By the way, while I love to help people discover #books they’ll find interesting and enjoy reading, for which purpose I created and maintain a now well-established website, I earn my daily bread and cheese developing #binoculars, #spottingscopes, and #microscopes for Celestron. So if anyone ever has any questions about those types of optical instruments, including the history of them, I’d be delighted to help answer them. #birdwatching #birding #nature
