Deep image of Vela SNR

Here's an image I did which shows part of the supernova remnant in Vela.

The image is a little pushed, a little noisy, but you can certainly see the supernova remnants in reasonably good detail.

I might also do a more suttle/natural appearing version of this image....

96-minute exposure with Houghys cooled Canon 350DSLR on my WO Megrez 110mm refractor.

you can find a better look at the image here http://www.skylab.com.au/pmsa/VelaSuperNovaRemnant.html

yes a trifle noisy as you say but impressive amount of detail...add more exposure maybe to combat the noise?

WOW!
Superb detail.

Here I go again, but can any one else see "things" in this image?
At the very top, just to the right of centre the nebulosity has formed into a skull. To the left of it is a piggy/farm animal sort of shape. The more I look the more I see.

I guess it's no more weird than seeing the Owl Eyes in Omega Centauri.

Processing aside, this is a rather spectacular image Paul. The tendrils look like the Terra forming vines made from Human juice that the martians sprayed in Spielbergs War of The Worlds remake with Tom Cruise.

Is this the image version you submitted to the DM awards?

Thanks everyone for taking a look. I should have mentioned this image is almost 2-degrees wide.. so it covers a fair area of the sky.

DM Awards? No.. don't think my images qualify for stuff like that ( of course you could loan me your FLI mega-ccd tripled cooled quad-overhead cam turbo charged CCD camera - then I'd be able to enter... ).

cheers

Amazing image Paul, I loved the intricate twists and turns of the nebulosity.

Wonderful work indeed.

C'mon sure they are, with a bit of noise work and perhaps some colour fiddling, to me that image has that X-factor that many images lack..?

You sell your images short ma friend

I agree with Mike it is a hot image.

One way to reducer the noise is to use the blur tool in Photoshop if you have it.

Simply select the blur tool and then rub it on the noisy areas. You can adjust for how hard or soft the effect will be.

Another way is to lasoo the noisy areas using the control key to add new lasooed areas. Feather it 10 - 20 pixels and then use the gaussian blur filter to smooth it out to your taste.

You can refine this a bit by selecting the red, blue and green channels individually one at a time and rub the blur tool on those channels noisy areas. Often it is one colour channel that is noisier than the others so this way you don't blur the other channels where the data is OK.

Some people use Noise Ninja but i have never used it.

Greg.

A very simple way of reducing noise without sacrificing detail as is always the case when using the blur tool is the following. (You don't even have to select the noisy regions of the image.)

http://users.westconnect.com.au/~sjastro/Tutorial/colour.html

The procedure is found under Reducing Colour Noise.

Regards

Steven
