Quasars around NGC 3628
Image of the Hamburger Galaxy (NGC 3628) acquired with SPA-2 (via a one-click observation).
I saw articles and pictures of several quasars around NGC 3628. I wondered whether these QSO's were also visible in my (processed) image & yes, they are...
QSO "Wee 52" with a redshift z = 2.43 at an estimated distance of about 10.5 billion lightyears is probably the most distant object I ever spotted in my astropics (as far as I know...).
