Each month the Observatori Astronòmic del Montsec (OAdM) of IEEC publishes an outstanding image from the observations made there. In September the protagonist is The galaxy NGC7331.
This image made with the Joan Oró telescope, from the Astronomical Observatory of the Montsec, reveals dozens of galaxies much farther than the stars that are seen in the foreground. The most imposing one, a spiral known as NGC7331, is about 50 million light years away and is visible throughout the fall in the constellation of the Pegaso. This is a galaxy that is very similar to our Milky Way Galaxy. In addition, some groups of galaxies can be seen in the background, more than 10 times farther than the protagonist of the image.
To do this, the telescope Joan Oró needed almost 2 hours of total exposure time, combining several broadband filters.
