Description:
IC418 is a compact planetary that appears quite unusual through a large scope.
The planetary has a distinct red colour. The cluster appears to be about 30"
diameter, and has a very bright central star at 10.17 magnitude. Direct vision
gives the planetary an annular appearence and a pale crimson shading. Averted
vision changes the view slightly as the planetary has an even surface brightness
and appears to change clour to pale aqua. The central star dominates the view.
The outer edge of the planetary is the brightestand the nebula is visible as a
star in my 90mm finder. I did not use a filter to observe the planetary as I
have found that it does not improve the view of the object. THIS is a MUST
