Rosette core

[Placidus]

What lives at the heart of the velvety rose? With the heat and the clouds (and those damned native drums), just two hours each in H-alpha (yellow) and OIII (blue), at a toasty -25C because that was as cold as the camera would go. Lost three subs to cloud. But for all that, the seeing was pretty good and the image is quite sharp in parts.

Big one here. (www.mikeberthonjones.smugmug.com/Category/Star-Forming-Regions/i-JXcH6bb/0/O/Rosette%20core%20Ha%20OIII%202hrs%2 0each.jpg)

For one who once thought about being an anaesthetist, this looks very reminiscent indeed of the view of the vocal cords (toward the top) and the dark trachea beyond, seen during intubation. A happy, reassuring sight. If not, it's a worm-hole leading to somewhere interesting.


Toward 9 o'clock is a series of gargoyles in blackest dust, showing sharp edges, and being eroded by the brilliant light from the cluster.

Above them, toward 10 o'clock, is a set of shock fronts like metallic gold.

The most memorable dust lane forms and upside-down Y or wish-bone at 6 o'clock.

Toward 3 o'clock is a completely different set of shock fronts, bright in OIII, a angry blue-ringed octopus perhaps. Some shocks are very thin and fine, and intensely ultramarine, adding to the general opal-like effect.

There are some hot pixels and other bright artefacts about - as mentioned, camera temperature control was not so good, and the darks don't properly match. They can be easily rejected statistically when we get more clear sky.

Fantastic image there MnT! A lot of detail showing up and a relatively clean image, just needs, as you say, some more clear skies :)

[DJT]

I like the Fov here because you can really pick the details in the dust and as the centre is quite bright, less noise.
To me though, between 6 and 9, you have the hound, the panther, the falling donkey and the witch on the motorcycle.

iMaging this as well, wondering if it's worth looking at Sii?

[Paul Haese]

Great stars and detail MnT.

[Placidus]

Thanks, Colin. Clear sky came last night, but the moon was exactly where we wanted to photograph. How rude!



Cheers, David! We had fun finding the little creatures that you mentioned. The witch on the motorcycle is particularly fine.

The SII might need 2x2 binning.




Thanks, Paul. Needs more work. Nice to have at least something to show we're still alive.

Best,
MnT

Thanks for the opportunity to journey through your image MnT. In my case I found a dove that has been captured in mid flight at about the 12 O'clock position.

[Peter Ward]

Beautifully resolved...maybe the colors could be more saturated :question:

P.S.
I can only see a fish swimming toward me, but that's all I ever see with a Rorschach test :)

[RickS]

Great image scale and detail, M&T! You captured the Screaming Lady nicely.

Cheers,
Rick.

[Placidus]

Thanks guys for helping find a treasure-trove of extra goodies in the image.



Thanks, Rodney.



Cheers, Peter. We tried a more saturated version. Works. We'll do that for sure when we get more data. The fish suddenly leaped out when we looked at the thumbnail.



Thanks Rick! :)

A fantastic interpretation - amazing contrasts......

Well done M+T!

Cheers,
Tim

[Regulus]

Ghostly. Great detail, and an enjoyable photo.

[Placidus]

Thanks, Tim. We are much encouraged.



Cheers, Trev. Glad you like it.

Fascinating new view of an often seen object.
Lots of interesting sharp details there I havn't noticed before.

Not sure about the colours though - what's the old saying "blue & green should never be seen, without a colour in between".

But maybe it's just me :)

Great shot guys!

[Placidus]

Thanks, Andy!



I think you're far from alone, but I hope to reassure our fussy grandparents, mine included, on the blue-n-green score by posting regular pictures of palm trees on the beach at Daintree, with the tree tops against a sparkling sea and sky, proof that our grannies and great aunts are just being traditionalist, rather than tapping into a deep truth of nature pure.

Hopefully we'll revisit the object and get some hints of SII which we can map to red.

Very best,
Mike

[SpaceNoob]

Great detail and I love the view. It's like looking out the window of a spaceship cruising through the Rosette.

[Slawomir]

Wow, I love sharpness and detail in your image Mike. Really really nice work:thumbsup:

[Placidus]

Thanks, Chris. Nice thought.



Thanks Suavi. That's very encouraging. Great target for a mosaic if there were enough clear nights.

Cheers,
M and T

Nice core Mike. Very well defined fronts as well. :thumbsup:

[strongmanmike]

Wow, certainly plenty of detail to savour guys, lovely :thumbsup:

Don't get me started on how many things I can see in the Rosette :face:

Mike

[andyc]

That's a bit jaw-dropping. Spectacular new view of a famous object, and the details around the globules are a treat. You might think you need more data... I'd put it on my wall! I'm looking forward to you adding more...

[Placidus]

Thanks Marc, Mike, Andy. Feeling a bit better about an otherwise under-productive hot season. It's interesting that the problem with the summer has been the almost continuous cloud. The seeing, when there's been a break in the cloud, has been not so very bad at all.

Cheers,
Mike
