This night I sketched a bunch of ghost craters. The largest one is Fra Mauro, surrounded by Bonpland an Parry M. Palisa and Tolansky are also in the sketch but they are no ghost craters.

 

After I while I sketched again with graphite pencils. It is easier with them to reproduce delicate detail, but it is not as easy to reproduce the illusion of light and shadow.

Nice sketch, Uwe. Reminds me of the downside of the mild weather we currently have here: perpetually cloudy skies.

 

Hope it clears soon; I want to see this month's Moon too.

Dear Uwe,

you were lucky to have a clear sight to the moon.
And you've used the opportunity for this great sketch. Well done!

Clear skies!

Fabulous sketch, Uwe!

But forgive me for asking.  

Did you not see Rimae Parry going through any of these shallow craters? 

I observed it on the 13th May 2019 with my William Optics apochromatic refractor at 225X going through Parry, Fra Mauro and Bonpland.  

Admittedly I did have excellent sky conditions. 

 

Not to worry if you didn't. 

Please keep your sketches coming, Uwe. 

 

Clear skies, 

 

Aubrey.

Uwe,

 

Very nice sketch of these craters. This is an interesting region of the Moon to capture. I have spent some enjoyable nights sketching in this region.

 

Frank :)

> Did you not see Rimae Parry

 

I did not see them. Please keep in mind that the sun stood high about that region and the rimae cast not a large shadow. Beside this, the air was rather unsteady. I worked with 100x and not, as usual, with 144x.

Thank you for your answer, Uwe. 

I always knew you were an honest man. 

Maybe you will get another opportunity to see and sketch Rimae Parry during 2020. 

It definitely is an enormously difficult feature to see. 

 

Kind regards, 

 

Aubrey.
