Photographing Perseid meteor shower won't be ruined by moonlight. Here's how to capture the best pictures from this year's event
Photographing the Perseid Meteor Shower During a Full Moon
Preparing to capture the Perseid meteor shower during a full Moon requires careful planning and the right equipment. Here's a guide to help you make the most of this celestial event.
Equipment and Setup
A DSLR or mirrorless camera with manual controls is recommended for this task. Attach the camera to a sturdy tripod and use a wide-angle fast lens (f/2.8 or lower, 14-24mm focal length) to capture a large part of the sky.
To ensure stability and adjust the pointing angle, a tripod is essential. A wide-angle fast lens allows for a larger field of view, which is beneficial during the Perseid meteor shower.
Exposure Settings
Set your exposure time short enough to avoid overexposure from the moonlight and star trailing. Following the 500 Rule can help determine the optimal exposure time. Typically, exposures between 20–30 seconds should suffice. Use a moderate ISO (e.g., 800) to balance brightness and noise.
Automation
To take continuous shots over an extended period, use a lockable remote shutter release or intervalometer. This automation increases the chance of capturing meteors without physically touching the camera.
Patience and Adaptation
Because moonlight conditions are challenging, adjust aperture, ISO, and exposure times as needed during the session to optimize results. Remember that the goal is to capture a shot of the trail, with perhaps a few bright stars recorded to allow measurements to be taken.
Moonlight Impact
Bright moonlight causes overexposure near the Moon and limits how long you can expose other parts of the sky without washing out details. To minimize this effect, avoid pointing the camera directly at the Moon.
Adjusting the Camera's Position
The sky appears to move relative to a fixed pointing angle, so adjusting where the camera points over the course of the evening is advisable. This technique increases the chances of capturing meteors as they streak across the sky.
Test Shots and Adjustments
Take a test shot to check the exposure and adjust as needed. Avoid going below 10 seconds; if you reach that, begin lowering the ISO.
Challenges and Solutions
Moonlight causes two main issues in meteor photography: over-exposure of the area of sky near the Moon and limiting exposure times of other areas of the sky. To mitigate these issues, stop the exposure immediately after a meteor trail to minimize the effect of moonlight on the rest of the image.
In reality, taking exposures when trails occur would be the best option, as it would eliminate star trails and reduce the number of wasted exposures. However, this approach requires precise timing and may not be feasible for all photographers.
Following these approaches will help balance the bright moonlight's impact and maximize your ability to capture Perseid meteors during a full Moon. The Perseid meteor shower will be challenging for naked-eye observers due to a large bright Moon near the position of the radiant. However, with the right equipment and techniques, you can capture stunning images of this celestial spectacle.
Key Dates
The peak of the Perseid meteor shower is on 12 August.
