 Hi there Jack,
 At 0.9c, any wavelength of light would be red-shifted  by a factor of 4.4. 
Thus the most sensitive colour (yellow-green) at 5.6*10^-7 m emitted from 
this object moving away from us, appears  to have a wavelength of 2.4*10^-6 m 
which is in the infrared part of the spectrum.   Your eye would not see it.
However other instrumentation could.  There are object moving away from use 
faster than 0.9c, however they are beyond the particle horizon.  The 
particles horizon is caused by the finite age of the universe.  Light has had 
only 15 or so billion years to move about but the universe is far far larger 
than 15 billion years...Ets beyond the particles horizon?  Completely 
possible, how they could never have reached us.
 Regards George
Oh..my response to a message takes a number of days to get through...
