A warning light blinked amber. Recommendation: With this resolution, star trailing will occur at exposures longer than 12 seconds using the NPF rule. : The focal length of the telescope or lens in millimeters

He spent the next hour playing with the "Arc" feature. The "Astro FOV Calculator 2021" wasn't just a math tool; it was a pre-visualization engine. He dragged a digital overlay of the Milky Way onto a Google Maps satellite view of the desert formation he planned to visit. He saw that at 14mm, the rocks would be too far away. He needed to be closer, or he needed to shoot a panorama.
