…and other large astronomy instruments. I watched a program about how technically challenging it can be to get large mirrors up to the most prestigious optical observatories, because they tend to be located in remote areas away from haze and light pollution and at high altitude in order to minimise atmospheric lensing distortions of the astronomical observations. The effort and precision required to first create a perfect mirror and then get it up an enormous mountain without it cracking/shattering along the way is hard to describe without wishing for a far less trite word than “impressive”.
I noticed that the high altitude observatories have pretty damn spectacular mountain outlooks, and some of the lower altitude non-optical instruments are intermittenly glorious as well. So I went a searching on Flickr, and created my first Flickr Gallery (a new feature): Observatories. I now have a few extra places I want to see that I’ve added to my bucket list.
