Beautiful shot. What kind of equipment did you use for this.?
This is a mosaic of 8 panels, each of which is comprised of at least 15 hours of imaging time, taken through clear, red, green and blue filters. All panels were LRGB composites, where the luminance layer typically consisted of a blend of the clear-filtered and blue-filtered data. All individual images were 15-minute exposures through Astrodon type 1 filters. All images unbinned.
Equipment: Takahashi FSQ106 quadruplet fluorite f/5 apochromatic refractor, SBIG STL11000M camera (cooled to -15C) with internal color filter wheel (Astrodon Type 1 filter set), on a Bisque Paramount ME German Equatorial Mount.
Image Acquisition/Camera Control: Maxim DL, controlled with ACP, working in concert with TheSky v6.
Processing: All images calibrated (darks and dawn flats), aligned, combined and deconvolved (luminance data only) in CCDStack. Color combine in Photoshop. Finish work (curves and levels, adjustment of saturation and contrast) was done in Photoshop CS5.
Location: Data acquired remotely from Fair Dinkum Skies, Moorook, South Australia.
