In this year of bright comets and while waiting for comet ISON, I will
mainly send sketches of these objects to show what can be seen in the coma!
Comet IKEYA – ZHANG was a bright and activ comet which showed interesting
structures in the coma. I observed before it was dark (twilight) to see the jets !
This comet is the same one as Hevelius observed in the year 1660.
Info on the sketch.
I used crayons (watercolor) on black paper.
Loc.: Trondheim, Norway.
Best wishes and clear sky from Per-Jonny Bremseth.

Title: a moon crater
My name: Silvia Fabi
Object name: /
Object type: crater
Location: Ferrara
Date: 13/04/2013
Media: 2B pencil and black marker in white paper
Seeing: III
Description: this is a very small crater near Petavius. I searched the name on an app of my phone and on a book but I didn’t find nothing. Anyway I think it is a intresting crater to sketch.
Hope you like it!

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

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

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
