Talk about going DEEP! 10 BILLION light years! I must say that this is an impressive capture, for EAA viewing especially and look at that exposure! WOW only 4 seconds and you capture a gravitationally lensed Quasar! Just check out this snip from Cloudynights.com for yourself! All with an Evolution C8@f4.3 and ASI290 Mono x2 bin using just 4s exposures. Yep, you read that right. Blows me away how far Electronically Assisted Astronomy (EAA for short) has come for us backyard stargazers. http://www.cloudynights.com/topic/564807-twin-quasar-qso-0957561-in-just-4s-exposures/ 1 Follow this topicTwin Quasar QSO 0957+561 in just 4s exposuresStarted by Astrojedi, Yesterday, 04:26 PMReply to this topic6 replies to this topic .#1 AstrojediSurveyor 1topic starterPosts: 1662Joined: 27 May 2015Loc: San Diego, CAPosted Yesterday, 04:26 PMTwin Quasar QSO 0957+561 A/BOne of the first and most well known examples of gravitational lensing. A tremendously massive foreground galaxy YGKOW G1 is causing the lensing due to which we see 2 projections of the same distant quasar. These objects were first discovered in 1979.Based on measured redshifts the quasar lies at ~10B lyrs and the lensing galaxy is at ~4B lyrs. The really interesting thing is that the light from B component reaches us 14 months later than component ...
