Robinson, editor of 'Sky and Telescope'. Robinson's career as an observer began with a series of planetary drawings and observations of the rapidly changing variable stars in the Orion Nebula. He worked at the Griffith Planetarium in Los Angeles before joining the staff of the magazine in 1962 as an editorial assistant, and he succeeded the late Joseph Ashbrook see planet (2157) as editor in 1980. Robinson has been an active promoter of professional-amateur cooperation in astronomy, and retains interests in solar-eclipse viewing and bird-watching. (M 16246)
If you choose Porro prism binoculars, you may also have a choice between center-focus and independent eyepiece focus. There are no advantages to center focus if the binoculars are to be used exclusively for astronomy, but if you intend to use them for terrestrial purposes (e.g., bird watching or horse racing) then you should get center focus. My preference for astronomy is independent focusing eyepieces. They tend to be more mechanically robust, do not suffer from a rocking bridge, and modern ones tend to be waterproof and nitrogen filled, reducing the likelihood of internal fogging.
