Electronic Astronomy My article appears in "Exploring Space," the Spring issue of the Exploratorium Magazine. I visit astronomer Mike Bolte at the Canada-France-Hawaii Telescope on Mauna Kea and end up getting the visit of a lifetime. I ride to the top of the telescope to add liquid nitrogen to the CCD! Then observing on a night with fantastic seeing. |
