12 panel Milky Way mosaic finally finished
It took almost all summer, but the project is now complete. This image shows the Milky Way hydrogen clouds in Cygnus from the propeller nebula at left to the Tulip nebula at top right. In between is the crescent nebula and the bright emission clouds surrounding the star Sadr.
http://www.buytelescopes.com/content...milky-way.jpeg The image consists of 12 panels, each panel is composed of 8 to 16 individual 15 minute exposures. Taken in narrow band Hydrogen-alpha light with a 5" refractor at F4.7. Uncanarrowband |

You can see why starlight from that vicinity is so attenuated if beyond the gas clouds. |

Taken in narrow band Hydrogen-alpha light with a 5" refractor at F4.7. Uncanarrowband Thanks so much for sharing. You are all quite welcome. Narrow band imaging is all I can do here at my location now. We have had a lot of construction around this area and the light pollution has increased to the extent that only a few of the brightest stars are now visible. Narrow band imaging is limited to clouds of hydrogen, oxygen, nitrogen and sulphur which glow due to excitation from UV light from nearby stars. In the Milky Way there are plenty of stars to provide this excitation energy. The following image is a closeup of the Propeller nebula, designation DWB111, which is near the left center part of the mosaic. This image is in color, using the Hubble Palette. Sulphur is mapped to red, hydrogen light is mapped to green and oxygen light is mapped to blue. The yellow areas are primarily hydrogen clouds with some sulphur. http://www.buytelescopes.com/content...la-dwb111.jpeg UncaNarrowband |

I have learned to stop worrying and love the H-alpha for the same reason you have. -- I agree with almost everything that you have said and almost everything that you will say in your entire life. usenet *at* davidillig dawt cawm |
