A new three-color narrowband version of the North America and Pelican Complex. Both nebulae belong to the same interstellar cloud of ionized hydrogen gas, but they are separated by a ragged lane of interstellar dust that absorbs their light. The North America (NGC7000) and the Pelican Nebula (IC5070) show rich and diverse structures filling the […]
This is the central part of the constellation Cygnus, including Deneb and Sadr as main stars, covering a field of about 13 by 10 degrees. This image focusses on the rich H-alpha nebulosity in this region. In contains some of the famous emission nebulae, e.g. the North America Nebula, the Pelican Nebula, and the Crescent […]
The southern part of the North America Nebula, NGC7000, with a dramatic cloudy ridge also known as the Cygnus Wall – the most active star forming regions in the nebula. This image is composed of Ha, OIII, and SII frames with a total of 22 hours of exposure time. Exposure: HOS, (18,10,16) x 1800sec Date: […]
Now the full three-color narrowband version of the North America and Pelican Complex, following my earlier Ha monochrome version. Both nebulae belong to the same interstellar cloud of ionized hydrogen gas, but they are separated by a ragged lane of interstellar dust that absorbs their light. The North America (NGC7000) and the Pelican Nebula (IC5070) […]
This is the second target for my new wide-field setup, the North America and Pelican Complex. Both belong to the same interstellar cloud of ionized hydrogen gas, but they are separated by a ragged lane of interstellar dust that absorbs their light. The North America (NGC7000) and the Pelican Nebula (IC5070) show a rich and […]
Can you see the pelican? This is Pelican Nebula IC5070 in a tri-color narrowband composite. As with all narrowband composites, these are false colors and the color scheme is largely a matter of taste. Here I use a somewhat conservative and not overly colorful scheme. I am still not completely happy with the post-processing. This […]
