Hi Monte,
You would certainly want to avoid the areas of the sky that were scrutinized in
the relatively recent (Aug-Sep 2005 release) MASH survey (Parker et. al.)
Conducted in the H-alpha, it discovered something like 905 new or likely galactic PNe,
a 60% increase in the number previously known.
There are obviously plenty undiscovered galactic PNe out there just waiting
for those with the necessary skills to find and verify them.
Amateur observations of the new MASH objects would also be interesting.
You can find the catalog at the usual archives online. I also processed it into
three Argo Navis loadable user catalogs - differentiating those that were
true Pne from those that were likely PNe and those that were possible Pne.
See
http://tech.groups.yahoo.com/group/a...alogs%20/MASH/
(Group registration required). Though these files were meant for loading into the
Argo Navis, you will see the plain text format is relatively self-evident for human consumption, including the
all important J2000.0 RA/Dec co-ordinates. They also include survey observer's notes in the last field.
