| Photos of The Week - Sept-Oct, 2013 2x2 panel Inserts - Trius 814 and H694 Camera |
| 2h 30m Ha stack - Trius 814 |
| The Wizard Nebula - NGC 7380 NGC 7380 (also known as the Wizard Nebula) is an open cluster discovered by Caroline Herschel in 1787. William Herschel included his sister's discovery in his catalog, and labelled it H VIII.77. It is also known as 142 in the 1959 Sharpless catalog (Sh2-142). This reasonably large nebula is located in Cepheus. 9 hours of simultaneous narrow band Imaging - Hubble Palette. Presented in a 'Micro-Macro-Mosaic' as I am calling it using the following equipment: - Tak FSQ-106 reduced to f3.6 and mounted with a SX Trius 814 mono camera - 'detail' insertion image. Astrodon 5nm narrowband filters - 8.5 hours total - 20 minute exposures - EF200 Canon lens mounted on a SXVR-H694 camera - wide field image. Baader narrowband 2" mounted filters - 9 hours total - 20 minute exposures. Capture and Processing: Losmandy G11 mount. Nebulosity and PHD for capture. DSS for registration and calibration. PixInsight and PS4 for Processing. |

DWB-111 - The Propeller Nebula is an emission nebula in the constellation Cygnus. The Propeller Nebula is actually part of a much larger nebular complex that includes numerous objects. Little is known about this object or the source of excitation that caused its shape. 10.5 hours of simultaneous narrow band Imaging - Hubble Palette. Presented in a 'Micro-Macro-Mosaic' as I am calling it using the following equipment: - Tak FSQ-106 reduced to f3.6 and mounted with a SX Trius 814 mono camera - 'detail' insertion image. Astrodon 5nm narrowband filters - 10.5 hours total - 20 min. exposures - EF200 Canon lens mounted on a SXVR-H694 camera - wide field image. Baader narrowband 2" mounted filters - 7 hours, 40 min total - 20 minute exposures. Capture and Processing: Losmandy G11 mount. Nebulosity and PHD for capture. DSS for registration and calibration. PixInsight and PS4 for Processing. |

| The California Nebula - Narrow Band Hubble Palette 2-Panel Mosaic The California Nebula (NGC 1499) is an emission nebula located in the constellation Perseus. It is so named because it appears to resemble the outline of the US State of California on long exposure photographs. It is almost 2.5° long on the sky and, because of its very low surface brightness, it is extremely difficult to observe visually. Imaged with the following equipment: - Tak FSQ-106 reduced with a Trius 814 mono camera - two frame 'detail' insertion mosaic - EF200 Canon lens with a SXVR-H694 camera - two frame wide field mosaic. The below image is two camera, two panel mosaic presented in a modified Hubble Palette. It consists of a wider field image totalling 18 hours in two panels using the EF200 Canon lens and the SXVR-H694 CCD. Inserted into that is the detail from a narrower field of view imaged over 15 hours using a Tak FSQ-106 with a reducer and a SX-Trius 814 camera. Total hours of data total 33. Elapsed imaging time was 18 hours using simultaneous data capture through the two imaging trains mounted on a Losmandy G-11. |

| Other, low exposure time images for the month: |
| Crescent Nebula - Hubble Palette - H694 camera - C11 Edge HD scope @ f7 with SX Active Optics unit. |
| Sun - H694 Camera - Tak 106 reduced - Baader filter film |
| M33 Core - C11 Telescope @ f7 - H694 Camera - SX Active Optics Unit - RGB + Ha |
| Wide-FIeld Milky Way - St. George's Island - Canon 60Da and Polarie portable mount |
| Color and Grey Scale 'Gas Extraction' Action I wrote in PS produces these images. They are useful for added luminance or reducing the stars in the final image using Layers and the Opacity slider in PhotoShop. |
