I am having trouble understanding this. I thought gravitationally lens images were curved streaks. Sent from my iPhone

Most are, including these. You have to look closely at the amateur image, the resolution isn't as good as the pro image next to it, but you can clearly see the arcs. These are also incredibly dim; capturing them at all is a big part of the achievement. On Tue, Mar 7, 2017 at 10:16 AM, Joe Bauman via Utah-Astronomy < utah-astronomy@mailman.xmission.com> wrote:

If you want to see some that *aren't* curved streaks, take a look at these that are discussed in another Cloudy Nights thread: http://www.cloudynights.com/topic/492969-is-gravitational-lensing-visible-th... This discusses a free downloadable atlas called the Galaxy Trios and Triple Systems atlas maintained by Alvin Huey. It has a "sub-atlas" that discusses "bright" gravitationally lensed quasars. His atlas can be found at: http://faintfuzzies.com/Files/GalaxyTrios-v6.pdf These quasars range from magnitude 14.4 to magnitude 21.5. They include Einstein's Cross (Peg), Double Quasar (UMa), Cloverleaf Quasar (Boo), etc. I'm planning on trying to image some of these this year. Clear skies, Dale.
