NGC2467, a happy accident
Posted 10 March 2013 - 12:56 AM
Star hopping back to M93 to show him, I took a wrong turn at Asmidiske and went in the opposite direction. However, while sweeping the area I came across a faint fuzzy that I didn't remember from my H400 sweep of Puppis at the start of the evening. (As a side note, identifying open clusters in this region is almost maddening! There are sooo many and they barely stand out from the very rich background, easy to get lost but a gorgeous view to just poke around) Anyway, pulled out the Pocket Sky Atlas, realized my mistake and identified the nebula we were looking at. NGC2467. It is marked in the PSA, but I had overlooked it in past trips through Puppis.
It's a very nice "little" nebula. At first glance it appears as a fog around an 8th magnitude star which stands out pretty well in the FOV. Very similar to the look of a dewed up eyepiece or mirror/glass. That was my first impression, but I immediately noticed that none of the other stars had any haze around them. After studying it for a bit I noticed that the haze, while almost exactly circular in shape, was not centered on the star, more was to the west of the star than to the east. It appeared to be of fairly constant brightness over the entire nebula with some patchy spots here and there that were a bit darker.
A happy accident for sure. Check this one out if you haven't yet, and be sure to look up some pictures online, it makes for great images. I probably would have missed out on this one for awhile had I not taken that wrong turn.

I need to re-observe this one. It has been quite a while since I looked at it. My notes with an 8" SCT. "Round nebula easily located with help of SAO atlas. Fairly easy. P Filter [Skyglow Filter] definitely improves contrast. Embedded in faint matrix of stars (8 seen at 170x). with 1 brighter one. Reminds me of Owl Nebula but not quite as bright. Stars are from open cluster Haffner 18. [Actually Haffner 18 is superimposed but this object is a combination of open cluster and nebula.]"
Interesting info about the Haffner cluster, Thanks!

I also viewed NGC 2467 and many other great southern deep-sky objects through my friend Tony Donnangelo's 20" f/4.3 Starmaster Skytracker Dob and my 12.5" f/4.8 Starsplitter Dob during our stay at Chiefland.
