it has already been posted to AMASTRO, more than one person has confirmed it
visually and there's a pretty signifcant amount of [OIII] in it.

It may or may not be a planetary but it is definitely there, shows up in DSS
but doesn't show up as being catalogued in Vizier nor do any of the stars
show up in Vizier either. It is all very curious because it is faint but not
that faint and in tricolor emission line images it shows up very prominently

Mike Howell and I have been collaborating as of late in the quest for
uncatalogued planetary nebulae. We found one on Nov 4 in an image that
Mike took and one that I took. So we decided to call this one
Howell-Crisp1........


Richard,

It sure looks like it could be a planetary, or perhaps a small patch of
H-II?

I believe that Brian Skiff at Lowell Obs
(http://www.lowell.edu/People/bios/skiff.html) use to maintain a list of
potential planetaries. He may be interested in imaging this with one of
their large instruments. You should give him a call or e-mail. Mike
Schwartz (http://www.tenagraobservatories.com/) the supernova guy may be
willing to let you order up a single image with his automated 32-inch RC.
Normally he sells time, but he has offered to let me use it a little in
the past for free. I wish that Mike had a spectrograph.

Good luck with your hunt for nebulae!!

both of us found it in widefield images and I have since taken an image of
it using the Stinger 450 cassegrain on Nov 9 but the seeing was very
unsettled that night, there was a ton of moon and some thin clouds and
lots of dew.

Well rest assured that when the weather gives me the chance I will return
to it for a better high resolution image

In the meantime we will have to settle for the discovery shots, my high
res shot taken under poor conditions and some images I put together from
the DSS

I attached the image I made from the DSS F, J and N plates since it looks
the best and also attached the POSS F filter image as it is the best high
resolution image of it so far
