Description:
120X-NGC3242 is a small slightly bluish oval glowing spot with a moderately
bright oval center with a twinkling central star.
220X-NGC is a small bright, bluish oval with an bright oval center that
exhibits a tiny round void with a moderatly bright star in the void's center.
The O-111 filer increases contrast, but the detail is readily observed without
it.
440X-NGC3242 is a showpiece at this power. The bright bluish oval outer
envelope shows a slight brightning of the limb. There is a bright, much
brighter center oval with a small round center hole and a bright star in the
very center. The center oval's north anse is pointed where as the south anse is
difuse and not well defined. The central hole is not completely clear, but
rather filled with a dim glow that seems dimmer than the outer envelope. The
central star is bright and it appears as a tiny blueish disc. The color of the
inner oval is bright turquoise and it is bright and crisp reminding me of a neon
sign, in it's contrast. Yes it also looks like the CBS eye logo, sort of.
