Double Arches of Hehuan Mountain

• Connection to Category: Once a year, a rare window appears in March, the Winter Milky Way sets as the Summer Milky Way begins to rise. For a short moment, both arches share the same sky on spring night. It takes effort and patience to align and time blend everything on post processing for this unique nightscape perspective in Taiwan. I am so proud of I make it in the same night and bring this vision to the one who love dark sky.
