Helix in OIII

strongmanmike (Michael) · #1 24-10-2010, 01:25 AM

Still playing with the data set

Astronomik 11.8nm OIII filter, 36 X 15min subs

The unique explosive like OIII structures get overwhelmed by the much stronger Halpha when the data is combined, so this is what the Helix looks like in OIII only.

Here is the coloured version with the inner OIII structures retained.

Wow, that's quite a cool effect, Mike.

You can really see that 'Explosion' effect! Top stuff.

Interesting how the o111 has a much more radial effect than the hydrogen which is so clumped. ...... And I have no idea why this is so.

Intersting.

I wonder if its like that because Hydrogen is so light and oxygen is heavier. It would maintain its momentum more easily? Its easier to see it was blasted out from a centre.

Mike I love it. The detail in the core is exquisite. a big session for just OIII so it would be nice to see all three emission lines combined into what will be an image we would dream of.

Dougieeeeeeeeeeeeeee

Wow, that streaky OIII is trippy.

I wonder if other objects exhibit this as well?

Good stuff, Mike!

The OIII structure is certainly pretty interesting but quite hard to combine into the final SIIHaOIII image so that it stands out.

Striking, looks like a star burst

Well you learn something new every day. Wonder if you can see this visually with an Oiii filter?

Anyway great image Mike

Been giving this some thought, Its possible the bulk of the hydrogen was thrown off in successive shell flashes, whilst the deeper oxygen has been thrown out only with the final burst of the dying star.... You've captured something of scientific interest mike,

Yes, as I have said before it is not always just pretty pictures that we do

Ah I see, I thought it was a new set of data you were starting Off.

Love the final works and can only imagine how difficult the data set is to combine and finalise the detail.

Come on , get out and get some new data to terrorise us with.

Very cool Mike, I seem to recall at IISAC we could some of the radiating streaks in the Helix in the Mary Rose with an OIII filter. But not quite as good as that image, wow!

Cheers Rod

I can't say I noticed these particular OIII lines but I think we could see a hint of the cometary globules..? But maybe it was these lines..hmm?...I don't know.

It was a great view though I remember.

wow thats cool
