re: A little more...
To me this is really fascinating and amazing technology. I'm sure Galileo would've been delighted with how his invention continues to evolve. The continuous innovation of telescopic technology also shows how incredibly complex systems emerge from stepwise improvements. Interferometry, segmented mirrors, adaptive optics, and laser guide stars...its all amazing and seemingly will keep ground based astronomy improving for years. BTW, love the pictures. Keep the post cards coming.
