Great shot! some of the finest details I've seen from a UK image for a while, focus must have been absolutely nailed 

 Actually can't remember the last image I saw which capture the rille for almost it's full length through the valley

Very nice capture of this feature.

[Craney]

Wow !!   you must be getting down to sub-100m resolution with that shot.....

Nice one Paul. Was looking at this region the other night but could not see the rille.

[Ben the Ignorant]

Impressive for an f/20 shot given that you could go f/40 if the air doesn't tremble.

Great photo Paul. I tried to see the rille last night with the 12" Dob but failed.

That's a terrific image, and superb detail for such a close up shot, thanks for posting.
