Eagle Nebula M16 in Serpens Cauda


Scope: Starmax 127  f/6 Location: Ramona CA   6/27/2003  Camera: ToUcam SC3

Exposure: 16 x 36  sec and 10 x 72 sec IR filter and 10 x 24 sec RGB filters

Processing: Captured aligned and stacked in K3CCDTools  with IR,R,G,B saved as FITs. Luminance was a combination of the 2 IR exposures, the shorter exposure used to desaturate the bright stars. LRGB masters were registered and combined in Astroart. Some Lowpass filtering was applied followed by un-sharp mask on the Luminance frame. LRGB result was saved as a BMP. Background was smoothed in SGBNR as saved as TIF. The result TIF had minor touch up in Photoshop.

This image was taken in Dos Picos park in Ramona. Interestingly enough, I did not get any improved detail (or so I thought during the exposure session) in exposing through a H-Alpha filter. I thought this object would be a good candidate for such an exposure. Horizontal FOV is 22'
