Tarantula and Surrounds in Narrow Band

With a near full Moon collected this data over the last two nights as they were the first clear nights for quite some time.

Camera Canon 5DH, 150mm achro at f/4.25, Astronomik 13nm HA and O3 filters. Fridge at -10C.

Exposures 20x( 2m, 4m and 8m ) at 1600 ISO for both HA and O3.
Mapped HA to red, O3 green to green, O3 blue to blue.

Gradients were a problem as the full Moon does get through 13nm NB filters.
