Resembling a hot chilli these superheated blue tendrils of ionized oxygen are remnants of a spectacular supernova that occurred some 11,000 years ago.
Located in Vela some 800 LY distant, this small isolated section of this vast region silhouetted against a background rich in Ha seemed worthy of attention it’s own right - as after an exhaustive search, there don’t appear to be any stand alone studies online of this beautiful waveform.
Photographed over three nights from my light polluted suburban backyard in Melbourne.
Acquisition was made using Stellarmate on a Rpi4 😊
Absolutely beautiful Andy I wish I had more time to wait out the conditions in Melbourne to acquire more images, yours are an inspiration.

I'd guess you've processed the nebulosity independently to the stars and gave it a soft, buttery look....
A strong image regardless.

Thanks for nice feedback Nikolas, Graham, Karlz, Mike, Peter & Bart!
Yes Mike, nice to find something new and Vela keeps on giving!
Peter - regarding processing I was keen to maintain the gaseous appearance of the O3, so I did the following steps...
>Pre-process / calibrate subs, flats, darks, dark flats & bias in APP.
>Remove stars from O3 & Ha masters with Starnet++
>Minimise noise using Topaz Ai (but NOT create any artificial structures!)
>Process RGB independently to create nice stars
>Layer all the masters in PS-Lighten mode
>Hue/Saturation O3-Blue, Ha-Red
Bake until done!
Cheers all,
Andy

Given I do most of the cooking at home and my love of slow smoked meats on the BBQ, and crispy salmon & salads, my wife would likely agree Peter! Cheers!
Thanks Rodney!
I've created a new version with Akira Fujii effect stars, be interesting to hear your thoughts on this.
I can see that from an artform and presentation perspective the Akira Fujii effect stars can have a place and can provide a soft and somewhat pleasing affect. Kind of like applying a soft focus filter to the stars and enhancing the colour.
For me though I bump in to the need to have some realism particularly in the star field. I feel that some management of stars to stop them blowing out and a little extra colour saturation whilst still being kind to the underlying data is ok. I'm fine with getting rid of the stars altogether if it allows the detail in the nebulosity to come to the foreground.
I guess that the discussion points may stem around whether it is ok to remove stuff that is there as opposed to including stuff that isn't. All in all though I think that it is an important topic that we continue the discussions on as it ain't going away and time soon
