RCW58 now with added high rez data

[gregbradley]

Wolf Rayet nebulas show the power of those stars.

This is a rarely imaged nebula. It was rather poor seeing plus it was a bit low in the sky so stars are a tad blurry but you can see the nebula well enough with its radial spikes.

Nice one Greg, I agree the radiating spikes make the object interesting kinda like a mini Helix. I considered shooting this myself recently...too many objects not enough lifetime :rolleyes: :thumbsup:

[Atmos]

WR stars are certainly an interesting breed, would LOVE to see what that looks like after it goes KABOOM!
Nicely captured Greg, not one that I have seen imaged before :)

[Placidus]

Excellent work, Greg. I recall that's a difficult one to separate from the starry background. Structure nicely shown. Pleasing NB-Colour combination too.

Best,
Mike

[topheart]

Awesome!
Well done Greg.

Tim

[gregbradley]

Its an interesting one for sure. I probably will revisit this one with the CDK17. I already got some nice Ha data with it I should add to this.



Its a bit of an obscure object.



Thanks Mike.

Greg.



Cheers Tim.

Greg.

[Paul Haese]

Well done on this one Greg. Colour looks good with interesting detail.

[RickS]

The spikes certainly are very reminiscent of the Helix. Nice catch, Greg!

[Ryderscope]

A nice one Greg and a very interesting object.
Definitely worth placing on the capture list.

[gregbradley]

Thanks Paul.



Cheers Rick




Its an interesting object for sure.

Greg.

[plantnerd]

Great stuff a really cool object and nice colour

[gregbradley]

Thanks Luis. Sakib gave me a list of Wolf Rayet Nebulas after I posted an image of SH2 308 bubble nebula. Its been helpful.

Nice RCW58 Greg You've managed to blend your HA data in nicely.

I noticed you have some OIII data in there I have been trying to to process about 10 hours data i pulled for RCW58 i have a few hours of OIII at 12nm was trying to get some of the blue outer shell but with 3 hours integration showed no structure at all :(.
Did you notice any real benefit to your OIII?

[gregbradley]

Hi Michael,

The O111 showed almost no structure. A faint outline at best

Greg.

[Regulus]

Nicely captured Greg. It would be great to see a sharper image of this for all that interesting structure. Will you be having another crack at it?

Trev

[gregbradley]

Hi Trev.

I have some CDK17 Ha data I plan to add. That has more resolution to it. I might add some more later on from the CDK.

Greg.

[gregbradley]

I added 3 hours of CDK17 Ha data taken at F4.45 on Proline 16803.

Its brought out a lot more detail.

[Atmos]

It stands out a lot more, really nice Greg :)

[gregbradley]

Thanks Colin. The CDK data was quite a bit more detailed. I might take more soon if its still up.

Greg.

[Geoff45]

Nicely captured Greg. Those RCW objects are often very interesting. We should pay them more attention.
Geoff

[gregbradley]

Thanks Geoff. It is an obscure object. Sakib sent me a list of them to image over time.

Greg.

[Placidus]

:thumbsup: The fainter structures in the nebula are clearer and more defined now. Also, the extra exposure has allowed slightly more contrasty presentation.

[Ryderscope]

Wow, it does jump out more. Agree with Geoff's comment as well that these RCW objects need more attention..

[Retrograde]

Very nice image of a rather obscure object Greg. The additional data really does makes a difference to those fine details.

[Regulus]

yep, that's improved the detail somewhat Greg. it's an amazing structure, and one I hadn't seen before.
Cheers - Trev

[gregbradley]

This one is one of the better RCW objects. Some are a little boring.



Thanks. The CDK plays well with the Honders data so its a good trick to have up my sleeve.



It is an interesting shape. A bit like the Helix without the O111 nebula.

Greg.

[Shiraz]

haven't seen that one before - intriguing object and pleasing image.

The detail is very good - you must have been some good seeing

[gregbradley]

Thanks Ray. The seeing was probably fine but the detail is mostly coming from the CDK17 and it does a pretty good job usually getting detail.

Greg.

[Ross G]

A great capture Greg.

What a beautiful object!

Ross.

[gregbradley]

Thanks Ross. I'll definitely do another version of this next year when it comes around again. Its quite a find.

Greg.

[Slawomir]

Now, how did I manage to miss his beauty?!

Really nice work Greg, I think it is great you took time to image a much less popular target. Please keep them coming. :)

[gregbradley]

Thanks Suavi. I intend to do some more obscure stuff in amongst the more usual targets. It keeps it interesting.

Greg.

[RB]

I missed this too. :confused2:

Lovely shot Greg, a very interesting object.
Thanks for sharing.

:thumbsup:

RB

[gregbradley]

Thanks RB. Its an interesting object. A bit like the Helix without the O111 aspect. The radial spikes are like the Helix though.

Greg.

[Peter Ward]

Not sure what to say here....a very interesting object for sure :thumbsup:, but the dark sharpening/rebound rings around the stars is not a good look for me.

Processing should not introduce things that simply are not real....and sure..there is no legislation here...simply my fearless and frank 2 cents worth :)

I'd really like to see more of this object through your CDK's optics.

Lord knows, the seeing effects at that focal length can be an absolute pain...but the rewards when it co-operates are sublime. ;)

[gregbradley]

Thanks Peter. Its a little since I processed it but I don't recall doing any decon or sharpening on stars. In fact I did very little processing on it at all. What is rebound?
Seeing was poor and star sizes were large and probably the red subs had larger stars as red was most likely taken when the object was lowest (it was pretty low to start with not being the ideal time to image this one). But I will keep your advice in mind. I agree stars are best left to minimal processing and its better to concentrate on the data acquisition making sure everything there is working at its best.

Greg.
