The Observatory's gallery features more camera technical info than the BBC article.
This webpage states, "See over 100 images from the past 10 years of the competition in our greatest exhibition to date." with a "visit the
exhibition" button, but a click on the link required a password which I presume means that you have to be a dues paying member of the Observatory (OR
it may mean that it's 'off limits' for a USA visitor).
