Artemis285
Exposure: 13 x 60 sec Luminance exposure (bin 1x1)with Baader IR Block Filter;
10 x 40 sec RGB (bin 2x2)
Processing: Images were captured Artemis Capture (as FITs). Aligned/stacked in Registax
3 and saved as FITS. Luminance and Color channels were scaled and rough color balanced in
Astroart. Channels were co-registered in Astroart. The 60 sec exposures were used as
the main luminance with level adjustments and curves to bring out dim stars. Final LRGB combine was done in Photoshop. Color
balancing and final touches were done in Photoshop. SGBNR was used to smooth background noise on the
final result.
Final Image size is approximately 1392x1040

clusters (from Earth) at about 8,000 to 9,000 light years distant. It contains a
noticeable Red Giant roughly central t the cluster an it is one of the 40 - 60
member stars in this cluster (all other stars in this field being either foreground
or background stars. The binary pair (Struve 131 - largest star - upper right in
the cluster) is not a cluster member. This image replaces an earlier image that can be
