  • NGC7822
The color palette is ordered by atomic weight with Ha = red, OIII = orange, NII = green with a hint of blue and SII = blue. White balance was set where Ha, NII and SII reached their maximal values though, of course, Ha is by far the strongest signal.

TEC140 at f/7 plus an FLI ML16803 camera. Astrodon 3nm narrowband filters.
Ha = 8 x 1500 secs
OIII, NII & SII = 18 x 1500 secs
R, G & B = 8 x 200 secs

WeBo 1
Planetary Nebula in Cassiopeia (The small blue oval in quadrant below left)
The small, OIII rich planetary nebula WeBo 1 (PN G135.6+01.0), is an elongated blue oval near the "V" of the heart nebula.
Visibility is greatly enhanced by the OIII filter. This has been called a Barium Star surrounded by a young planetary nebula.
Discovered by Webbink and Bond, It is morphologically extremely similar to SuWt 2, in being an almost mathematically perfect ellipse. Recent observations at KPNO reveal that its central star is also a close binary, with a sinusoidal light curve and a period of approximately 5 days.

NGC 6902 / NGC 6902B / IC 4946 - Galaxy Group in Sagittarius
http://www.rolfolsenastrophotography.com
Copyright: Rolf Wahl Olsen Link to large image

In the far south-eastern corner of Sagittarius, a constellation otherwise known for its spectacular highlights near the crowded Milky Way centre, lies the very rarely imaged galaxy NGC 6902 and a couple of its neighbours. Despite its beautiful and elegant appearance there is very little information about this galaxy to be found anywhere.
It contains a bright central ring and possibly also an elusive inner bar. The spiral arms are quite faint despite almost 17 hours of exposure, which is indicative of a rather weak population of O type stars. The arms also have a knotted appearance, perhaps due to the presence of brighter HII regions located within them.
The galaxy lies approximately 33 million light years away and was discovered by John Herschel.
A number of other galaxies can be seen scattered across the field of view, including the smaller face-on spiral NGC 6902B to the upper left. At the top of the frame lies edge-on galaxy IC 4649 with some traces of obscuring dust and a hint of a bar structure surrounding its core.
And far in the background countless distant galaxy groupings can be seen as small fuzzy yellowish dots throughout the image.

RS Puppis
http://www.flickr.com/photos/stephen63/ ... otostream/
RS Puppis (or RS Pup) is a Cepheid variable star in the constellation of Puppis.
Because it is located in a large nebula, astronomers using the ESO’s New Technology Telescope at La Silla Observatory, Chile have been able to measure its distance by strictly geometric analysis of light echos from particles in the nebula, determining it to be 6500 ± 90 light years from Earth, the most accurate measurement achieved for any Cepheid as of early 2008-Wiki

NGC 2070 (30 Doradus, The Tarantula Nebula) in Dorado

http://www.irida-observatory.org

Copyright: [url=mailto://info@irida-observatory.org]Velimir Popov, Emil Ivanov[/url]

The Tarantula Nebula (also known as 30 Doradus, or NGC 2070) is an H II region in the Large Magellanic Cloud (LMC). The Tarantula Nebula has an apparent magnitude of 8. Considering its distance of about 49 kpc (160 000 light years), this is an extremely luminous non-stellar object. Its luminosity is so great that if it were as close to Earth as the Orion Nebula, the Tarantula Nebula would cast shadows. In fact, it is the most active starburst region known in the Local Group of galaxies. It is also the largest such region in the Local Group with an estimated diameter of 200 pc. The nebula resides on the leading edge of the LMC, where ram pressure stripping, and the compression of the interstellar medium likely resulting from this, is at a maximum. At its core lies the compact star cluster R136 (approximate diameter 35 light years) that produces most of the energy that makes the nebula visible. The estimated mass of the cluster is 450 000 solar masses, suggesting it will likely become a globular cluster in the future.

The images was taken in Namibia on May 2013 during our Southern Sky expedition.

Wow it's rare to see a closeup of this planetary nebula that was discovered in 1996! It is visible in many widefields of the Heart Nebula.

Amazing image of an equally amazing galaxy! I don't know how there was never an AAO image of this one. Sagittarius has everything, it is home to cometary globules, a Wolf Rayet nebula, a few supernova remnants as well as ultra obscure globular clusters. More to it then the common stuff.

That is an excellent image of a very strange nebula, it also has lots of OIII emission.
