I’m sumitting an image of M33 galaxy. It is a reprocessing of a few days ago in which I added Ha to highlight the emission nebulae of the galaxy. Taken from Montejo de Tiermes, Soria, Spain.
It can be seen in all its splendor NGC604, the largest emission nebula in this galaxy.
It has 9h of total exposure.
