Finally got out to have a go at Clavius.
I started early before sunset even. As it gradually got dark I could see more details coming out. Didn't really get the overall shape right with this one so not particularly happy with it.
So went back for more. This time I had to contest with the clouds starting to come in. As a result did not get quite as much detail on the page but the overall shape is better.
I think I completely under estimated the complexity of this beast when I picked it.
