It's time to get this back on the 1st page.
This is different than anything I've posted and something I've been working on for a while. I'm including a brief overview I posted on my FB page(@NoMondaysPhoto for fellow members of the evil cult). The colors are similar to those in many Hubble images.
NGC 7000, aka the North America Nebula in the constellation Cygnus, is an emission nebula covering an area in the sky over four times the size of the moon.
I captured this image using a technique called narrow band imaging which is why it looks different that what I've posted in the past. Narrow band images are captured using special filters, each passing only a very narrow, specific portion of the spectrum emitted when a certain gas is ionized by a nearby star.
After the images have been captured, data from each filter is assigned to a color channel and blended with software.
I combined about 4.5 hours of exposures from Sulfur, Hydrogen, and Oxygen emissions to create this image.
