Today I present two crescents of the two clear nights (12.04-2013 and 15.04-2013). Although … some people think that these sketches are a little … ghostly … 😉
Yours Robert
Sketch details:
Object Name: Two crescents
Object Type: Moon.
Location: Poland, Oborniki

Equipment: Newtonian telescope 409/1800 (Capella 41), and 22 mm eyepieces
Object: ? Artist: Robert Twarogal (Ignisdei)
Object Name: Saturn
Object Type: Planet
Location: Maastricht – Netherlands
Date: April 23th, 2013 – 22.30h UTC & May 5th, 2013 21.30h
Media: Graphite pencil 5B on white paper
Seeing: Bad
Equipment: 12″/F5 Dobson – Nagler 3-6mm Zoom – 300x
I made this sketch of Saturn from my backyard on April 23th, but left it lying around far too long to finish drawing it from memory. So tonight I took the opportunity to do some more observation and complete the sketch. Seeing was bad as Saturn hovered low above Maastricht city. The moon probably is Tethys.
Object Name: Grimaldi, Hevelius, Cavalerius
Object Type: Lunar craters
Location: Twello, The Netherlands
Date: April 23, 2013
Media: White pastel pencil on black paper
It has been more than a year(!) since my last lunar sketch, but on the evening of April 23th I dragged my 3″ f/16 Polarex refractor outside for some good old sketching.
The most prominent feature on the lunar surface was a line of large craters formed by Grimaldi , Hevelius and Cavalerius. Although the Moon didn’t climb higher than 30 degrees above the Southern horizon, magnifications up to 200x could easily be used. High cirrus clouds made the image a bit hazy (and I had to stop sketching after an hour because of thickening clouds) but the seeing was quite good. The sketch was made through an old 7mm Orthoscopic eyepiece (171x). The image is mirror reversed (north=up, west=left).
Another from the early hours of morning, Arp 254 a lot going on here beyond my sketch, but knowing of the interaction taking place and seeing the start of the bridge is quite an amazing thing if you think about it!
I have a little back log of sketches that I need to get out to you, I just did this one as it was a single and I wrote the blog pretty quickly!
I submit to you my sketch of planetary nebula NGC 6818 and the beautiful open cluster of stars that frame it, NGC 2818A, in the southern constellation Pyxis. The night was exceptionally clear & still at ~10,000 foot elevation site of Haleakala.
At the eyepiece this planetary appears as a greyish, elongate & irregular ghostly object within a lovely, but dim open cluster of 10th to 14th magnitude stars. On prolonged observation this open cluster takes on the appearance of petals of a flower with the planetary somewhat offset in the central region. The planetary nebula is best seen with averted vision and a narrow pass band filter which is helpful to better define the borders.
Though NGC 2818 & its often cited as a member of this open cluster of stars, accurate measurement of their velocities suggest this is a only chance alignment. http://apod.nasa.gov/apod/ap090122.html

Object Name M97 and M108
Object Type Galaxy and Planetary Nebula
Location Banyoles (Girona), Catalonia

My equipment is a Dobson 10″ with a 25mm eyepiece. The seeing and transparency is 7/10.
Sorry for my english, this is my first sketch with my new dobson. When sketching that you see, you see more details!! It’s awesome!
The name of the sketch, “The Tango” is from… this objects are very spectecular pair on the sky, and give me a “Tango” idea.
M 51 in interaction with its companion (NGC 5195) is one of the most beautiful images that gives us the sky for amateur astronomers. In a moderately good sky and with a half-open tube appreciate how the disks of these galaxies are playing.
Two spiral galaxies are located in the northern constellation of Canes Venatice, about 3 ° away from the star Alkaid (eta UMa). Its location is easy as can be distinguished in the search box 9x as a tiny gray haze. With letters from mag. 6.5 takes me a couple minutes to find them.
Also called the Whirlpool Galaxy, M 51 is a very bright object with a bright nucleus, where it descends gradually to the outside light to get lost in a blur round irregular contour. The brightness of the disk is irregular with signs of spiral arms.
It’s pretty big, about 8 ‘, in relation to the eyepiece of actual field 1, and its shape is round, somewhat flattened perhaps because we see her face.
Attached to the contour Visibly M 51 NGC 5195 is another spiral galaxy about 2 ‘in size, round and rather less luminous than its companion.
Another feature that is seen in M 51 is a little star superimposed in the middle of your disk.
Scattered throughout the field there are several bright stars and about 15 ‘of the galaxy, the more brightness of all.
The 80x I get the best view and choose to do the part. Also alternate direct vision and diverted.
Object name: NGC 3372, NGC3293 and NGC 3324
Object type: Emission nebula, open clusters
Location: Bogotá, Colombia.
Date: March-2013

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.
