While taking a break from comet gazing yesterday morning, I visited old friend M-46 and its neighbor planetary NGC-2438. The neb stuck out like a sore thumb in my 12" without any filter. The O-III and NPB filters both made it look fake, it was so well defined.

Thanks, Ken, I might have to add that one to my list.

This is a fun and interesting pair. If the seeing is good the PN takes high power well.

I "rediscovered" this last weekend when I was sweeping the Canis area. Normally for my home most of that area is obscured by trees adn I don't even bother. At my dark site the southern horizon is unobstructed.I think a decade ago when some trees in my backyard were shorter, I discovered this one in my 6". I had forgotten all about it! I checked this one out for about half hour before turning to Jupiter as the sky started to lighten before dawn. Really fun and interesting combo of objects.

Once when I had my AR127 out in the backyard, I was looking at M46 (a beautiful OC btw), but couldn't see the PN. I popped in the O-III, easily found it, then took the filter out. Once I had flagged the exact location with the filter, I could discern it without, though faintly.

Can't beat the location of it!

When I observed M46 I didn't even realise there was a PN there until I looked through the EP!
Lovely object!

I don't know if I would call it exactly "one of the easiest". I have a hard time seeing it from my moderately light polluted observing site (orange zone) without using a UHC filter.

I'm fortunate to have green skies, good eyes, and 12" of glass. I haven't looked through my list of planetaries that I've seen, but I think it's about third easiest to find and then see behind M-57 and M-27. (This will probably bring on a chorus of howls about all of the easier ones that I've missed...) :question:

Mainly due to my dark home sky, I can honestly say that Ngc 7293 has been the easiest PN for me to find. On my first attempt to locate it, I was surprised to see it immediately in the 9x50 finder. Never yet saw Ngc 2438 or M46. Will try soon. :coolnod:

Yeah Ken, I can give you some I find easier to see - NGC 3242 (Ghost of Jupiter), NGC 7009 (Saturn Nebula), NGC 2392 (Eskimo Nebula), NGC 6210 (Turtle Nebula), NGC 7662 (Blue Snowball), M76 (Little Dumbbell). There are some others that I can't recall off the top of my head. I think part of what makes NGC 2438 easy is its location. If you look at M46, you're looking at the planetary. You just have to spot it against the stars of the cluster. Whereas, the others I mentioned stand alone against the sky and stand out well. Just how my eye sees it anyway. Irregardless, I truly do like the object within an object scenario.

I love pairs. M-35 and its faint OC neighbor NGC-2158, the Coathanger and its OC neighbor (NGC-6802) on the end of the right hanger tip, galaxy NGC-6946 and OC NGC-6939.

Yep! I do agree with you here. These are some of my favorite, easy planetary nebulas too. In fact it was only about four years ago that I was looking for NGC objects with my binoculars and saw a star where NGC 3242 was suposed to be located and thought could that be the Ghost of Jupiter? Well, I got out my little AT66 refractor for a look and sure enough it was the Ghost of Jupiter. Now that is an easy one.

I agree--very pretty. NGC 2158 looks like a cross between a globular cluster and a nebula.

I had similar experience. I was casually star hopping to the GOJ once with the Z10, and noted a star in the correct location in the 8x50 finder. Moved to the EP and yep, that was it. It is one bright planetary, and really seems to push its way through the sky glow quite well.

+1 Don't forget M46 and NGC 2438. Quite possibly my favorite pairing of all time.
