NGC 6888 - The Crescent Nebula
Details
Date Taken: 07/19/2011
Photographer: Doug H.
Location: Temecula, CA
Telescope: Orion ED80T CF 80mm triplet apochromatic refractor
Mount: Orion Atlas EQ-G
Camera: Parsec 8300M Monochrome Astronomical Imaging Camera
Exposure: 8 - Ha (30 Minute Frames) 1st night, 11-OIII (30 Minute Frames) 2nd Night
Other Equipment Used: Orion Nautilus 2" Filter Wheel, Orion 2" Ha Filter, Orion 2" OIII Filter, Orion Accu-Focus (Mod), Orion Rockstable Mount Pads,Orion Starshoot autoguider, Orion 80MM F/11.4 Guide Scope, Orion Ultrascopic 5mm Illuminated Eyepiece (Used for alignment), Orion Dew Zapper System, Televue TRF-2008
Notes: Combined image of two types of processing. The Red Crescent Nebula was developed by creating a synthetic green and the Ha nebula was created using a Selective Color technique. Combining both images into one I felt looked the best. The OIII stack wasn't tracking very well, the second night I selected a different guide star and it resulted in football stars.
