Ngc 2818

I happened on this object almost by accident. It is an open cluster with a small planetary nebula in it. SkymapPro 6 gives the same number to both objects and then calls the PN 2818a
NGC Project calls the PN 2818 in the current database but then calls it an open cluster in the visual observation.
Nevertheless it is a nice object. The cluster is nice ~9arcmin loose collection of stars with the 1 arcmin PN on the western side of the cluster.
My colour image was just a grab of 4 x 300 sec using my 40D. I also took 4 x 300 sec pics using my genesis CCD through a lum filter only. It is much more sensitive than the 40D and shows more structure than the colour pic.
I think this object is worthy of more time if this rain goes away!

Nice image Terry, you'll have to show me again how you process images through Iris!! I have the PDF tutorial but i'd like to see how its done and ask some questions from what i have done with the M51 test image in Iris.

Cheers!

Terry,
For you interest I have placed a pdf article giving you some more background information on this cluster and planetary nebulae. Hope its useful.
These are nice pictures, and often made better when found unexpectedly.

Thanks Andrew and Terry. The PN is mag 11.5 and 85" across. Dunlop did well to see it.

Nice capture Terry.

I agree, it's now on my list.

Hey, that kind of looks like my object I had in "40D - DSO's"...maybe they're the same

Great imaging though.

Your right they do look a bit similar but I somehow think that at:
Right ascension: 9h 16m 21s
Declination: -36° 39' 3"
Constellation: Pyxis
It is a bit far south. From mid USA it will reach about 12 deg above the southern horizon. Very good challenge object.

Nice image Terry, I like the colour of it.

Definitely one for my list as well.

Cheers
