Sunset Over Four Big Craters

“Sunset Over Four Big Craters”
Sketch and Details by Giorgio Bonacorsi

Hi astronomy sketchers,

I sent this Moon sketch, made behind my home with a Kenko 80/1000 refractor.The night was partially clear, only some clouds cover the sky .The Moon was splendid, the phase is two days after Full. I see in my telescope and i am surprised:Turbulence and wind compromised a perfect image.I made only that portion of Moon, a very difficult drawing. The vision is splendid:Petavius and other big craters,Langrenus,Vendelinus and Furnerius going in the shadow.

Thank you for all,
at next sketches.
Clear sky,
Giorgio Bonacorsi from Italy.
