Description

I captured this data already last May but somehow never finished processing it. Glad I gave it a second chance...
The Ha data was simply added to the red channel in the linear state with a ratio of 70:30. Then SPCC was used (again) to get rid of the green cast created by that operation. This tip was shown just recently in one of the official PI videos and it worked great for me.
