For the others who were interested in more detail about the Keyhole Nebula pic on Tuesdays broadcast, AAO answered some q's on twitter today so I asked them about more details and AO :
"The focal length of the @AAOastro AAT is 12.7 m. Its primary mirror has a size of 3.9m. This gives F3.2 at primary focus #AskAAO "
and
"We don't have AO (adaptive optics) at the @AAOastro AAT (but working on it). CACTI provides a field of view of 7.85' x 7.85' #AskAAO"

Hi Dylan,
OK so no adaptive optics - thanks.
cheers
