Adjust the mood of your photo, add constellation art and a frame, and make something personal. Keep the people and the landscape that made the moment yours.
What’s next
Our first priority is making the current AstroTrip app better to use. We plan, design and develop everything ourselves, and test it under the night sky.
We will keep improving the app based on what users tell us. Several new features are already being planned, so stay tuned.
We will share each one as it takes shape.

Our journal follows real observing experiences, equipment we have used and the process of making products. Articles are currently in Japanese.
