๐ Introduction
Professional DSLR and mirrorless camera systems provide the light collection needed to capture high-density ion structures.
โฑ๏ธ Quick Answer
Set your mode to manual (M), lens focus to true infinity, ISO to 3200, aperture to f/2.8, and use a 2-second shutter delay.
๐ฎ Why It Happens
Fast shutter speeds (1-4 seconds) resolve sharp, individual auroral rays during active storms. Slower shutters (8-15 seconds) smooth out quiet, diffuse arcs.
๐จ Visual Explanation
Using a shutter delay is like stepping back from a rifle to avoid trigger-squeeze vibration.
โ Common Beginner Mistakes
Relying on autofocus, which will hunt endlessly in near-total darkness.
๐ Frequently Asked Questions
What file format should I shoot in?
