Thanks to those who recently corrected my math errors in calculating
pixel size. I now have another question. From what I have been
reading, recommendations are to utilize a pixel size that is half the
"seeing". The article I read stated that at mountain top level seeing
can be "1" while at sea level it can be as much as "4". My question is
this - what do these "seeing" indices mean and how do you go about
calculating them for your particular viewing location?
