A tiny planetary in Puppis

[Paul Haese]

NGC2440 is a tiny planetary in Puppis. It appears about 74" x 42". In one orientation is appears like a bow tie. The central star is a white dwarf with a surface temperature of around 200,000 kelvin.

This image is composed of Ha OIII LRGB with 14 hours of integration time.

There appears to be a faint halo around the object, which could be of further interest with a longer focal length / greater image scale.

Nice one Paul. I don't normally comment on AP as I don't do it myself but I like planetaries and really like the structure you've captured in this tiny one I've not heard of. Cheers, Richard. :thumbsup:

That is one interesting subject Paul, well captured.

I dont normally comment either ..but as I was recently trying to see this 9.5 Mag Planetary visually, just directly south of M46 ..seeing how terrific. this image is..Im inspired to have another look for any detail ....thats if the clouds finally move.

very cool shot paul - i think i'll check this one out with the dob! thanks for sharing.

Nicely done Paul. Nice to see someone else is doing planetary nebulae. As a matter of interest the central star of NGC 2440 is the hottest White Dwarf known at about 200,000 degrees C.

Cheers

Nice picture Paul, looks like a little bowtie..... ;)

[gregbradley]

That's a good catch Paul. I like it. Its small but rather bright.

I haven't seen that one before, Paul. Great detail for such a tiny, but very interesting, object.

[joelshort]

Very nice! I haven't seen that one before either.
Remember the 'machine' from the movie "Contact"? That's what it looks like to me. It looks like it's spinning around in space! :)

[Andy01]

Was that with your new GSO? Nice image!
Must be teeny tiny or a zillion miles away though - be interesting to see that one through a Long FL 'scope.
Well done :thumbsup:

That's a fantastic photo! Just saw on Stellarium that it's mag 18.9 - a visual challenge for sure. Apparently also called the Albino Butterfly Nebula, Burning Ember Nebula, Bat Nebula, Kiss Nebula, and Little Lips Nebula. Sounds like anyone can name a nebula these days.

[bigjoe]

Should be 9.4 Stellerium makes some odd rare mistakes.

Nice one Paul. Haven't seen that one before. Interesting structure. Good job resolving detail on such a small target.

[Bart]

Nicely done Paul, and great detail for such a tiny target.

[gaseous]

Thanks Joe, yeah I noticed your earlier post and figured you're probably less likely to be in error than Stellarium. Might have to give this one a crack with the 16" now that it's achievable.

Very nice detail in the planetary Paul, that new scope of yours seems to be eating up the photons quite nicely.

Wow...what a beautiful looking object!

Great photo Paul.

[Paul Haese]

Thanks everyone for the comments. Much appreciated.



That is interesting about the temperature because I also read the same but then when I imaged the butterfly nebula or bug nebula I read this also had a surface temperature of 200,000K. I do wonder which one is the hotter of the two.

[Camelopardalis]

That's a real beauty with a twist Paul, well done :thumbsup:

[Atmos]

The typical white dwarf when “created” is going to be around 200,000K but because it doesn’t create any of its own energy (no longer undergoes nuclear fusion), it’ll just slowly cool down.

As most planetary nebula dispurse in 10,000-50,000 years, one could argue that most white dwarfs seen with an associated planetary Nebula should be of approximately the same temperature.

:thumbsup: Unique looking DSO, well captured Paul congrats

[Stevec35]

I probably should have said "one of the hottest" although I seem to remember a visiting speaker at a society meeting saying it was the hottest then known

[Shiraz]

beautiful image Paul - outstanding detail. cheers

[markas]

Beautiful detail and colour!

Saw this one through my 16" dob last night. The seeing was pretty poor, but you could definitely detect its non-spherical nature. I couldn't detect any significant details or colours, sadly.

[Paul Haese]

Thanks guys for comments and thanks for the clarifications Colin.

[topheart]

A beautiful gem indeed!
