Cygnus Bubble HaRGB

PN G75.5+1.7 - "Soap Bubble" Nebula in Cygnus	HaRGB
HaRGB Cropped Field of View - Full Resolution (1.15 arc-second / pixed)
Description This "Soap Bubble " spherical shape planetary nebula in the Cygnus region was first recognized on July 6, 2008 by Dave Jurasevich. It has since been designated as PN G75.5+1.7. This nebula is approximately 5 light-years across at a distance of approximatley 4000 light-years. The above image is the result of 8 hours of H-Alpha and 5 hours of RGB imaging aimed at capturing the RGB and H-Alpha emission light of this nebula. H-Alpha data was added to the luminance channel to make the Bubble visible as it is extremely faint and has very little dynamic range.
Imaging Session Date: August 13 & 14 2009 (H-Alpha) and August 24 & 26 (RGB) 2009 Target Coordinates (J2000) : RA = 20h 15m 22s, Dec = +38:02:58 (J2000) Exposure: H-Alpha: 24 frames x 20 minutes/frame unbinned at -15C, RGB: 20 frames x 5 minutes/frame binned 2x2 for each channel at -15C Camera: SBIG ST-10XME with AstroDon H-Alpha 6nm and RGB filters Equipment: Takahashi FS-152 f/8 on Takahashi NJP mount Guiding: external guidescope Takahashi FS-60C and Meade DSI Pro Observatory control and automation software: CCD Commander V1.5.34, Maxim DL V4.56, FocusMax 3.4.1 Location: Theberge Remote Observatory, Robosky, Orangeville, Ontario
