WR134 is a Wolf-Rayet star in Cygnus. It has stripped of part of its shell that is driven away by the massive radiation of the star. The shock front forms a bubble that glows in Ha and OIII light.

 

I had one short night for Ha and not enough Oiii and another one for more OIII and RGB for the stars. In total the image was built from 6.7 hours of light.

full size:           get.jpg?insecure

 

In the processing I concentrated on the bubble and left the well structurated Ha background stay back. By the way, the OIII bubble does 360° and the Ha makes only 120° of the bubble circle at least in my case. You can see that in the 6-10 o' clock region of the bubble where the ha glooms through from behind.

 

Hope you like it!

 

C&C welcome like as always.

Practically perfect to my eye.  waytogo.gif

 

Rarely do I see an image superior to an APOD of the same object but yours is.

Hi, Pete,

 

Great result! bow.gif

I love the circle of the OIII; not seen so good in any other image! waytogo.gif

I had no idea the OIII extended around in a full circle.  Amazing capture!

Really great image. From your description, it’s Like a planetary nebula for big stars :)

Cheers,Ian.

Yeah, this star-guy knows how to make a really big bubble before it bites the dust waytogo.gif

Your great image had me comparing this rendition to another similar object,  Thor’s Helmut.  Striking how similar they appear, again thanks to your efforts.

Glad you like it!

 

Despite the similarities - these shock fronts are phantastic objects, aren‘t they- WR134 was much more challenging to process. The strong Ha in the background tended to suppress most of the Oiii in the bubble outline.

I am going to try to image that tonight, using my Orion 120ST @F5 and @F3.15 with a Meade F6.3 reduced corrector and my new Optolong L-eNhance duo narrowband filter, with my ASI 294MC and ASI178MM cameras.

What an amazing image!

Thank you Sir!

Then I wish you a good hunting with your double shotgun, David smile.gif .

 

According to my experience with WR134 it might be a problem to have Ha and OIII together in the same frames. The Ha in the background is so strong that it might kill the OIII without the opportunity to weight them separately in the post processing. The OIII in the weaker part of the bubble is really! faint while there is enough background Ha present signal to drown it.

 

What do you think about the idea to split the channels later in the RGB stacks to enhance the OIII signal in the blue channel before combining it again?

 

Anyway I wish you a clear dark night!

 

Cheers

Pete

I had not hoped do dig it out but it finally worked, Kevin. Thank you for the flowers smile.gif

Yes I really love it. It has some minor flaws but it is indeed very sharp.
