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.

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.
