[ATM] APO design

Hello,

  That scope is intended for visual use. So a pretty goog correction
  from C to F, as small spherocromatism as possible.

  The field could be narrow say 0.5 degree in diam.
  No IR or UV use because, if I use it for foto I will do some webcam
  pictures where normally I use a Baader UV/IR block filter.


  Because my Yolo is 9" in diam. I don't want a smaller scope, but it
  could be 9" if not 10" with the same focal lenght.
  The glasses where selected via price a little more expensive
  glasses are acceptable, but I am not a rich guy. That's why I have a
  Yolo.
  Thank's for the link, I knew it before.It is very useful anyway.
