Hi all, just uploaded an image of an object that is very rarely imaged (if ever..) despite being extremely interesting:

Supernova Remnant Puppis A (http://www.glitteringlights.com/Images/Nebulae/i-hkdT9RF)

Puppis A is the remnant of a supernova that exploded about 3,700 years ago the constellation of Puppis. It is superimposed over the signal of the more ancient Vela supernova remnant that occurred 12,000 years ago (but it is 4 times closer than Puppis A), and this is one of the reason why this object is perhaps so much neglected by amateur astronomers.

The expanding shock waves from that explosion are heating up the dust and gas clouds surrounding the supernova, causing them to glow and creating the beautiful red cirrus we see scattered around the center of the image.

The remnant of Puppis A are scattered around the center of my image, yet some of the tail-colored gas and dust in the pictures are from the Vela supernova remnant, so it is difficult to separate completely the two objects in visible light.

Puppis A is one of the most powerful and well-studied X-Ray objects in the sky.

Ha(540m)OIII(540m)L(180m)R(70m)G(80 m)B(60m) composition, with very long exposure in both OIII and Ha to bring as many details as possible on the object.

I strongly suggest to view it at full resolution! Hope you will like this one..

Another beautiful image from Marco, setting the bar higher and higher? ... ;)

Incredible image Marco. Love all the subtle wisps of that blue nebulosity throughout the image. Fantastic stuff!

I have looked up the RA and DEC.

It seems to be around RA 8h23m16" DEC -42deg41m41.4"

Does that seem right?? If so, you might have inspired me to chase this one down and have a go at it, as I can reach that DEC.

Thanks,
Tim

Boy that is sensational Marco. You are very good at finding these unusual off the beaten track objects.

Beautiful image with large and small detail structures. Great colour, smooth back ground too. :thumbsup:

Gee, that's a very interesting and even eclectic looking field Marco with some lovely fine, faint and even fiery details...bit like a lovely Minestrone :D..very nice indeed.

Buon appetito :thumbsup:

Beautiful image Marco!

It doesn't look like an easy target - probably why it isn't image often. I'm glad someone (like you) has a go at these - it's out of my capability.

Another inspiring image Marco, but I think you spilt some pink paint on your photo. :lol: Seriously dude, some really nice details and colour in this one. Great work yet again.

Absolutely stunning Marco. So many intricate details and small objects each of which would make an interesting picture in themselves with a larger scale.

All the superlatives have been used already :) Fantastic image, Marco!

Thank you all for the nice comments and appreciation! For instance Don Goldman just released an higher resolution image of (part of) the area that worth a visit: http://astrodonimaging.com/gallery/puppis-a-2/
Apparently we were imaging the same area at the same time :)

Indeed it is surprising to me that there are very little images on these objects, I hope this will serve others as good suggestion for a different target to aim next fall..

You are right Tim, the object approximate center is at 8h24m and -42d50m even if the right framing depends on your actual focal length and FOV..

Wonderful image of a target right under our noses yet rarely imaged.

There is something about Italians and astro-images :) Oi, Mike... :P

Bella immaginario. Colore Glorioso. Un vero capolavoro di fotoni

Thanks again Tim :)



Thanks Troy, in fact there are lots of these objects out there to "discover", it is part of the journey as well :)



Thanks Kevin



Grazie Leo ;)



I guess it is the kilograms of parmisan cheese and tomato sauce we add to everything we eat Lewis, have an effect on the way we approach astroimaging while we are not sleeping because of heavy digestion :lol:
Kidding apart, thanks for the appreciation mate!

Superb vista. Really cool. :thumbsup:

Very special. Very skillful.

It is such a pity that the two or three very best supernova remnants, like Vela SNR and Cygnus Veil, are far too big to fit into our 36 min arc field of view. Sob.
