Hi Mike,

indeed this is an impressive sketch - I agree with Ruud!

And thanks for the background information!

Clear skies!

Hello Mike, Hello Andrew,

thanks for your great feedback!

@Mike: I have adjusted the white balance. Now it should be more a black sun. I mean it will end up in black carbon some day

But so far: Clear and sunny skies!

Hi all,

thanks a lot for the feedback!

Tonight  I  looked up the craters and secondaries in my "Atlas and Gazetteer of the near side of the moon" and was able to identify most of them.

Hi Ruud,

that's really a great sketch of a larger lunar area! Thanks for taking us with you to the moon!

Dear all,

at the end of a sunny day I set up my largest telescope, the 10" f/5 truss-tube Dobsonian Martini to do a tiny chalk/charcoal sketch. I wandered the terminator up and down to select a target. Clavius and Tycho were already too bright, Aristarchus and Herodotus were still in the dark and once again a Gassendi sketch, I wasn't too keen on. I ended up pretty much at the southern limb and selected the area of Klaproth and Casatus:

Dear all,

yesterday evening after doing the sketch of the three-day old moon, we had a wonderful twilight scene with Venus and the Moon over here.

So I did a pastel sketch how I recalled it afterwards:

Clear skies!

Hello Mark,

that's a wonderful naked-eye sketch of this well-known astronomical target. Well done!

Clear skies!

Dear all,

during these odd and hard days on our planet just staying home, I enjoyed having a look at the three-day old moon just for clearing the mind a bit. I spend relaxing forty minutes doing the sketch. Here it is:

Hello Mike,

great sketches - I like especially the sketch of Petavius!

Clear skies

Achim

Hi,

an excellent idea to show and locate the sketches!

I went for a different approach - a bit more unsorted

Clear skies

Achim

Hi,

that's a fine sketch. Your technique of shading and then erasing produces impressive results!

Clear skies!

Achim

Hello Mike,

thanks for sharing both the old and the new sketch with us here. Both are great!

Clear skies!

Achim

Hi,

for two reasons: The granular effect is one thing, the other is that the pastel sticks better.

Please can I use it to show to my GCSE Astronomy pupils as an example of what is possible when I ask them to make a sketch of the Moon? Some of their attempts so far have a long way to go!

Hi,

yes, of course! Feel free to do so!

Clear skies!
