Description

This is my second attempt to do narrowband imaging and processing in SHO. The RAW data were hard to handle - even with a focal lenght of 800mm there is no region without nebula... :-)

This time I tried to produce three varying looks by using different color weights:

a) classic hubble composition with a shade of orange color
b) the "real" hubble composition
c) RGB-style
