[ATM] Light scatter on a mirror surface

["Russell Jocoy" <russjocoy@hotmail.com>]

To all on the list:

    This listing of theories and facts of how much light is diverted from 
it's intended path is an exercise in things that can be improved on , but 
Not as of yet. Reflective coatings, aluminizing, glass that is happy with 
refraction, and anti-reflective coatings are basically "new".  These will be 
improved on and this will increase the light to the eye, or camera( Decrease 
the scatter). To go to the atomic level is stupid, the surface of the "best" 
telescope mirror" at the atomic level looks like the Sahara desert on a good 
day.  Don't get me wrong, the scientific venture into how to reduce the 
light scatter is a just cause , but let us not forget the other variables 
that can destroy more than this minimal light scatter.
   Collimation, (this is a big light sucker),  Improper baffling, or none at 
all,  Light shields, whether cage or truss application.   There are many 
variables and I have only listed a few .. Light scatter is important, but 
let us control the easy ones first, and then if our eye could even detect 
the difference in the light scatter on the surface of a mirror, we can go 
see our "eye doctor" ( this is another variable)          Just my opinion...
