today's post begins with a couple of reviews: the first concerns an astronomy book for beginners, written by Daniele Gasparri and downloadable network, and of course you can also buy in hard copy. The second review is directed to the fans instead of shooting digital astronomical, and in this sense the book written by his friend Lorenzo Comolli and Daniel Cipollina is presented as a comprehensive guide to the difficult art digital image processing. All information on buying in volume this page of the site of Lorenzo.
The same Lorenzo Comolli has also recently created this beautiful time-lapse site observation huts Cosola Apennines (Alessandria).
Another wonderful movie this time obtained by the probe Solar Dynamics Observatory (SDO), shows the development of a large group of spots ( SpaceWeather , 4 MB to download). The Hubble Space Telescope has taken a sensational image of the galaxy NGC 2841, a spectacle of fine spirals ( Universe Today). The Messenger probe proposes an unusual photo-mosaic of the solar system, seen from an internal position, next to Mercury ( Universe Today).
If you have never seen a hummingbird-robot, start with this, it is not science fiction ( Paul Attivissimo ).
Finally, some recent photos taken by me and Clare: The last four of this album filming a striking solar halo, with a rare and sundogs upper tangent arc, observed on February 12 from nozzle Margosio, a pass along the Zegna Panoramic Road (Biella). In this other album, however, the images taken on Feb. 19 in the mountains above Condove (Torino), including the opening photo of snowdrops.
