Hi List,

I can't post pic's to  the list so email me if you want me to send a group of 
NWA 998 micrographs to  you directly.

It's time to return the thin sections of NWA 998 Martian  and NWA 482 Lunar 
to Jim Strope.  (He will have them with him in Tucson and  they are FOR SALE so 
look him up).  I sat down to work on posting images to  my Gallery on 
Meteorite Times and that led to more photographing which led to  higher 
magnification, which let to "I need more light than 500W".  Anyway,  it's 1 degree out side 
so I bring the oxy/ acetylene welder in the house.   My wife about killed me. 
 I set up a lamp house to accommodate a 750W Photo  Optic Halogen Oxide Bulb. 
 I needed a heat shield on the desk to keep from  burning in.  I have a heat 
absorption filter in the train so I don't heat  the slides!  The light goes 
through MANY lenses, two prisms and one mirror  before the slide.

Long story?      Wait until  you see the pics.    These are 998 in standard 
cross polarized  light at 400X with the addition of a retardation filter.  Let 
me know what  you think.  I'm going after the 482 next.

Keep in mind, this isn't  about classification, that's already been done.  
This is about art!   Judge them on that criteria.
