Tutti i colori del cielo

Il bravo astrofotografo indiano Soumyadeep Mukherjee ci ha mandato questo lavoro fotografico dal titolo: “10 Days of Nearness” in cui testimonia l’avvicinamento apparente tra Giove e Venere e la differenza dei colori del cielo che cambia giorno per giorno. I differenti colori del cielo dipendo dal fenomeno della diffusione atmosferica, ovvero dall’interazione tra la luce solare e le particelle in sospensione aerea.

Ecco le parole dell’autore che ci descrive la ripresa:”For the last couple of weeks, venus and jupiter had stolen the attention of astrophotographers! They were inching close to one another, slowly but surely. I was lucky enough to capture their relative movement for the last 10 days. Another interesting find for me was the ever changing hue of the sky after sunset! They do add a lot to the final image. I used the same set of equipment, Nikon D5600, Sigma 50mm and Benro Rhino Tripod throughout. The aperture was maintained at f/2.8 and ISO was kept 200 for all the images. Shutter speed varied from 1/3 seconds to 1 second, depending on the lighting condition. All the images were taken at a similar time, between 6:10 PM to 6:20 PM“.
