Quasar PG 1634+706: spectrum and redshift
On 24 July 2013, the Celestron 14″ robotic unit was slewed to a very distant source, quasar PG 1634+706 with the goal to grab a spectrum and measure the redshift of this astrophysical source. This...

After the very positive results with quasar 3C 273, we tried to get a spectrum of APM 08279+5255. This quasar is shining at mag. 15.2 and is located at a distance of 12 billions...
Few things are able to capture the imagination of stargazers as the idea of distance of a cosmic object. While looking at that likely pale spot of light, so hard to see with their...
Recently, the Celestron C14 robotic unit has been equipped with a SA100 diffraction grating, making possible easy, low-res spectroscopy. After a couple of successful tests, we managed to measure the red-shift of quasar 3C...
