Hi
Because of the lot of people who would like to go to the Hartebeesthoek Radio Astronomy Observatory, we hit the limit of the people who would like to go (28 definitely) and the amount of people in a single group that they can accommodate (max 35 people).
We have two options, everyone books on their own for the 4th of June, and we all just pitch up and hope we don't hit the 50 person limit along with the other people.
The other option is we arrange a private visit, which involves a separate date and the payment of a deposit. It is logistically more of a mission, but might be worth it.
To make a decision, I set up a poll on Google Moderator here:
http://goo.gl/mod/TSmmPlease vote which option you think is best, and if you choose the second option, which date you would prefer. The 11th of June the moon will be full, so will limit the objects we can observe (the observatory provides telescopes that you can look through), the 18th is just after the public holiday so it might not be a option for people going away.
