View Full Version here: : Bubbles and Twists - Vela SNR

This is an object I have always wanted to image, years have come and gone and it still remained at the top of my imaging list. I have collected well over the 39.5 hours of data contained within this image.
This is only a very small part of this object and luckily enough the composition is in one of the densest areas. Getting the composition as I wanted did take some time.
I really am intrigued with the bubbles in the field of view and the subtle interaction of the OIII and Ha twists. There are so many twists of gas and gas bubbles it takes quite a while to investigate all the image. To that end I am thinking I might do another section of this object next year and add a panel to this image. Such is my interest now in this object.
Click here (http://paulhaese.net/VelaSNRpart1.html) for the large resolution image.
There is still some noise present, but after the last couple of nights I have come to the conclusion that I would need to double the integration time to eliminate the pesky stuff and that is far too much time used for such little gain.

Hi, Paul. A wonderful image. Incredibly complex, fine, delicate twists and turns.
Can you give Ra/Dec and FOV?
Very best,
Mike

A fabulous image of my favourite part of the Southern Sky. Yes that is the most dense and most interesting area of the Vela SNR.
Superb.
Greg.

What mike said! so complex, and it's really 3D in presence.

The colour balance while quite gaudy is fitting for the image detail and in your face appearance.
Very nice job Paul.

Nicely done Paul. The colour balance is somewhat different than I've seen before but very effective.
Cheers

Magnificent image - the colours are beautiful.

This is really outstanding image. It clearly shows that patience with collecting suffient amount of data leads to great results.

Lovely image, Paul, but as I mentioned elsewhere you really should attach an ICC Profile to the image so that those of us with calibrated screens and colour managed software can see it in the colours you intended :thumbsup:
Cheers,
Rick.

A great looking photo Paul.
Amazing detail that you have highlighted so well with the colours.
Very sharp!

That's a beautiful shot Paul. As Slavomir said, the patience to collect lots of data pays off. And on the subject of collecting lots of data, may I inquire as to how many cloudy or unfavourable nights you get down there in Clayton's Bay? I am assuming not many from the sheer amount of data that is collected for your images...:thumbsup:

Lovely shot Paul. It's an amazing object and the bicolour treatment makes it seem more like a hallucinogenic trip than a DSO. Always make me think of that Asimov story where they become super small and travel through the veins and arteries of the body in a tiny submarine. 39.5 hours!!!!

Thanks all for taking the time to comment. It is much appreciated.
Thanks Greg. Hunting around for the right spot was a bit difficult. Neither the Sky6 or Skyx has an image of the area on file. That made it a bit hit and miss. Only an hour to find the right spot though.
I think narrow band gives the most chance for creating that 3D look. However, enhancing the luminance of an image certainly helps give the appearance of three dimensionality.
Sort of dealers choice on the gaudy, but I get your point Doug. Finding that balance to get an acceptable result is certainly difficult.
Apologies Rick, I have now sorted that out. I keep forgetting each time I save to check that box. You should find the uploaded image has the profile now.
Actually, Clayton does get its fair share of cloudy nights. This imaging run began on 29th of December. It was a run of 15 nights. Some nights I picked up 5 hours and some nights only 1 sub. The boys at Arkaroola have a much better strike rate than I do as that site has a dryer climate and less nights affected by cloud coming off the ocean. SA being the driest State in Australia certainly produces less cloud, though this year has had quite a few cool days brought on by cloud.

Yes that is a problem. I used Rob Gendlers mosaic as a map plus Marcos 300mm image. Also my own widefield images to know where the most dense areas are. You got the right spot. Also the Y shaped section on the lower left side of the Vela is fairly dense as well.
The wisps show up better in an O111 focus image rather than Ha.

Great image Paul.

Ta, Paul. I think that the web site software must be stripping off the profile. Astrobin does it too :mad2:
Cheers,

awesome detail whilst still being delicate.
great work

Thanks Russ and Steven for your comments.
I was mainly wanting to use plate solving to get the exact co-ordinates but as you know jpegs don't contain the same info as a Fit header which has the recorded data. So it was a bit of suck it and see.
I will have to chase around for the other part you are referring about at some point.
That is a real pain. It could also be the irfan view resample software too. Though wysiwig via dream weaver might strip out that data as you say. Always a problem getting the colour one intends for people to view.

I've just spent 10 minutes touring the large version Paul, and it is magnificent. So much interesting detail in there.

Thanks Trevor. There are several spots where the OIII seems to be encasing the Ha gas or each is twisting about each other. Its just incredible to think about that occurring.

Again, a very impressive image, well done Paul.
