PhotographerRod PommierLocationPommier Observatory, Portland, OR, USADate2011-07/29 through 2011-08-02.EquipmentTelescope/mount: Celestron Compustar C14 with 0.75x focal reducer (f/8). Camera: SBIG STL 11000M with Baader Planetarium LRGB filters. Exposures: Exposures: LRGB=235:130:130:130 minutes=10:hours:25minutes total exposure. Self-guided. Calibrated with bias, dark, flat field frames.DescriptionThe Crescent Nebula (NGC 6888, Caldwell 27, Sharpless 105) is an emission nebula that lies 5000 light-years from Earth in a crowded region of the Cygnus Milky Way. The nebula arises from the bright star near the center of the image, which is the Wolf-Rayet star WR 136 (HD192163). Wolf-Rayet stars are massive, extremely hot stars which throw off tremendous amounts of mass in the form of stellar winds at high velocities near the end of their lives. The nebula forms because this material is colliding with slower moving stellar winds ejected 400,000 years earlier during the stars red giant phase, creating a shock wave, high temperatures, and spectral emission lines. |

The surrounding area also contains blue reflection nebula and dark absorption nebula which gives the image a broad range of color and depth. |

PhotographerBernard MillerLocationRancho Hidalgo, NMDateSeptember 20, 2011EquipmentTelescope: TEC-140 (F7) Camera: SBIG ST-8300M Mount: AP900 GTO Ha: 8x15 minutes (unbinned) Luminance: 12x10 minutes (unbinned) Red: 6x10 minutes (binned 2x2) Green: 6x10 minutes (binned 2x2) Blue: 6x10 minutes (binned 2x2)DescriptionThis is an image of SH2-155, the Cave Nebula. It is a dim and very diffuse nebula within a larger nebula complex containing emission, reflection, and dark nebulosity. It is about 2400 light years away in the constellation Cepheus. The nebula gets its name from the dark lane at the eastern side abutting the brightest curve of emission nebulosity which gives the appearance of a deep cave when seen through a telescope visually. |
