IC1848 / LBN672 in Cassiopeia - The "Baby" Nebula



Scope: Megrez II  f/3.2 Location: Del Mar, CA   29 September 2005  Camera: Artemis285

Exposure: 10 x 300 sec H-Alpha (1x1),  8 x 60 sec RGB Exposures (2x2).

Processing: Images were captured  with Artemis Capture (as FITs).  Aligned/stacked in Registax 3 and saved as FITS. Luminance,  H-Alpha,   and Color channels were scaled and rough color balanced in Astroart. Channels were co-registered in Astroart.  The H-Alpha exposure was the main exposure for the luminance construction. Some star repair was required on the luminance channel since a heavy stretch caused some artifacts  and brought out coma on the edge stars. Due to the short RGB times, the HA exposure (with stars removed) was used as a "lighten" combine in the red channel .  Final LRGB combine was done in Photoshop using Luminance Layering (or LLRGB).  Color balancing and final touches were done in Photoshop.  SGBNR was used to smooth background noise on the final result.  Final Image size is approximately 1392x1040.

All exposures in this image were guided; North is up in this 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. This image replaces and earlier image in the archives here. The Horizontal FOV is 122'.

Image center is located approximately - Equatorial 2000: RA: 02h 54m 45s Dec: +6022'04"
