An interesting idea Patrice. What time in the morning would that be, maybe I'm still awake? Do you think the Pentax M 100 or 200mm (on film) would be a good lens for that, what did you use in your GESO? greetings Markus

At this very day, it will cruise near the very bright planet Jupiter and the bright start Antares, in the Scorpion constellation. The trio will raise at the east (as usual), shortly before the sun, wherever you live. There are two challenges here: - doing a nice composition, of general photographic interest, and not only a pure astronomical "documentary" photograph, that would please only astronomers. - getting up at this time of the morning (and of the year in northern countries) I will do my best to produce something, and I invite enthusiasts to join me. To get an idea of what to expect, I did a simulation with the great software Stellarium, visible here: http://www.lacouture.nom.fr/gallery/v/divers/2007-02-12-MJA/2007-02-12-Moon- Jupiter-Antares-crop.jpg.html http://tinyurl.com/ytmx8k This simulation is for Marseilles, France, but the configuration should be similar wherever you live in the northern hemisphere. The moon inclination will vary according to your latitude, and will be reversed in the southern hemisphere, but you get the idea. FYI, my shot of last saturday with the longest focal was approx 125mm. This is not really a "synchronicity" project, as everyone must take the picture before dawn wherever (s)he lives, before the moon and the rest disappear into the sun's light. If the number of participants is enough, I'll probably set up a gallery somewhere to host the images. If this bothers you, sorry for that, otherwise, enjoy!
