Yes I used a technique very similar to that.
Cool! Nice result. I'll have to try that.

I took the image using H-alpha, SII and OIII filters and it's combined using the Hubble Palette.
Very nice image. But I'm still confused:
Wouldn't the Hubble Palette (Ha = green) make this picture much more green?

However you did it, I like the effect!

Today's color palette is heavy on yellow. I'm wondering what that is, but I didn't see the palette mentioned in the description (only colors of stars).

PS: Thanks again for placing hover-tags inside the picture :)
It may be worth mentioning the hover functionality whenever present; casual users may not know to look for them.

Many interesting photos with today's APOD; I especially liked the Orion in Oxygen, Hydrogen, and Sulfur! Very neat picture of the Flame Nebula! :D The Orion Constellation shows up beautiful on the partial galactic 8-) map! APOD showed a kitty again today, but I left kitty out!

Nice image! What I particularly like about it is the fact that it really brings out the "molecular stream"(?) from Auriga to Monoceros, from the Flaming Star Nebula to Sharpless 284.

The full size image is glorious!

Image From Auriga to Orion

Explanation: What's up in the sky from Auriga to Orion? Many of the famous stars and nebulas in this region were captured on 34 separate images, taking over 430 hours of exposure, and digitally combined to reveal the featured image. Starting on the far upper left, toward the constellation of Auriga (the Chariot driver), is the picturesque Flaming Star Nebula (IC 405). Continuing down along the bright arc of our Milky Way Galaxy, from left to right crossing the constellations of the Twins and the Bull, notable appearing nebulas include the Tadpole, Simeis 147, Monkey Head, Jellyfish, Cone and Rosette nebulas. In the upper right quadrant of the image, toward the constellation of Orion (the hunter), you can see Sh2-264, the half-circle of Barnard's Loop, and the Horsehead and Orion nebulas. Famous stars in and around Orion include, from left to right, orange Betelgeuse (just right of the image center), blue Bellatrix (just above it), the Orion belt stars of Mintaka, Alnilam, and Alnitak, while bright Rigel appears on the far upper right. This stretch of sky won't be remaining up in the night very long -- it will be setting continually earlier in the evening as mid-year approaches.
