Description

RGB calibration in Theli using UCAC4, not NOMAD as with the other pics, yielding less blue stars.

Original: added BW red channel as blended luminance layer to bring out details and the faint stuff.

Version B: standard RGB processing.

Comments on which approach works better highly welcome!
