Scope: C8 f/7.3; Location: Dos Picos Park, Ramona, CA;
8 June 2005; Camera:
Artemis285
Exposure: 7 x 120 sec Luminance exposure (bin 1x1) with Baader IR Block Filter;
6 x 60 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. . Final LRGB combine was done in Photoshop using Luminance Layering (or
LLRGB). Color
balancing and final touches were done in Photoshop - the overall image seemed
biased toward blue so the blue channel was attenuated to balance RGB histograms.
Image touch up included background noise subtraction on the Luminance master. SGBNR
(PixInsight LE)
was used to smooth remaining background noise on the final result.
Final Image size is approximately 1392x1040
This image was guided; North is up. Globular Cluster NGC 5466 is a rather dim
globular at a 9.1 magnitude. As can be seen from the image, this is a somewhat
loose globular all the way to its core. NGC 5466 is located in the constellation
of Bootes near the Canes Venatici border - it's distance is estimated at 51,800
light years. In the very upper right of this image are two dim galaxies - PGC
50187 is the brighter larger object and just above that is PGC 1849788. Horizontal FOV is
21'
Image Center is approximately - Equatorial 2000: RA: 14h 05m 27s Dec: +28°32'06"
