July 2014: M106

After some time without imaging (I’m very busy with my astrophysics master program), I came back to my CCD with this galaxy. The imaging session was abruptly terminated when some high clouds had my star guide lost. I could only cath 3 subs for each filter. Althpugh I used 500-second exposures for my subs, this was not enough to clearly uncover the weak and subtle external parts of this beautiful spiral. I trued to do my best while processing, to extract light from this area. As always, deconvolution worked miracles on the central part of the galaxy.

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:
