Tucanae 47, a Globular cluster, reprocessed









LRGB image of Tucanae, NGC 104, globular cluster in constellation Tucana.16700 light years away from Earth and 120 light years across. Image field is about 30' x 30', half a degrees.

I did reprocessed this image, since at the time I didn't have good and functional calibration files.

RCOS ja Apogee U9000 camera. 

LRGB combo.
Luminance 12x300s and 8x150s, Dark and Flat calibrated.
Red 5x300s, Dark calibrated 
Green 5x300s, Dark calibrated 
Blue 5x300s, Dark calibrated 

Raw data is shared with Petri Kehusmaa and J-P Metsavainio

Processing workflow:
Image acquisition, MaxiDL v4.xxx
Stacked and calibrated in CCDStack.
Deconvolution with a CCDSharp, 10 iterations
Levels, curves and color combine in PS CS3.
