Sh2-190 - The Heart Nebula This is an emission nebula in Cassiopeia. It was discovered by William Herschel in 1787. There is a small open cluster near the center which is responsible for heating the surrounding gas enough for it to glow. The predominate gasses are sulphur and oxygen. It is roughly 7500 light-years away. It is also known as the Running Dog Nebula. Image processed by Ron Yelton, original data from Telescope Live |
Sh2-190 - The Heart Nebula WilliHere's another version of the image to the left. The first version was done in SHO. This image was done in OHS. What I like about processing an image in different ways is that completely different details always emerge in each one. Image processed by Ron Yelton, original data from Telescope Live |
Sh2-199 - The Soul Nebula The Soul Nebula is an emission nebula located in the constellation Cassiopeia. There are several small open clusters located in the center area. Its distance is roughly 7500 light-years. This image was processed in HSO. Image processed by Ron Yelton, original data from Telescope Live |

BBWo56 This is an emission nebula in the constellation Puppis. Not much information s available for this object other than it is an emission nebula, rich in Hydrogen Alpha. Image processed by Ron Yelton, original data from Telescope Live |
Sh2-274 - The Medusa Nebula This very old planetary nebula was first observed by George Abell of UCLA in 1955. it's about 1500 light-years away and is in the constellation Gemini. Image processed by Ron Yelton, original data from Telescope Live |
Messier 6 - The Butterfly Nebula Surrounded by beautiful nebulosity, this central open cluster appears to resemble a butterfly. Thus the name. it is thought that the 2nd century astronomer, Ptolemy first observed this cluster naked-eye. It has since been observed by a number of early astronomers and was eventually added to Charles Messier's list. It lies about 1600 light-years away in the constellation Scorpius.

Messier 6 - The Butterfly Nebula This image was taken with the same telescope (but with a different camera) as the image in the row above. It has been cropped and blown up a bit. I decided to try processing it in the same palette (OHS), but accentuating the colors differently. Image processed by Ron Yelton, original data from Telescope Live |
CED 116 (GUM 39) This is an emission nebula in the constellation Centaurus. It is commonly associated with the Running Chicken Nebula as the head of the chicken. Image processed by Ron Yelton, original data from Telescope Live |
Messier 42 Widefield (OHS)
- The Great
Orion Nebula M42, in the constellation Orion, is a diffuse nebula. It is so bright that it is mistaken as the middle "star" in Orion's sword. It is also the closest star-making region closest to Earth (1300 light-years). In this image it is the bright orange area. Just to the left of the Orion Nebula is the Running Man Nebula (light blue). Down in the lower left is the Horsehead and Flame Nebulae. These three objects are probably the most photographed objects in the night sky.

Orion Nebula This is another version of the Orion Nebula as in the row above. This has all of the stars removed. Click on the image to see a larger version. As I was processing this one it struck me that it has kind of an abstract art look to it. Image processed by Ron Yelton, original data from Telescope Live |
NGC 2014
NGC 2014 is an emission nebula located in the constellation Dorado. It also surrounds an open cluster, although there are a number of open clusters located throughout this image. Its distance from Earth is about 163.000 light-years. Image processed by Ron Yelton, original data from Telescope Live |
