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 http://www.narrowbandimaging.com/hc1_planetary_page.htm |

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.

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!

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 ----- Original Message ----- From: "George Normandin" To: "Richard Crisp" Sent: Monday, November 20, 2006 5:41 PM Subject: ASTRO: Yet another Planetary Nebula discovery ----- Original Message ----- From: "Richard Crisp" Newsgroups: alt.binaries.pictures.astro Sent: Friday, November 17, 2006 10:49 PM Subject: ASTRO: Yet another Planetary Nebula discovery Mike Howell and I have been collaborating as of late in the quest for uncatalogued planetary nebulae.

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!!
