My image was taken with 3 nm Astrodon OIII and H-a filters to enhance the contrast of the filamentary structure. Astrodon Generation 2 RGB filters were used for shorter exposures to bring in proper star colors. The system was guided with a Starlight Express Loadstar guide camera on an Astrodon MonsterMOAG off-axis guider. Data were acquired automatically with CCDAutoPilot4 running Maxim4.62 and PinPointPro. Data were calibrated, registered and pre-processed, including deconvolution in CCDStack. Final processing was done in Photoshop CS5 Extended. Data were taken in the backyard under mag 4.5 skies with the moon up for the narrowband data and RGB before the moon came up.
