Description

This version has less noise reduction than the previous version. Don't really know which one to keep. Both have merits.

The previous version had added noise reduction after combining the Ha and OIII.

This version none, just stretching.

Combined:

R:Ha

G:Ha*.85 + OIII*.35

B:Ha*.35 + OIII*.85
