Lumicon OIII filter

– Media: black pencil on with paper / PS CS5
The sky was pretty clear last week. There were two nights that I was able to observe the night sky from our backyard.
I made on the second night (22-10-’11) a few allround sketches from some of my favorite objects.
Here below you’ll see three sketches I have made:
M13: Globular Starcluster in Hercules. This object was very nice visible through the telescope (130/900) and the binoculars (10×50).
M45 in Taurus. A beautiful starformation that was very impressive through the binoculars.
Aldebaran & Hyads in Taurus: Also a very nice formation. These type of objects are best visible through widefield lenses or binoculars.
Thanks for watching!

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” 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.
