    I swear I'm not trying to criticize, but, uh--why only 10 or so photos? Why not just film it long term? Is it our position in earth's orbit that only lets us image that system once a year or so?

      Telescope time is precious.

        I would also assume it's not just "okay hit the button, okay there's that snapshot", it's likely sitting there collecting photons for a _while_ to get each picture.

          Yeah each photo is one - five nights of work full time from 3-5 people.
