“Trifid Nebula” (M20 or NGC-6514) was named by John Hershel (1792-1871) who dubbed it the “Trifid” — from Latin for three parts or lobes — based on his telescopic observations of the divisions in the central part of the object. A single giant star in the center of the nebula powers the red glow of hydrogen gas surrounding it. The outer blue zone is starlight reflecting off of dust. The stars around the nebula are an open cluster.
Mars is growing daily in size and brightness as it approaches opposition night on 13 October 2020. On that date, the “Red Planet” will shine at magnitude -2.6 and be 22.4″ in diameter. At 5.5° above the Celestial Equator, it will be well placed for northern observers. Enjoy it while you can as it will not reach 22″ again until the year 2033! See our prior post on the Mars Opposition to learn why this will be the Last “Best” Mars Opposition for Northern Hemisphere!
Rodger W. Gordon has been an amateur astronomer since 1952 and has written over 300 articles for various amateur astronomy publications. Having owned hundreds of eyepieces, he has been known as the “Eyepiece King” of the hobby. In his long career, he has worked for Edmund Scientific, Vernonscope, Optical Techniques, and has consulted for Questar.
At the Northeast Astronomy Forum (NEAF) in April 2007, we introduced the 13mm Ethos 100° eyepiece. The overwhelmingly positive response to it at ensuing star-parties led me to explain why the view elicited so many enthusiastic “WOW!” comments in an essay on our website “The Majesty Factor – The Nexus of Contrast, Power, Field” (also on our mobile site). As an example of the enthusiasm, I included the following:
Right after NEAF, Rodger Gordon, a well-known “eyepiece junkie,” wrote me: “Definitely the finest wide-angle eyepiece I’ve ever seen. If God is an astronomer, this is the wide-angle eyepiece he’d choose. You can quote me.” Thanks, Rodger.
Knowing Rodger’s long experience with astronomical equipment, and the fact that we both own Questar 3.5″ telescopes, he sent me the following letter, written July 17, 2020, about comparing his Questar 3.5″ to his son’s Tele Vue-85. I like to call the Tele Vue-85 my “Goldilocks” telescope because it’s just the right aperture and size for everything from a quick “no excuse not to go out” observing session to a full night of enjoyment. However, if I judged telescopes by their sheer beauty and elegance, I guess I would rate my Questar as the “Majesty Factor” winner 😉 .
