Here are some observations of IC 418.  Neal's correct when he said I got
excited when I first viewed this one, I nearly fell off the ladder.  (Good
thing it was at low elevation!)
         #2187  12/07/96  SCOPE 32          4  6  HIGH KNOLL
20N (183x)  Spectacular small PLA with a very bright blue central star
            surrounded by a copper colored sharp edged nearly circular uniform
            annulus.  Quite dark inside the ring, next to the central star.
         #3532  01/24/98  SCOPE 17.5 ALTAZ  4  4  SONOITA
35P ( 57x)  Quite small at this power, a fuzzy looking blue star with a tiny
            red ring surrounding it, the color just detectable.
20N ( 99x)  About the same, the color is subtle but clearly red.  The feature
            appears to darken around the central star.
         #5468  11/16/98  SCOPE 17.5 ALTAZ  4  7  SONOITA
13N (153x)  Quite a lovely PLA, excellent view at this power with blue central
            star and a sharp edged reddish edged slightly oval disk.  Looks
            darker immediately around the star.
         #5469  11/16/98  SCOPE 32          4  7  SONOITA
20N (183x)  Red color more easily seen than in the 17-in.  The dark space
around the star seems smaller.
