L’OPOD di oggi ci porta una ventata di freschezza e va alla fotografa svizzera Angel Fux per aver ripreso l’arco del Gegenschein tra gli archi della Via Lattea:
Ecco le parole dell’autrice:
“It took months of planning, three nights of acclimatization at 3,100m, a window that nearly disappeared twice because of wind, a bank holiday that grounded helicopters, a pilot found last minute on the Italian side of the border, temperatures around minus 25°C, a night that got windier than forecasted, and forty hours of editing with a process I had never used before. What I set out to capture was the double Milky Way arch, the only night of the year where both arms of the Milky Way are visible above the horizon. The winter arch first, then the summer arch carrying the galactic core, from a summit with a view of the Matterhorn that almost no one ever sees.
What I didn’t plan for was the Gegenschein, a rare counterglow caused by interplanetary dust reflecting sunlight, appearing as a third faint arch crossing the frame. A triple arch, in the end. The final image is a tracked panorama built from over 260 individual exposures: 17 panels for the winter arch and 16 for the summer arch, each panel a stack of 4 frames at 40 seconds, supplemented with H-alpha data, plus 32 landscape shots at nautical twilight. The working folder came to around 300GB. I am deeply grateful to @lehnerrichi and @arnaudlehner , who made this safe and possible, and to @begibakar_travel , who taught me the processing workflow that brought this image to life. And big thank you to my loved ones for their endless support. Dent d’Hérens, Swiss Alps, 4,200m”.
Cari lettori, è giunto per me, Marco Meniero, il momento di salutare questa rubrica. Grazie per avermi accompagnato lungo questo percorso: vi auguro di continuare a trovare tra queste pagine curiosità, ispirazione e nuove idee. Con questa foto interrompiamo gli OPOD per la pausa estiva. L’OPOD tornerà il 7 settembre con stupende foto inedite. Vi lascio nelle mano sapienti dei miei collaboratori storici Marcella Botti e Alessandro Fabi.
