M106 (ou NGC 4258) est une galaxie spirale située dans la constellation des Chiens de chasse située à une distance de 21 à 25 millions d'années-lumière du système solaire.
Le traitement a été compliqué car c'est une galaxie qui possèdent des régions d'intense activité de formation stellaire carctérisée par des nuages de gaz ionisé, (Ha) de couleur rouge que je voulais faire ressortir. il s'agit donc de ces petits jets de matière que l'on peut voir sur le négatif.

M106 (or NGC 4258) is a spiral galaxy located in the constellation of canes venatici at a distance of 21 to 25 million light years from the solar system.
The treatment was complicated because it is a galaxy which have regions of intense stellar formation activity characterized by clouds of ionized gas, (Ha) of red color that I wanted to bring out. it is therefore about these small jets of matter that we can see on the negative.
