NGC 6520 and Barnard 86

NGC 6520 and Barnard 86
NGC 6520 and Barnard 86 (B86)

Location: Nagyvarsány/Hungary
Observer: Viktor Cseh
Date: 2012-06-17
Telescope: 140/880 Newtonian reflector + 10mm ocular

Coordinates of the NGC6520: 18h03m -27°51′

This is my favourite open cluster! Small but bright, and very unique. The dark nebula can be seen very definitely, triangular, and there is a small tongue. The lights of Milky Way in the background.

Clear skies!

Misty Star in Monoceros

NGC 2261 - Hubble's Variable Nebula
NGC 2261 - Hubble's Variable Nebula

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.

Delicate but Detailed Curtains in Orion

Emission Nebula in Orion
Maui, Hawaii elevation 4000 ft
27mm Panoptic, 56x

Graphite pencil and white paper, inverted using PhotoScape

I have observed this amazing region many times & each time try to tease out a little more information. On my last observation I could see folds like a curtain in a portion of the nebula, delicate but detailed.

Hi,

In attachment you can find sketch of emission nebulous complex known as Rosette Nebula (Caldwell 49)

Short description:

Object Name: Caldwell 49 – Rosette Nebula
Object Type: emission 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” + Lumicon UHC + Orion Q70 26mm
Seeing: 3/5 (average)
Transparency: 4/5 (weak)
Outside temperature -21*C !!!
NELM: 5,8 mag

Another sketch made in extreme temperature (-21*C) 🙂
This time object which you can find on many photos but which is not so popular in visual observations – Rosette Nebula in Monoceros.
It is quite easy to observe with some UHC filter (Lumicon, Ultrablock) and wide-field eyepiece (1,3* FOV is necessary) even in 6” telescope.
In 10” or larger mirror you can try to find some faint nebulosity regions with some dust pillars and lighter gas areas (but really good transparency is necessary).

Several Days with the Orion Nebula

Messier 42 and 43
Messier 42 and 43

Hi all!

That was the longest observation, in my life. I drew the Orion nebula for several days (total length of over 5 hours).
2012-03-18 Day 1. – the brightest stars are sketched (50 minutes)
2012-03-19 Day 2. – The faint stars drew a picture (up to magnitude 13) (90 minutes)
2012-03-20 Day 3. – I drew in high mist details dark and clear sky. (90 minutes)
2012-03-21 Day 4. – worked in the drawing (approximately 120 minutes)

Location: Nagyvarsány/Hungary
Observer: Viktor Cseh
Telescope: 140/880 Newtonian telescope, 35X, 88X, 176X

Clear Skies! 🙂

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
