Yesterday I participated on a small experiment from my local astroclub: counting migrating birds that passes the moon. The observing condition was terrible: a lot of high clouds. The only objects I could see with the naked eye were the moon, Capella and Vega (Jupiter was behind the house of the neighbours). This makes a NELM of 0! But good enough to see the moon and the birds. I counted 4 birds in 30 minutes.
Because counting birds is not really thrilling... I searched for a nice region to sketch. The craters NW of Montes Jura looked good to me. Because there were a lot of clouds, there weren't many details visible. But this made the scene more easily to sketch!
Some weeks ago I posted my first sketches of the moon, made with a 7x50 binocular. I learned from the comments: take a smaler region, try higher magnification and draw on a bigger piece of paper. Thanks again everyone for these ideas.
I'm used to sketching deepsky. What kind of information is important for lunar sketching? I hope you like the labeling... I do. It makes the sketch more impressive to me. All comments are welcome.

30/10/2009, 22.00 UT, 7cm refractor (Meade ETX-70), magnification x87, NELM 0, moon 90%, white pencil on black paper, scanned and mirrored.

Jef,

You have an eye for the craters in the mountains through the clouds. That was a great idea to double task.
Very nice sketch of the moon. :bow: :rainbow:

Frank :)

Jef,

I enjoy the shadowing of your craters and I agree, I really like the labeling and that you kept it from interfering with the sketch. I might have labeled them 1 2 3 etc or A B C and then put a key off to the side. Not sure if that would be as effective though.

Everery observation is better than a non-observation. An you mastered the atmospherical conditions quite well! Keep sketching.

Very nice field sketch :bow: :bow: :bow: and the labeling enhances it. Something I rarely do but need to focus closer on certain regions and add some labeling eventually. I like the sweeping perspective you rendered here and the darker grey tones as if through clouds; just the way we observed it tonight here in Oregon through broken clouds.

I cannot help but agree with Uwe; everyone needs to observe more often as any observing at all is good. God knows I have missed some great moments over the years, making excuses as I could have been out observing and at least doing some rough field sketching instead. I am locked into a mode of doing only a huge work of art and this commits me to procrastinate at times.

As I retuned home tonight after allowing a few dozen people to see the moon through a Nexstar 5i Cassegrain, I wanted to sketch even though the moon was in and out of clouds all night but the public usually comes first when I do this. Now I am waiting again for clearing.

Thanks for posting your sketch, as you have inspired me to persevere.

Mark

Nice moonsketch Jef, the shadowing is really good imo, not easy. about the labeling, i might have put a key to the side as well as jay said. but that's just personal opinion.
we're having a few pretty miserable cloudy weeks over here. it drives me crazy, the few times i've set up the scope last month, either the seeing was horrible or by the time i got out to observe mars, clouds had rolled in again... nice to see you got to make a sketch :waytogo:

Everybody, thanks for the kind words.
Uwe and Mark, I agree we don't profit 100% from the nightsky. I know people who only get out when there's no Moon. They see our satellite as "lightpollution" :shrug:
Jay and Kris, I'll try the other labeling technique next time. The lettering is a "standard setting" in Corel Paint, but it was just what I needed.
Kris, it isn't getting any better in Belgium... The rain is pooring down for the moment :bawling:

Jef,

An excellent observation of the Sinus Iridum and craters surrounding the is lunar bay. Thank you for sharing them with us all.

Carlos
