My example was the 2010 Queensland Astrofest. The event extends over 10 days and I don't think anyone expected 75mm in one day/night
, but even 10mm can seriously fill the covers if they don't have some sort of centre support.
I am considering using a tent like this for a dark sky site, until I have the means to erect a more permanent observatory... the dew sometimes get pretty heavy, let alone any shower activity.
$2k is out of my league, but $800 might get it over the line as a portable observatory, cover, and "warm room/control room". And all insect free for when the weather is more pleasant, but the bites aren't
