C8 f/2.6 Location: Laguna Mountains (IR, HA Exposures) CA, 14 Aug. 2004 and Del
Mar (RGB Exposures) 16 Aug. 2004 Camera: ToUcam SC3
Exposure: 5 x 240 sec H-Alpha exposures, 8 x 80 sec exposures with IR Block
filter, 12 x 12 sec each RGB exposures. One set of exposures for each
frame of a four frame mosaic.
Processing: All exposures captured in K3CCDTools. Alignment and stacking was done with Registax and saved as
FITs. HA, and LRGB channels were co-registered in Astroart and Red combined for red. These combinations and LRGB combine were done in Photoshop. Luminance Layering was used. Each quadrant of the mosaic was color balanced in Photoshop and background smoothed with
SGBNR in PixInsightLE. Final mosaic joining and touch up in Photoshop.
The Luminance portion of the image was taken at a dark site and the Color
exposures were made two days later in my light polluted neighborhood in Del Mar.
I couldn't get the color exposures the same night as the Luminance exposures
because, well, I just got too tired. This object is catalogued as Cederblad
214 but it is often associated with NGC7822 which lies just North of this Field
of View. Horizontal FOV is about 45'
