Scope: C8 f/2.8; Location:
Dos Picos Park, Ramona, CA; 6 Nov. 2004 (color) Blair Valley, Anza
Borrego Desert, CA 9 Oct. 2004 (Luminance); Camera: ToUcam SC3
Exposure: 16 x 72 sec and 16 x 20 sec Luminance exposures with IR Block Filter;
14 x 32 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. Star sizes were reduced somewhat by combining (with mask) the
shorter 20 sec exposure with that of the 72 sec Luminance exposure. Luminance and Color FITS were combined in Photoshop with Luminance Layering.
Color balancing and final touches in Photoshop. SGBNR (PixInsight LE) was used to smooth background noise on the luminance channel and the final result. Resized to approximately
This image was a guided image. North is to the right in this image. Data for
this image was taken over two nights separated by nearly a month. Conditions the
first night allowed for Luminance data but then deteriorated and color data
could not be taken - I finally got the color data early November. Horizontal FOV is about 30'
