2008; Camera:
Artemis285
Exposure: 10 x 3 min Luminance exposure (bin 1x1) with Baader IR Block Filter; 8
x 2 min RGB (bin 2x2)
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. Channels were co-registered in Astroart. The 3
minute IR block exposures were used for the main luminance construction with
level adjustments and curves to bring out object features. LRGB combine was done
in Photoshop. G2V factors applied to color channels. Final Image size is approximately 1392x1040
This image was guided; North is up. The image was taken with fairly good conditions at a
dark site. M14 is one of 7 Messier Globular Clusters in Ophiuchus. The
others are M9, M10, M12, M19, M62,M107. M14 is the most distant of the 5 at about
30,000 light years form Earth. But it is likely the most Luminous at roughly
400,000 times more luminous then our Sun. This image replaces an earlier image that can be
seen in the Archives here. Horizontal FOV is
20'
Image Center is approximately - Equatorial 2000: RA: 17h 37m 36.0s Dec: -03°15'00"
