This is an image that I always had curiosity to do, M-42 in narrow band. I know about the existence of some dark nebula embedded to M-43. In this image I think I was able to capture this dark right in the "junction" of M-42 and M-43. The presence of this dark nebula makes M-42 an even more amazing object for research.

The image took 17 days to be completed because of the weather conditions. The capture scheme was:
Ha: 12x900sec bin 1x1
O3: 15x900sec bin 1x1
S2: 20x900sec bin 1x1

Bias, darks and flats applied.
