Description

This is my first attempt at processing a narrow-band image.
We can make out shapes in the nebula's core, but with this narrow focal length, we shouldn't have expected much more.

C'est ma première tentative de traitement d'une image en bande étroite.
On croit deviner des formes dans le noyau de la nébuleuse, mais avec cette faible focale, il ne fallait pas en espérer beaucoup plus.
