GUM16 Vela SNR in HOO, RGB stars.

It's been just under 2 years since I first imaged this region (https://www.astrobin.com/s48igp/), and I've been trying to get back to it since.

However in Mid-December I decided that a 3-panel mosaic of this region was worth the effort, and it's only took ~2 months to collect 24 hours of Data! (I've also been imaging other targets as well) I had some some clearer than usual nights recently and decided to go all-in and finish off my acquisition for this target.

The Vela Supernova Remnant is a vast, turbulent looking gas cloud from a violent Supernova event that occurred approximately 11,000 years ago. This region is rich in Ha and OIII gasses that are interacting in complex and beautiful ways.


Per Panel, this image is 4hrs each of Ha and OIII, with 15min each of RGB for the stars.


This was integrated as a 2x Drizzle, processed in Pixinsight, and downscaled by 50% (back to it's original resolution) to be uploaded to Astrobin.



I highly recommend checking out the full image on Astrobin! (https://astrob.in/69tvnm/0/)


Attached to this image is the full mosaic, as well as a comparison crop from my previous attempt. It's fantastic to be able to take images like this and see how the changes in equipment, skills, techniques, and workflow have lead to (very) tangible improvements in the final image quality.


Thanks for looking, and Enjoy!

An excellently framed image of a fabulous target.

Yeah baby! Top Shot that :thumbsup::thumbsup:

Weird I know but reminds me of a close up of Lionel Murphy's nose....:P

Wow what a beautiful image and perfectly framed. Superb colour and the detail in the full-res is wonderful.

[joshman]

Thanks Greg! I chose this framing because it kinda looks like flames!








Thanks Mike! But, and I'm really showing my (lack of) age, I don't even know who that is! But google tells me he passed before my first birthday.







Thanks Martin! This definitely turned out much better than I anticipated!









Thanks Dave! I've had surprisingly stable skies when it isn't full of clouds! Perfect conditions for the Tak!

There is a whole nebula (https://pbase.com/strongmanmike2002/image/164516318/original) named after him in the LMC :thumbsup:

The intricate capillary like filaments in your image are reminiscent of his famous Rhinophyma 'whisky nose' or 'rum blossom' :)

hmmm....seems like an unofficial colloquial name to me.:P


I wonder if my image is enough to trigger trypophobics?

[strongmanmike]

He, he, yes well, almost all descriptive type names of celestial objects are colloquial really, most were coined at some stage by someone, for some reason and then stuck. The story detailed under that image of the Lionel Murphy Nebula, I linked to is (https://adb.anu.edu.au/biography/murphy-lionel-keith-15823) (scroll down) factual though :thumbsup:



Show enough people and I recon you'd get a result :lol:

I must've missed the link to that little biography, that was an interesting read, thanks for sharing (again).


And true enough, I proposed a little colloquialism in the image description/spiel on the image on Astrobin. ;)

[strongmanmike]

YES! Aaaaaarg! I see it...:eyepop: look out, maybe there is a blockhole in it?? :lol:...will it stick though..? So to speak...

[joshman]

Hehe. I kinda of hope that it sticks, and ill do what I can to get it out there.


Either way, I definitely can't unsee it!
