The remote quasars
adjacent were imaged in the autumn of 1998
via a 30cm Meade XL200 with Starlight Xpress MX9 CCD camera. Included are
two gravitationally lensed by intervening
'invisible' galaxies which either split the quasar into two i.e. Q0957+561
or like APM08279+5255, receding at 92% velocity of light and some 12 billion
light-years away, brightened by a factor x20 to shine like 5 quadrillion
suns - truly Lighthouses at the Edge of the Universe.
The 'z' value is a measure of recession of the quasar as deduced from a
shift of the spectral lines towards the red are fully explained on the
main quasar page.
