April 2014… with the 1,5m telescope at OSN!

Yes! My colleagues (Sara, Javi, Gunther, Erik) and I had the chance to remotely use, for three nights in a row, the telescopes of the Observatorio de Sierra Nevada. This observatory, which is almost 3.000m high up in the mountains, has two big, professional telescopes (90 and 150 cms). It is  not usual for this kind of observatories to allow use to non-professionals, but this was a remarkable exception thanks to the Valencian International University in which we are currently developing a astronomy and astrophysics master program. We were brightly assisted by the staff at OSN.

We used our nights for some science projects, and had time to image some wonders of the sky. Working at bin2x2, we were at a theoretical 0,46 arcsec/pixel  scale, limited in fact by the seeing. With a FOV of only 8 arcmin, the 1024X1024 pixels of the VersArray CCD delivered an extraordinary amount of information, so we aimed at tiny but interesting objects.

M97, the Owl Nebula (narrowband), and M82 with its supernova SN2014J were two of these objects:
