ASLI's Ed Anderson-"Understanding Eyepieces"

Now that you have purchased your telescope, what's next? The most likely accesories you will want to look into are eyepieces. These are the tools that provide the magnification that brings those distant objects closer for a better look. You may have gotten one or two with the telescope, but if you want to take advantage of its capability, you will need more eyepieces or a Barlow lens or both. However, like all aspects of the hobby eyepieces have a vocabulary of their own and a wide range of choices in price and features. Ed will try to make this complex topic understandable to beginners and may even have a tidbit or two for the more experienced. Ed Anderson is a member of the Astronomical Society of Long Island and the Custer Institute and Observatory. He is a frequent speaker and presenter at both organizations addressing the membership and the public. He has been featured in the newspaper Newsday and has published over 15 articles on several astronomy-focused websites. Ed is very active on the Cloudy Nights forums, under the screen name AEAJR, where he focuses his time on helping new people. He has a degree in business with a minor in physics. He recently retired from a 38-year outside sales career in data center technology, most recently for Hewlett-Packard Enterprise. Ed has been interested in science and astronomy most of his life. Ed entered into the astronomy hobby in a serious manner in 2015 and has been enjoying visual observing since. His current observing tools include binoculars and 5 telescopes ranging from an 80 mm refractor to a 12" Dobsonian. Due to the Bortle 8 light pollution at his home and the general light pollution on Long Island, Ed has researched the many ways of finding things in the sky. He has identified 7 methods and used 5 of them. His presentation will share what he has learned and will be suitable for beginners as well as experienced astronomy hobbyists. https://asliclub.org/ https://spncastronomy.wixsite.com/7-p...
