IC 1848 in Cassiopeia
|
Scope: Megrez II f/2.6 Location: Laguna Mountains CA; 17 Sept. 2004 Camera: ToUcam SC3 Exposure: 12 x 36 sec and 16 x 10 sec Luminance exposures with Baader IR Block Filter, 6 x 270 sec H-Alpha exposure; 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 Nebulosity was extracted
from HA and then combined with the 36 sec IR for Luminance in Photoshop -
The 10 sec IR was used to minimize some star bloating. In addition, since some
of the brighter stars were still somewhat large, a Photoshop minimum filter was
selectively applied. 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.
