Imaging was performed at the Barking Spider Observatory located in Castro Valley, CA. All images were acquired using Equinox Image which controlled an SBIB ST-2000XM as well as a filter wheel and adaptive optics unit. The telescope used was a standard Celestron SCT (280 mm aperture, f/6.3). Generally, five to 10 guided five minute LRGB exposures were obtained, stacked using Nebulosity, and then minimally processed using Nebulosity or Photoshop CS3. In the case of the Horsehead Nebula, eight five minute H-alpha exposures were processed as described above.
