🌠 What Is the Perseid Meteor Shower?
-
Origin: Caused by Earth passing through debris left by Comet Swift-Tuttle, which orbits the Sun every 133 years.
-
Meteor Speed: Meteors hit Earth's atmosphere at ~36 miles per second (≈58 km/s), creating bright streaks or fireballs.
-
Name: The shower is named after the constellation Perseus, where the meteors appear to radiate from.
📅 Peak Viewing Time (2025)
-
Active Period: July 17 – August 24
-
Peak: Night of August 12–13, especially between midnight and 5:30am BST
-
Moon Conditions: The Moon will be 84% illuminated, which may wash out fainter meteors
-
Best Strategy:
-
Use trees or buildings to block moonlight
-
Head to dark-sky locations like the coast or countryside
-
Let your eyes adjust for 20–30 minutes
-
🌌 Radiant Point
-
Location: In the constellation Perseus, near the Double Cluster (NGC 869 and NGC 884)
-
Direction: Look northeast, below the “W” shape of Cassiopeia
-
Altitude: The radiant climbs highest just before dawn, improving meteor visibility
📸 DSLR Settings for Meteor Photography
-
Lens: Wide-angle (14–24mm), fast aperture (f/2.8 or wider)
-
Aperture: f/2.8 or wider (e.g., f/1.8) to maximize light intake
-
ISO: 1600–3200 (adjust based on noise tolerance and moonlight)
-
Shutter Speed: 10–20 seconds (long enough to catch meteors, short enough to avoid star trails)
-
Focus: Manual focus set to infinity (use live view and magnify stars to fine-tune)
-
White Balance: Daylight or 4000K–5000K for natural tones
-
File Format: RAW for maximum post-processing flexibility
-
Intervalometer: Recommended for continuous shooting over several hours
Bonus Tips:
-
Use a sturdy tripod and remote shutter release or timer to avoid camera shake.
-
Point your camera slightly away from the radiant to catch longer meteor trails.
-
Consider stacking multiple exposures to create composite images of multiple meteors.
