Description

Hi All,

this image has been shot against all odds : half moon near to the framing area + some clouds (a lot really..) + almost half of the subs thrown due to auto-guide faillure (bloody clouds)...

By the way soon these subjects won't be visible for another year.... so i took my chance.

it's a pity because it was at least framed nice.

Clear skies
