Here is NGC 2467 in Puppis,
processed by synthesizing the
green channel from the Red
(Ha data) and Blue (OIII data)
in Photoshop, using the
method outlined by
Steve
Cannistra
.

This object appeared on APOD
in 2005, from data obtained at
the 8 meter scope in Gemini
South...just a couple of miles
from where we imaged it at
CTIO. The
Gemini South
image
also appears to be from
narrowband data. Putting
aside comparisons of the
choices in color palette, I'd say
our 16" stacks up pretty well to
their 8 meters in terms of
resolution?
