M51 (Galaxy)

After several bad weather days, and what it is much worse, loads and loads of work (congresses, end of the academic year...) the Friday evening look promising to go out and enjoy the sky. Both Antonio and myself wanted to go for a visual observation session in Sierra Nevada for a long time. La Azotea is a great place to learn astrophotography, but for visual observations it has lots of drawbacks.

The evening was quite complicated because I had to go to Cullar Vega to finish the preparations for the photography exposition Cosmos: Vistas desde la Nave Tierra of the S.A.G.. It took more time that we initially planned and we finished it  at 8PM. After that I went to Armilla where we loaded Antonio's Pequeñín in the van. Around 10PM we went to Granada to pick up more gadgets, supplies and, of course, some additional winter clothes. Finally, we began our trip to Sierra Nevada around 11PM.

The night of Saturday March 14th, was again very good for astronomy. After the set up of all the devices, and done a precise alignment to the Polar star, the main goal for this night was the Orion nebula through the refrigerated QHY6 CCD, besides other type of objects as galaxies. The humidity oscillated in the whole night around 50 - 60% and the temperature was about 10 grades which was very bearable.
