Remnant 7:15 hours

gregbradley · #1 15-01-2009, 09:19 AM

The Vela Supernova Remnant RA 8:35 Dec 45:45 (in between Suhail and Regor) look for the 4 star asterism and the little group of stars in the shape of a 7 to orient the view.

This took a long time to process. I've been wanting to image this area again after imaging it a lot last year with an FSQ.

This is a huge area of nebulosity.

You can see what appears to be the centre of the explosion with concentric rings going out and a blast of hydrogen gas up the top part.
It must have been one huge explosion.

It is HaO111LRGB 35 160 60 60 60 for a total of 7:15 hours.

Tak BRC250, Apogee U16M camera, Baader filters.

From my dark site in NSW.

Wow. Beautiful Greg. How do handle the Ha & OIII with the LRGB?

Stunning work Greg. Beautiful.

Lovely image Greg - Well done!

7+ hours is a long exposure for you and it paid off I think. Good colour balance, smooth and detailed. Love the overall impact & delicate beauty.

Cheers, Marcus

Now that`s a visual treat for my eye`s....bloody beautiful!
What is the field of view in this image Greg?
cheers Gary

Top shelf Greg!
Beautiful field of view taking in a massive area of this interesting remnant.

Yes how many arc mins WxH are we looking at here?

I like the way you've blended the narrow band data to the rgb.
I guess you assigned the OIII filter to... Blue..

Very nice indeed.

Excellent stuff

All the best
Rich

Thanks Chris, Werner, Marcus, Gary, Rich , Trevor and Craig.

The FOV is large but I am not sure how many arc seconds it represents.
I have an FSQ image of the same area and it does take in quite a bit more.

I blended the Ha and O111 this way:

Ha assigned to red channel, screen one duplicate layer to saturation one duplicate layer to luminosity

O111 same way except 2 lots of layers, one to blue and one to green (O111 is halfway between blue and green and should be teal green as the final colour) but only 1 luminosity layer which pulls down the star sizes a bit to match the narrowband and accentuates the nebula a small amount as well (easily overdone and it washes out the RGB colours).

So that makes 12 layers in total.

Greg.

Gee whiz, thanks Mike.

I think long exposure time always pays off.

that is,

dont no, just awesome

what a fine effort.

Hey Greg, is it possible to post the FSQ image you did last year for comparison and the wider FOV?

bert (Brett) · #14 15-01-2009, 04:51 PM

That is one of THE most interesting image I have seen on this site, Aesthetically too. Sensational image.

Wow

Speechless...

Framing's great, unreal colors. Wow!

Bassnut (Fred) · #16 15-01-2009, 05:06 PM

Excellent image Greg, top work, some very fine detail there, and I havent seen an image of that part Vela before. A supprise pleasure to view.

leon · #17 15-01-2009, 05:08 PM

Gee's Bert I have seen plenty of top images on this site over the last year or two. agreed, this one is excellent, but so are plenty of others.

Leon

bert (Brett) · #18 15-01-2009, 05:17 PM

Leon,

What can I say, I'm a sucker for an explosion!

Lovely work Greg. Pleased you picked up the hard drive and showing us all your work again. Well done.

strongmanmike (Michael) · #20 15-01-2009, 05:49 PM

Fantastic bit of the complex you have captured there Greg, lovely.

Very interesting processing to highlight the OIII too, cool, reminds me of the Semens comples in Taurus.

At the size you have displayed it at (just 1200 X 1200) it does look great but then so do most images at that size

, what's that.. a mere 40% of full size?...Come'on man, show us what that big chip and fast F5 were bought for! Love to see a bigger version to pan around and have a good look.

Mike
