Looking back 12 billion years - Quasar image and spectrum

This time of year it is traditional to look back over the past year so I
thought I would try to go back a little further! With a redshift of 3.87 and
a luminosity of over ten million, million suns, Quasar APM08279+5255 is one
of the most luminous and remote objects accessible to amateur equipment. We
see it as it was just 1.6 billion years after the Big Bang. I used a Star
Analyser diffraction grating, my SC3 modified webcam and VC200L to make a
measurement of the redshift. See the webpage for full details.
