“I am a Japanese amateur astrophotographer.

Since 2009, I have been working on astrophotography of nebulae and galaxies.
I’ve shot hundreds of objects so far and never lost interest.
Japan has large populations despite its small land area, where light pollution is everywhere and the westerly wind passes over the sky, so the airflow is not stable.
Even so, we are working with many friends to capture the beauty of the universe.
As of 2020, I am constructing a remote observatory with my friends at the foot of Mt. Fuji.

In the future, I plan to improve the quality by increasing the quantity of photograph opportunities and the exposure time.”
