Scope: C8 f/8;
Location: Dos Picos Park, Ramona, CA; 15 March, 2007; Camera:
Artemis285
Exposure: 8 x 330 sec Luminance exposures with IR Block Filter (bin 1x1);
6 x 120 sec RGB (bin 2x2)
Processing: Images were captured in Artemis Capture (as FITs). Aligned/stacked
in Registax 4 and saved as FITS. Luminance and Color channels were numerically
scaled and color balanced in Astroart. Channels were co-registered
in Astroart. Luminance exposure had central gradient removed in Astroart. Curves and Levels applied in Photoshop to optimize object
features. Final LRGB combine was done in Photoshop using Luminance
Layering (or LLRGB). G2V color calibration
factors were applied to
the color channels for color correction. Selective sharpening with layer
mask was applied to galaxy features. Color balancing and final
touches were done in Photoshop. A light background noise reduction
was performed on the Luminance channel using SGBNR in PixInsight prior to LRGB
combine. Final Image size is approximately
1392x1040.
North is up in this image. M106 is an bright spiral galaxy located in the
constellation of Canes Venatici. M106 has active star formation that can be seen
in the red regions of the spiral arms. The
distance of M106 to Earth is approximately 25 million light years. This
image replaces and earlier image that can be seen in the Archives
here. Horizontal FOV is about 20'
