Frequently Asked Questions
What focal length is best for astrophotography?
14-24mm is the classic Milky Way range. Wider lenses (14-20mm) capture more sky in one frame; 24mm gives more selective compositions with foreground anchoring.
Why fast apertures for astro?
Wide apertures (f/1.4-f/2.8) let you keep shutter speeds short enough to avoid star trails (typically <20 seconds at wide angles) while still gathering enough light for clean exposures.
Do I need a special astro lens?
No — any sharp, fast, wide-angle lens works. Look for minimal coma and low chromatic aberration in corners. The lenses listed here are popular for night work for those reasons.
