Scope: Megrez II f/2.6 Location: Blair Valley, Anza Borrego Desert, CA; 9 Oct. 2004 Camera: ToUcam SC3
Exposure: 16 x 32 sec and 16 x 10 sec Luminance exposures with Baader IR Block Filter, 6 x 240 sec H-Alpha exposure; 14 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 Nebulosity was extracted
from HA and then combined with the 32 sec IR for Luminance in Photoshop -
The 10 sec IR was used to minimize some star bloating. Extracted nebula from HA was used to provide false
color for the nebula in the Red channel. 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 Luminance channel
as well as the final result. Image was resized to 800 x 600.
This image was taken at a dark site with minimal light pollution. This is a guided image. It
was somewhat windy this night, but tracking and guiding held reasonably well for
this wide field. A close up of the bright central area is shown below. The close
up is a separate exposure and not simply a crop and resample .
Horizontal FOV is about 80'

Scope: C8 f/2.8 Location: Del Mar, CA; 13 Oct. 2004 Camera: ToUcam SC3
Exposure: 20 x 12 sec and 24 x 3 sec Luminance exposures with Baader IR Block Filter, 6 x 240 sec H-Alpha exposure; 12 x 12 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 Nebulosity was extracted from HA
and then combined with the 12 sec IR for Luminance in Photoshop - The 3
sec IR was used to minimize some star bloating. Extracted nebula from HA was
used to provide a small amount of false color for the nebula
in the Red channel. 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 Luminance channel as well as
the final result. Image was slightly cropped and resized to 800 x 628.
This image was taken at an urban with light pollution. This is a
guided image. The location dictated somewhat short exposures due to the
light pollution. I have left the background somewhat light - not because
of light pollution, but becuase this whole ares is somewhat luminous as can be
seen in the wider field image above. This object is located in the constellation
of Cassiopeia. Horizontal FOV is about 28'
