bi colour Bubble nebula

Jay Bird

Skywatcher ED80 – ATK16HR – EQ6 – finderguider 50mm.
Filters: astronomik ha – baader oiii

9x600s ha
9x900s oiii.

A narrowband attempt on NGC6735 bubble nebula.

I initially wanted natural colours, but the OIII signal was so weak that it came out orange.
After some photoshop gymnastics i managed to get something resembling hubble palette from the two filter channels.
