From: Jean-Christophe Meriaux Date: 6/12/2010 Location: San Bruno, CA – near the SFO airport… Magnitude 3 stars are seen at best with the naked eye. Telescope: C9.25 at F/D 6.3 with Focal reducer / corrector Mount: Atlas Mount with Orion Short tube 80mm and Star Shoot autoguider Camera: QHY8 – with Astronomic CLS CCD Filter. 17 exposures of 420 seconds bin 2×2 – processed with MaximDL5. Dark, Flat field, and biais images were used. Post processing with Photoshop CS4, Noise Ninja, and Focus Magic. I use layers and careful processing to make sure details in the center of the Nebulae are not too over-saturated / lost. It is one of the first picture I am processing with Noise Ninja, and I like all the controls it provides compared to NeatImage (another noise reduction program).
