Default ASTRO: Yet another Planetary Nebula discovery

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

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

Richard,

congratulations on you discovery. I bet you will put a lot of exposure time
into the "final" version of this nebula :-)
As I am sure that you can do better than the DSS (conditions permitting of
course) this will not only be a shot of a "new" object but also a pretty
picture.

Stefan

Thanks Stefan and others

I have great hopes for clear skies tonight

I need to wrap up Jones 1 and want to log some more time in Crisp1 and also
Howell-Crisp1

It is getting to the point where running two rigs in parallel isn't giving
me enough capture bandwidth: I need two of the 18" rigs to keep up with all
the work that my widefield system is queueing up for me!

Cool stuff Richard... good thing you have the long FL scope to reach out and
touch these things.

yeah, here's the "production line":

I have the widefield feeder on the right and the long focal length cass on
the right

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

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!!

George Normandin
