NGC7000 Wide Angle in HST
« on: 2013 November 19 17:40:08 »
Hi,

Sorry, I know this is a cliché and I am very late in the season to come up with a North America render, but I just finish it and I want to share it.

The image is a 2 tile mosaic taken with the FS60 and SBIG STF8300, I tried to frame the nebula a little bit different than the canonical way.

The image can be found here:

More details about the image and a couple of 'alternative' renders here:

If you read spanish you can read a small review of the image and equipment here:

http://mtanous.wordpress.com/2013/11/13/la-nebulosa-de-norte-america/

The image details are:

* Telescope Takahashi FS60 @ 254 FL
* Orion Atlas Mount
* Camera: SBIG STF8300
* Guided with SX OAG
* Guider camera QHY5L-2
* Filters Astrodon 5nm
* 2 Panel Mosaic
* 25x30m Ha @ 1×1 per panel
* 1x30m OIII @4×4 per panel
* 1x30m SII @4×4 per panel

Thanks!

Amazing image. I love the HST classic palette.

Interesting how do you enhace the colors with only that short shots.

Nice image!

Out of curiousity, how did you mix your colors.  I use SII*0.8+Ha*0.2 for my Red, then a straight Ha for green and a straight OII from Blue.

Best,

Jim
Really, are clear skies, low wind and no moon that much to ask for?

Thanks for your kind comment!

The color was there, but it was very noisy. You can apply very aggressive noise reduction filters to the color image before substituting the L channel without loosing (many) details.

Cheers,

Jose

Hi Jim,

I blend all the channels in the same proportion, however each channel is arbitrary stretched before mixing it. After the initial mix I tweak the green channel with the histogram tool, I remove all the green cast using this tool. Then I move forward and replace the L channel.

Cheers,

Jose

That's a really nice image. I like the colors, I like the background level, and I think you did a great job with the stars. It's very enjoyable to look at!

This image is just glorious, well done! Something for me to shoot for, I thought I was down with NGC 7K. This inspires me!

Josh,

This a very rewarding and generous object, specially for narrowband setups. Next year I will try to shoot the north america wall.

Cheers,

Jose

Hi John,

Thanks for your comment. I am very happy with the image, it turned out nice despite having very few S2 and O3 data!

Cheers,

Jose
