IC 405 Flaming Star Nebula



Scope:  C8 at f/3.1 Location: Tierra Del Sol (SDAA dark site), CA   5 November, 2005  Camera: Artemis285

Exposure: 8 x 360 sec H-Alpha (1x1),  6  x 120 sec Luminance (bin 1x1) with  IR/UV Block plus Green Filter 8 x 72 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. Central gradient removal in Astroart. Channels were co-registered in Astroart.  In Photoshop, the H-Alpha exposure was the main exposure for the luminance construction - the  120 sec Luminance was used for star field depth and detail. Curves and Levels were applied in Photoshop to optimize object appearance.  Final LRGB combine was done in Photoshop using Luminance Layering (or LLRGB).  Some HA data was combined with red channel to deepen the red of the nebula somewhat. Color balancing and final touches were done in Photoshop.  Selective layer sharpening was performed on prominent nebula features. Final Image size is approximately 1392x1040.

All exposures in this image were guided; North is up in this image. IC 405 is an emission / reflection object in Auriga. The bright star in the lower right is  the suspected  illumination / energy source for the nebula. This image replaces an earlier image that can be seen in the Archives here. The Horizontal FOV is 55'.

Image center is located approximately - Equatorial 2000: RA: 05h 16m 29s Dec: +3421'22"
