Scope: C8 f/3.3 Location: Dos Picos Park, Ramona, CA 1/10/2004 Camera: ToUcam SC3
Exposure: 12 x 15 sec, 12 x 40 sec Luminance Exposure with IR Block. 12 x 20 sec RGB Exposures.
Processing: Captured and stacked in K3CCDTools with IR,R,G,B saved as FITs. IR,RGB masters were co-registered in Astroart. Some Lowpass filtering was applied on the IR channels. The two different IR exposures were combined for Luminance to help reduce star sizes. . LRGB combine were done in Photoshop. Luminance Layering was used. No ears - the exposure was made with RAW mode. Color balancing and final touches in Photoshop.
This was a guided exposure. This is one of those objects with bright stars and surrounding nebulosity - they always seem to be a challenge. In this particular image some refection in the glass interfaces can be seen on the bright stars. This image is a nice example of the advantages to the RAW mode, there was no usual "repair" needed in the nebula region due to the "ears" artifacts common to this type of camera prior to the RAW mode modification. Horizontal FOV is 26'
