TMT — A stargazer’s personal view

When I moved here, Canada-France-Hawaii Telescope (CFHT) was the biggest telescope on the mountain. At a smaller NASA observatory, I watched my astronomer friends Bill Hartmann and Eleanor Helin as they observed planets and searched for asteroids (“Glo” Helin later named one of her discovered asteroids after me!). I myself observed supernova 1987A through a small telescope on another trip to the summit.
