Thanks to a visitor observation time assigned to the team of Miguel Sanchez-Portal, we were fortunate to enjoy an observing night with the GRANTECAN 10.4 meter telescope in Roque de Los Muchachos Observatory (La Palma Island). The images and video shows the magic of this place for astronomy.
The following image is a false colour quick look of one of the observed objects: Abell370. A cluster of galaxies at 4775 Mly.
