Horsehead nebula - Ha and Oiii Hubble palette.

[Andywilliams]

Lesson for the day …. Never throw any data away, ever.
Thank goodness for external hard drives.
As my Pixinsight processing techniques improve, I can rescue what I previously thought was dud data.
This is Barnard 33, the Horsehead nebula in Orion.
Data was captured back in March of this year and reprocessed today.
