NGC 5033 in Canes Venatici



Scope: C8  f/6.2, Location: Blair Valley, Anza Borrego Desert, CA, 26 April and Dos Picos Park, Ramona, 31  May, 2008;  Camera: Artemis285

Exposure: 18 x 9  minutes (1x1 bin - Blair) and 12 x 6 minutes (2x2 bin - Dos Picos) Luminance exposures with IR block, 5 x 3 minutes RGB exposures (2x2 bin - Blair).

Processing: Images were captured Artemis Capture (as FITs). Aligned/stacked and dark subtracted in Astroart with Sigma Combine. Luminance and Color channels were scaled and rough color balanced in Astroart.  Gradient removal was performed on the Dos Picos exposure stack. Channels were co-registered in Astroart. The 6 minute IR block (2x2 bin) exposures were used for the main luminance construction. The (1x1 bin) exposures were used for improved star size and galaxy detail. Level adjustments and curves adjustments were used to bring out object features. LRGB combine was done in Photoshop. G2V  factors applied to color channels. Selective sharpening (with mask) was used to enhance galaxy features. A light noise reduction was applied with PixInsight LE SGBNR.  Final touches were done in Photoshop.  Final Image size is approximately 1392x1040
