Lunar crater Tycho unfinished
Sketch and Details by Frank McCabe
I was about 45 minutes into this sketch when I began thinking about the last time I started a close up sketch of the crater Tycho. I was stopped shortly into that attempt by fast approaching clouds. This time I was not concerned because satellite images and the Clear Sky Clock for my area revealed little or no chance of that and suddenly as if on command the clouds rolled in from the east and sketching was over.
So I share with you my second attempt at a Tycho crater sketch. What is it they say about the third time?

Great partial sketch, Frank! It’s nice to see your process in the areas that are incomplete. It’s funny how deteriorating conditions can really pump adrenaline into such a sedentary activity.
