Hi to all

Generally I'm seen as having a pretty good knowledge of deep sky objects but I can't recall coming across this one before. It's quite a nice planetary, somewhat resembling a smaller M27, and surrounded by a halo discovered in 1998.

Cheers

Steve

Nice catch, Steve. I don't think I've seen that object before.

Thanks Rick. It was certainly a new one for me.

Tip of the hat to you Steve. Very cool target and ideal for the FL you are operating at. The faint shell adds an extra dimension. Something not often seen thats for sure. Thanks for sharing. Looking forward to seeing what more obscure stuff you'll bring to the forum.

Really really nice Steve.

That's something new Steve. The delicate blue coming out encourages me to get that OIII filter after all.

Thanks Logan. An OIII filter is certainly worth having.

Thanks Jase. There's plenty more obscure stuff where that came from.

Great image Steve, especially catching the halo as well!

I like PNs - but a lot of them are small, which is a pity because some of them have amazing shapes (and faint halos/shells).
I have imaged this one once, but no-where near long enough exposure - yours makes mine look really pathetic.

Tony.

Beautifully done, especially that faint outer halo.

The inner part is really tiny. You've captured superb detail.

Thanks Tony. I'm sure your exposure wouldn't have been pathetic. PNs are my favourite too but you need a long focal length. Even with my 37cm scope I usually don't bother with anything less than 40" in diameter.

That's an unusual object Steve. Nicely captured and processed.

Greg.

Thanks Greg

I can see the halo on my screen. Interesting PN. Great colour.

Thanks Paul. HaOIIIOIII images seem to work well with these objects.

I recon that should be called the Easter Egg Nebula

It's always great to reveal faint seldom seen features huh?

Thanks Mike. Yes it's nice to see the faint features. Actually I thought this halo was surprisingly easy. Easter egg is a good name. Someone else called it an opal.

Looks like an opal to me. Very nice capture Steve. New object for me. How did you find it?

Thanks Geoff. I have a UK colleague who suggests these objects but it is mentioned in Hartung (my most commonly used source for objects to image) so I'm surprised I didn't find it myself. Any planetary nebula greater than about 40 arc seconds in diameter generally stimulates my interest.

Thanks Steve.I've been a bit hesitant about taking small PNs, but after trying my hand at one or two I find that although they are a challenge, they are not an impossible challenge.

Definitely not! You also sometimes get interesting pairings between planetaries and other objects which make for interesting images. NGC 6440 and 6445 spring to mind for example.
