CLICK HERE FOR HIGH RESOLUTION - (2700 x 1800) Scope: Megrez II at f/5.4; Location: Dos Picos Park, Ramona, CA; 5 Septembert, 2008; Camera: Canon XT 350D (Baader ACF modified) Exposure: 8 x 12 min Ha (13nmAstronomik EOS clip), 10 x 5 min (no filters) all ISO 800, 5 Darks each, no Flats Processing: Images were captured with DSLR Focus and saved as RAW file format. Images were decoded and dark corrected in IRIS. Images were aligned and stacked in IRIS with Sigma Median. Dark point equalization and rough color balance were done in IRIS. Color saturation, and gamma adjustments also done in Iris. Image was saved as Tiff. Luminance construction consisted of the Ha exposure stack lightened by the unfiltered exposure stack. Both were done in RGB converted to grayscale in Photoshop. LRGB Combine was done in Photoshop using the unfiltered exposure for color and the luminance construction as the luminosity layer. A color adjustment was done for low signal intensity level by lightening red and blue channels (100% and 25% respectively). Final stretching and touch up was done in PhotoShop. Final Image size is approximately 2700 x 1800. North is up in this image. The image was taken with medium light pollution conditions. This is a guided image. The IC 1848 / LBN 672 complex is an emission nebula located in the Southeastern corner of the constellation of Cassiopeia. It is just East of the somewhat better known IC1805 / IC1795 complex. This nebula is sometimes called the "Baby" Nebula or "Fetus" Nebula due to its shape which appears as the shape of a baby or fetus on its back. IC 1848 is an emission nebula with a dominate Hydrogen Alpha emission line.. Horizontal FOV is 135' Object Center is approximately - Equatorial 2000: RA: 02h 55m 54s Dec: +60°23'35" Back to DSLR Images
