The description of Boussingault and concentric Boussingault
A inside it sounds interesting, but I haven't observed this pair. Has
anyone else? Any interesting comments to share about this or other
features on these charts?
The southwestern end of Boussingault impinges on the interestingly named
crater Boguslawsky (bad legislation in Poland?). But the secondary crater
on the edge of Boguslawsky seemed to be at the opposite end from where Rukl
shows it.
I have a hard time navigating near the limb and especially when everything
is reversed as in an SCT. It took me 2 1/2 hours to figure out this little
bit. But it was a nice time :-)
