How to Photograph a Lunar Eclipse

Quick Scoop

If you plan a bit, use a tripod, and adjust your exposure as the Moon darkens, you can capture a sharp, dramatic lunar eclipse even with modest gear. The key is: stability, manual control, and changing your settings throughout the different phases.

Gear Checklist (What You Really Need)

  • Camera with manual controls (any DSLR or mirrorless, even advanced compact).
  • Sturdy tripod to keep the Moon sharp during long exposures.
  • Telephoto lens (ideally 200–600mm) if you want a big Moon; a wide lens if you want landscape + Moon sequences.
  • Remote shutter or self-timer to avoid camera shake.
  • Extra batteries and memory cards (eclipses last a while).
  • Optional: star tracker or equatorial mount for very long exposures during totality.

Think of the eclipse as a slow celestial performance: your job is to be the calm camera operator who never leaves their tripod.

Planning Before the Eclipse

1. Know when and where

  • Check local eclipse time (start, maximum, end) on astronomy or eclipse-planning apps and websites so you know how long you’ll be shooting.
  • Scout a location with an unobstructed view of the sky and a clear eastern or western horizon, depending on where the Moon will rise or set.
  • Decide your style:
    • Close-up, detailed Moon.
    • Wide shot with landscape and a tiny Moon.
    • Multiple-Moon composite or timelapse sequence.

2. Compose a story, not just a Moon

  • Look for foreground subjects: buildings, trees, mountains, monuments, or a skyline to make the image feel grounded and dramatic.
  • If you plan to leave the camera static for a multi-moon composition, compose so the Moon moves through an interesting part of the frame over time.

Core Camera Settings by Phase

The big challenge: the Moon goes from bright (partial phase) to very dim (totality), so your settings must evolve.

1. Before and during partial eclipse

  • Mode: Manual (M).
  • ISO: Start low, around ISO 100–200 for maximum quality.
  • Aperture: Use a lens’s sharp sweet spot , typically around f/4–f/8 for telephotos.
  • Shutter speed: Use relatively short exposures to avoid motion blur because the Moon moves fast across the frame.
  • Focus:
    • Focus carefully on the Moon before the eclipse starts, using live view and magnification if possible.
* Then switch off autofocus so the camera doesn’t hunt in the dark.

Example starting point (telephoto, partial phase):

  • ISO 100–200, f/5.6–f/8, 1/125–1/250 s (then fine-tune based on your histogram).

2. Approaching totality

As the Earth’s shadow covers more of the Moon, it gets darker and redder.

  • Gradually increase ISO: move up to ISO 400, 800, then higher as needed.
  • Open aperture: move toward your lens’s widest aperture to let in more light.
  • Slow shutter: lengthen the exposure, but watch for motion blur; many photographers stay below a few seconds if not tracking.

3. Totality (the “blood moon” look)

During totality the Moon can be very dim.

  • ISO: You may need ISO 800–3200 or more depending on your lens and how dark the eclipse is.
  • Aperture: Use the widest aperture your lens allows.
  • Shutter: Exposures can run up to several seconds, but try to keep them as short as you can while maintaining brightness to reduce blur.
  • Take several exposures at different settings (bracketing) so you don’t miss the best combination.

Framing and Composition Tips

Close-up Moon shots

  • Keep the Moon near the center of the frame where most lenses are sharpest and focus is most accurate.
  • Watch for overexposure: if the Moon looks like a white disk with no detail, shorten your exposure or lower ISO.

Wide-angle eclipse with landscape

  • Use a wide lens and a tripod; aim for an interesting foreground subject plus the path of the Moon.
  • As the Moon moves from one side of the frame to the other, you can shoot a series of images and later stack them as multiple Moons across the sky.

Multiple Moons / composite idea

  • Take images at regular intervals (for example, every 5–10 minutes) throughout the eclipse so the Moon is evenly spaced in a final composite.
  • Keep the camera locked on the tripod in the same orientation so aligning images later is easy.

Technique Essentials (To Avoid Blurry or Shaky Photos)

  • Tripod always: Even for short exposures, a tripod keeps everything stable and lets you keep framing consistent across many shots.
  • Remote or self-timer: Trigger the shutter without touching the camera to avoid vibrations.
  • Turn off image stabilization when on a solid tripod (if your lens/camera manual recommends that) to avoid micro-movements.
  • Check focus often: temperature changes and accidental bumps can shift critical focus; zoom in on playback to confirm the Moon is crisp.
  • Shoot in RAW: You’ll have more flexibility to recover details in shadows and highlights and fine-tune the red tones of the eclipsed Moon.

Timelapse and Sequence Ideas

If you want something more cinematic:

Basic timelapse approach

  • Decide your final video length (for example, 30–60 seconds).
  • Choose an interval (for example, one frame every 20–60 seconds, depending on how smooth you want the motion and how long the eclipse lasts).
  • Make sure your memory card and batteries can handle hundreds of frames over several hours.
  • Keep exposure adjustments gentle and gradual; big jumps in brightness can look jittery in motion.

Bracketed timelapse (advanced)

  • You can technically shoot bracketed exposures for each frame to capture more dynamic range, but aligning and processing many HDR frames for an eclipse sequence can become complex and time-consuming.
  • Many photographers end up using single well-exposed frames instead of HDR for smoother processing.

Common Mistakes to Avoid

  • Letting the camera stay in auto mode: it will struggle as brightness changes and can produce inconsistent exposures.
  • Forgetting to adjust settings as the Moon darkens or brightens: plan rough exposure steps for each phase in advance.
  • Overlong shutter speeds on a fixed tripod, leading to a smeared Moon instead of a crisp disk.
  • Not checking test shots at high magnification to confirm sharp focus and avoid disappointment later.

Simple Example Workflow (Start-to-Finish)

  1. Arrive 45–60 minutes early, set up tripod and frame your composition.
  2. Focus on the bright Moon before the eclipse using live view, then switch to manual focus and leave it.
  1. Start shooting during the partial phase with a low ISO, mid aperture, and short shutter speed.
  2. As the eclipse deepens, increase ISO, open the aperture, and lengthen shutter speed in stages.
  1. During totality, use your widest aperture, higher ISO, and a longer exposure, taking several variations.
  1. Keep shooting at regular intervals if you want a multi-Moon composite or timelapse.
