I have found (as with any mag.2-3 object) that observing its' pass in binoculars shows an excellent color 
contrast between Lacrosse 1 and the stars.  Yes, I agree that Lacrosse 1 is not "ruby red", I perceive a more 
definite orange hue to it.  An interesting question, for those who have watched Lacrosse from its initial 
deployment (Ted are you there?) has its' color faded over the years?

Clear skies...Bill
