This is quasar 3C 273 with jet imaged from Melbourne, Australia with EdgeHD11 at f/10. 56 x 5m exposures with C filter and ASI1600MMPro, 0.28" per pixel.
This is the first quasar identified with a large redshift, and it required the Palomar 200" to image the jet at the time, around 1962-3. Two short papers were published in Nature about the discovery in 1963 by Maarten Schmidt and J. B. Oke, available
here. A nice summary of the discovery is
here and it shows the image from the 200".
It's now about 60 years since the discovery and it's now possible for amateurs to image the jet from their backyards. There are a few other examples here in Astrobin. It requires fairly good seeing and a dark sky, but I have fairly strong light pollution at 18.5 mag per arc-sec^2 so I needed many exposures. fwhm's ranged from about 1.6" to 2.8" during the two evenings of imaging, and all exposures were used in the stack - with a continuous run on each night and 100% yield.
This image has no processing, sharpening or denoising and just has levels applied in photoshop.
The astrobin plate solve is wrong and it shows the wrong location and pixel scale. This is 0.28" per pixel. Not sure how to fix the astrobin info.
