This huge planetary
nebula is so terribly faint, it took me many years of shooting
it before I was able to get this deep image of its details. The
planetary was discovered back in the 30s, and has been a challenging
target for amateur sky shooters ever since.
The beautiful pink coloration
of this gem has a core of a rich teal coloration. The blue central
star is easily seen. This is the first time I have recorded two
interesting features. First, to the upper left quadrant is an
extended rim, seen here detached from the main disk. Second,
the inner teal core is crossed by two pink bands. 3 hours of
exposure were with a tri band filter, and one hour standard RGB
for the main image.
