A trio of telescope types in twilight: The Celestron NexStar 6SE Schmidt-Cassegrain, the Sky-Watcher 8-inch Flextube Dobsonian, and the SharpStar 76mm EDPH on the Sky-Watcher HEQ5 mount, as examples of the three main optical systems: catadioptric, reflector and refractor; and three main mounting systems: fork, Dobsonian and German equatorial. Also showing telescopes for visual use (on the left) and the refractor for photographic use, with camera. Also showing computerized GoTo with the Celestron and HEQ5 mount vs basic manual with the Dobsonian. Taken for book illustrations, August 27, 2020 from home at twilight.
A selfie using the Meade ETX90 Observer telescope in the backyardunder moonlight night, August 6, 2020. I am pointing at M31, the Andromeda Galaxy, M31, and the telescope is pointed at it, too. A single exposure with the Nikon D750 and 24mm Sigma lens. I am illuminated only by the red LED light on the ETX control panel and on the hand controller.
