This Backyard Astronomer 3D-Printed a 60-Segment Observatory—Then Shot a Wild 360° Meteor Shower

Under the quiet canopy of a late summer night, one independent maker set out to solve two of amateur astronomy’s toughest challenges at once: building an affordable physical dome and capturing the entire night sky without digital shortcuts.

Armed with an array of 3D printers and a passion for deep sky imaging, the builder created BASTION—a custom 60-segment printed observatory shell designed to house specialized astronomical gear. But during the peak of the 2026 Perseid meteor shower, the incomplete dome took on a brand new role as the central foreground subject in a massive 360-degree starlapse experiment.

Using a specialized dual-lens 360 camera, the builder captured roughly 400 uncompressed RAW images from dusk until dawn. Each frame clocked in at a staggering 120 megabytes, shot at 25-second exposures under ISO 1600. The result was a breathtaking, continuous record of meteors slicing through the summer constellations above the futuristic shell.

Yet, bringing the dynamic sky to life presented a digital nightmare. Standard panorama and astrophotography software frequently struggle to stitch high-contrast night sky images seamlessly. The artificial intelligence algorithms built into modern editing applications often distort faint star fields or create harsh, ugly seam lines where the camera’s two lenses meet.

Rather than letting automated AI tools stitch the sequence—and risk erasing delicate meteor streaks in the process—the creator chose an uncompromising path. They began hand-building a custom Photoshop action script to manually edit and stitch all 400 massive RAW files without a single drop of AI intervention.

The initial sequence preview quickly caught fire across online astronomy communities, sparking a fierce clash over the state of modern astrophotography.

One observer praised the project’s raw digital craftsmanship, noting that maintaining manual control over individual pixels is the only way to preserve authentic astronomical data. Another supporter marveled at the BASTION structure itself, arguing that modular 3D-printed domes represent the future of accessible, open-source stargazing.

Skeptics, however, were quick to challenge the setup's optical choices. One critic pointed out that wide 360-degree fisheye lenses inherently compress and distort distant light, arguing that traditional prime telephoto lenses yield far sharper scientific images of meteor showers. Another commenter questioned the massive time commitment, claiming that refusing to use automated stitching algorithms is an impractical stand against helpful technology.

Despite the pushback, the builder remains committed to refining both the custom editing workflow and the physical observatory, proving that backyard astronomy is alive, well, and bolder than ever.
