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.
