Scope: C8 f/5; Location: Del Mar, CA; 12 May. 2004; Camera: ToUcam SC3
Exposure: 20 x 10 sec Luminance exposures with IR Block Filter; 10 x 50 sec and 16 x 15 sec with Orion SkyGlo filter, 12 x 24 sec RGB
Processing: Images were captured in K3CCDTools. Aligned/stacked in Registax and saved as FITS. Luminance and Color channels were scaled and rough color balanced in Astroart. Channels were co-registered in Astroart. The 50 sec SkyGlo filter exposure was used as the base Luminance channel. The shorter Luminance exposures were normal combined with core mask to desaturate and sharpen the core in the Luminance channel. Luminance and Color FITS were combined in Photoshop with Luminance Layering. Color balancing and final touches in Photoshop. SGBNR was used to smooth background noise on the luminance channel and the final result. Resized to approximately 800x600.
image was guided. The different exposure levels helped to desaturate the core
and improve star resolution on the core stars. This
