on 15th August, I decided to make a lunar crater drawing. It was the first in 2013. I was even a little scared and realized when making the drawing, that it was not so easy on the hand. The edge areas also act somewhat coarser than usual, but overall I was pleased with the “Parry”. I noticed this crater is, as it almost appeared hexagonal or honeycomb.
The air was in the low-lying moon of course not the best.

Hello artists
Just a few hours after the great sketch of Stratos Tsanaktsidis, I had the opportunity to draw this one. I use a common H alpha PST Coronado.
My technique is quite original, after a light circle portion made by a graphite pencil on white paper I use directly a pure watercolour “green emerald” to sketch the solar surface on a water base and then the protuberances on the dry part of the sky, taking into account that light green will become dark red and vice-versa. Then I just have to invert the colours after scanning. The white sky is becoming black while the green part is becoming “H alpha red”.
Right, I add the approximate dimension of the earth and the moon orbit.
Object Name: Jupiter
Object Type: Planet
Location: Lombard, IL, USA, 41° 52′ 48″ N / 88° 0′ 28″ W
Date: 13 Mar 2012, 20:15 CDT
Media: Pencil
Comments: Attached is the glorious Jupiter, with its four Galilean moons, from left to right: Io, Europa, Callisto, Ganymede. Usually, Jupiter shows more details, but its way past its prime viewing conditions at Sun-Earth opposition. The sketch was done by pencil, as observed at 240x, sky around the planet turned negative after scanning. Jupiter colors were adjusted using Photoshop to resemble observable Jovian palette better.
I’m re-sending this email with appropriate subject,

In this year’s my vacation, I stayed an observatory.
The sky was not clear, so I drunk until dawn with my friends.
AM 4:00, I lay visitor’s room, and I saw cloudy moonlight outside of the window.
It was very fantastic! I drew a picture using my smart phone immediately.

The sun’s activity is very important in this moment, causing greats eruptions that I drew the best I could. Note that few sunspots appear (maximum 2). The dark lines on the sun are eruptions pointing in our direction.
this is my sketch of NGC 7331, the Deer Lick Group.
Drawn on 5.9.2013 at hohloh, kaltenbronn, black forest, germany.
Telescope used: 18″ at
135x for details in NGC 7331
400x for its companion galaxies.
Drawn with graphite on white paper (using tortillons, erasers)
scanned, inverted, and processed to remove “dust-stars” from scanning, darkened, and used the smudge tool
in PhotoFiltre to soften the Galaxies.
Hi, I send my sketch of Saturn. The Saturn is my favorite of the planets. I live in Psary in Poland. The sketch I did on the night of 30 April to 01 May. I had a very good view of the scale of 8/10. Saturn showed a lot of detail. You could see the famous Cassini gap. The atmosphere was very calm and did not cause degradation of the image of this interesting planet.
I was using 200x magnification. My telescope is a Newton 200/1200. I used a pencil to sketch 2B and white paper. Using GIMP I added a black background, which gives a realistic picture of Saturn with a telescope. GREETS 🙂

I’ve really been enjoying the current set of active regions the past few days. It would be nice to sketch each individual active region as a close up view, but to do that would take several hours. As it was today, I struggled with a group of thick clouds for the first hour of my session. The sky was crystal clear when I set up and I chose to ignore the weather channel for my area stating that we could have thunderstorms at 8 a.m. Thankfully the storms never came…the clouds did. I was able to catch glimpses of the Sun in between the clouds and by 8:45 a.m., the sky was nearly unobstructed.
The first features added to the sketch after the prominences were plage from 1476 and 1471. Next came the sunspots themselves and filamentary structure. By 9:10 a.m. (1410 UT), very bright plage appeared just north of the sunspots in 1471. I haven’t been able to confirm yet if it was a solar flare, having expected possible flare activity in 1476 instead. But it lasted nearly an hour before it dulled somewhat. Near the end of my session, 1471’s plage brightened quite a bit to the eastern side of the major sunspot in that region as well as about five more degrees further east again.
1474 and 1475 paled in comparison to the two major active regions. There were nice filaments and thin plage that made them easy to find.
The large chain of filament reaching to the southern limb was still there, although thinner. Prominences scattered around the limb were insignificant.
