Have you ever dreamed of capturing stunning images of the night sky but were discouraged by the complexity and cost of astrophotography? Meet Reddit user intercipere, who has devised an ingenious solution: a 3D-printable, star-following mount for DSLR cameras that makes astrophotography accessible and affordable for hobbyists.
Overcoming the Earth’s Rotation
One of the biggest challenges in astrophotography is the Earth’s rotation. As the Earth spins, the stars appear to move across the sky, causing star trails in long-exposure photographs. To counteract this, astrophotographers use specialized mounts that track the stars, keeping them centered in the frame. These mounts can be expensive and complex to operate, but intercipere’s 3D-printed mount offers a simple and affordable alternative.
How It Works
The mount consists of a 3D-printed base, two stepper motors, an iRobota Uno microcontroller, and a 16×2 LCD shield for user input. The user inputs the RA/DEC coordinates of the desired target, and the mount automatically moves to that location in the sky. The stepper motors then rotate the camera to compensate for the Earth’s rotation, allowing for long exposures of distant objects.
Impressive Results
Despite its simplicity and affordability, the mount delivers impressive results. In light-polluted areas, where astrophotography is typically challenging, the mount can track for at least four minutes, enabling the capture of clear astrophotographs. Intercipere has shared an example photo of the Andromeda galaxy taken with the mount and a cheap lens in a heavily light-polluted area, demonstrating its capabilities.
DIY Enthusiasts Rejoice
The mount’s open-source design makes it accessible to DIY enthusiasts and hobbyists. The 3D-printable files and detailed instructions are available on GitHub, allowing users to build their own mount at a fraction of the cost of commercial alternatives. This democratizes astrophotography, making it accessible to a wider range of enthusiasts.
Conclusion
Intercipere’s 3D-printable, star-following mount is a game-changer for astrophotography enthusiasts. It offers a simple, affordable, and effective solution to the challenges posed by the Earth’s rotation, making it possible to capture stunning images of the night sky even in light-polluted areas. With its open-source design, the mount empowers DIY enthusiasts to build their own astrophotography setup, fostering a sense of community and innovation.
Bonus: Astrophotography can be a transformative experience, connecting us with the vastness and beauty of the universe. As Carl Sagan once said, “Look again at that dot. That’s here. That’s home. That’s us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives.” Embarking on an astrophotography journey is a humbling reminder of our place in the cosmos and can inspire a sense of awe and wonder.
