Conjunction over an Italian town skyline

Conjunction of Venus and Jupiter - August 18, 2014

Conjunction of Venus and Jupiter – August 18, 2014

Object Name- Venus, Jupiter
Object Type Conjunction of planets
Location Pesaro, Italy
Date 18th August 2014

I woke up early at 5:00 o’clock to take a look at this marvelous conjunction. It was still night at the time and I was surprised with a mighty view of the rising Orion. I waited on my balcony for until the planets were visible over the roofs in front me. I quickly took my pencil and drew what I saw on the eyepiece of telescope, but the seeing was awful and just two moons were visible. The view of this two small lights dancing together over the roof in the cold morning was much more intriguing, so I tried to sketch the whole landscape. Never tried this kind of astronomy sketch before, probably my first landscape since I was a child.

Messier 17 – The Swan Nebula

This is my sketch of the Swan Nebula, NGC6618. It was sketched through a Meade Research Grade 12.5″ F/6, using a Celestron UHC filter and a Nagler 16mm Type 2.. La Verne, CA is located in a Red Zone. Thanks for looking!

Messier 57, The Ring Nebula

Messier 57, The Ring Nebula

Messier 57, The Ring Nebula

Object Name – Messier 57, The Ring Nebula
Object Type – Planetary Nebula
Location – Tullamore, Co. Offaly, Ireland
Date – 06 August 2014
Media – Graphite pencil on white paper (Image inverted)

This is my first sketch of M57. Observations were made using an Orion XT10i and a 17mm Wide Angle (65° FOV) lens.

The seeing conditions were average, however i made the sketch from my back garden under light polluted skies. There was also a half moon present which added to the skyglow.

I used averted vision to notice the subtle features of the slightly elongated nebula. The central star was not seen in my telescope.
Observations were made with and without a DMC Narrow Band Pass Nebula filter. The filter slightly increased the contrast of the nebula while obscuring the background stars.
Overall I am very happy with how it came out.

NGC 1999 - A reflection nebula in Orion

NGC 1999 – A reflection nebula in Orion

I would like to show, through this drawing, how the seeing is important to observe and describe very little objects.

Object: NGC 1999
Object type: reflection nebula and globule
Constellation: Ori
Date of observation: 2011 10 01
Length of observation: 60 min
Height of object above horizon: 28.5°
Observing site: Observatoire des Baronnies Provençales (Southern French Alps)
Observing conditions; exceptionally good, mag limit 6.7v, SQM 21.50, FWMH 0.9” !!!
Instrument: Dobson Obsession 25”
Eypiece: Ethos 6mm, without filter, power 520x

Notes: I am astonished: at the eyepiece, I have in front of me a delta winged aircraft, perfectly clean. Extremities of wings are curved, the “head” of the craft easely detailleable. The encreasing of bright nebulosities around the head and at the back of the wings have also been noticed.
The caracteristic blue color of reflection nebulae is obvious.

Much more details can be found at www.deepsky-drawings.com

Lunar crater Mersenius - August 7, 2014

Lunar crater Mersenius – August 7, 2014

Hello,

After some weeks during the “White nights” without a look in the sky, I started observation at the 7th August with my new 130/1200 Aspherical Doublet Apochromat (it was planned by Ralf Mündlein and me in the last two years) the planet. The air was quite well and the conditions were warm and dry.

A nice crater with some little impacts and mountains at the bottom took my attention. So I made a drawing of this view. I hope you like the “Mersenius”.with it´s nice landscape.

Planet Saturn - July 25, 2014

Planet Saturn – July 25, 2014

- Object name: Saturn
- Object type: planet
- Location: Tarján, Hungary
- Date: 25.7.2014., 19:21-19:37 UT
- Media: sketch with graphite pencil, finished with a drawing software

After weeks of cloudy weather I was finally able to make a sketch about this beatiful planet.
The drawing and the writing of my notes took approximately 15 minutes. The skies transparency was quite good, but the air conditions were bad, so I had to wait long to see some details. I used a 102/1000 Celestron OmniXLT refractor and 170x magnification during the observation.
After the sketch was done I watched some other object on the sky, so I finished my draw at home, using my laptop.
I hope you like it.

Light vs Dark – the Ink Spot and a lovely open cluster

Tue, 08/05/2014 - 03:00
The Ink Spot, B86 & NGC 6570

The Ink Spot, B86 & NGC 6570

Hi all,

This was the first sketch I completed at Astrofest in Queensland, Australia. I’ve been wanting to sketch this beautiful dark nebula ever since I first laid eye on it some three years ago. This dark nebula, B86, goes by the popular name of “The Ink Spot”. It sits smack bang in the centre of the densest star cloud in the whole sky, the Cloud of Sagittarius. And what sets it off even more is B86 has a gorgeous bright open cluster right next to it, NGC 6570. Both objects are more-or-less the same size as each other, even though both are not very large themselves. But it is the juxtaposition of these two very different objects against the blaze of the Milky Way that makes this pair a spectacular pairing.

Dark nebulae are clouds of dust and gas that are drifting through the Milky Way galaxy. Many of these conglomerations of dust and gas do end up being formed into stars and planets, but most just end up forming the fabric of the galaxy. In fact, the stars that we see actually only form a small percentage of the actual mass of galaxies. By far the greatest amount of a galaxy’s mass comes from this very dust and gas. The Ink Spot is a small patch of cloud. It is a very opaque nebula too. Dark nebulae are categorised according to their opacity, or how dark they are. The scale of opacity goes from 1 (very tenuous) through to 6 (very opaque). While the opacity of The Ink Spot may be a 5, it is because that it sits in the Cloud of Sagittarius that makes is a striking object.

The little open cluster NGC 6520 really works very well in setting off B86. Open clusters are groupings of stars that are all related to each other having been formed out of the same parent cloud of gas and dust. Evidence for this is seen in the spectra of the stars displaying the same chemical make up. The brothers and sisters of our own Sun have been identified this way, with the same chemical signature as our Sun having been identified in several close by stars even though the Sun’s ‘siblings’ have long drifted off away from each other. Open clusters are loose groupings, so even though they formed from the same source, their gravitational connection to each other is not strong enough to keep the group together for too long.

For me, this tiny patch of sky is one of my most favourite. Tiny and oh so precious. Brilliant, dark, stark, ghostly. All in one. Gorgeous.

Alexander Massey.

NGC 6309, “The Box Nebula” and per Stephen J. O’Meara in his book “The secret Deep”: The Exclamation Mark.

NGC6309 – Exclamation Mark Nebula

NGC6309 is one of the two planetary nebula with the nickname “The Box”, (the other is NGC6445 in Sagittarius), but after my experience with it, I prefer name NGC6309 like Stephen J. O’Meara in his book “The secret Deep”: The Exclamation Mark.

Spring’s Trio, “The Leo Triplet”, galaxies M65, M66 and NGC 3628

It is spring’s trio.

The dark lane in the 3628 is really fantastic!

Before this sketch, I always confused M65 and M66.
But now I can classify 65 & 66.
Sketch is magical tool in the visual astronomy. :-)
