This guide adapts the technical settings from PhotoPills' eclipse cheat sheet to the a6000's body and kit lens. It was written for the total eclipse of August 12, 2026 — the first to cross the Spanish mainland since 1905; from where I was it was only partial, and my photos didn't come out well (recap below). The phase-by-phase settings are still valid: the next total eclipse visible from Spain is August 2, 2027, this time in the south. Whatever your plans, don't debut your settings on eclipse day — rehearse with the Moon (Part 4) well in advance.
RECAP
What happened on August 12, 2026
That date is behind us. Here's what I saw, what went wrong, and what I'll do differently on August 2, 2027.
Eclipse day, from where I was PARTIAL · OUTSIDE THE PATH
The path of totality crossed northern Spain, a corner of northeastern Portugal, and the Balearic Islands; from where I was the eclipse was only partial. I shot the partial phases with a homemade filter and the photos didn't come out well: that day turned into a to-do list for the next one.
What I'll do differently on August 2, 2027 THE NEXT DATE
- No improvised filters. Certified Baader AstroSolar film or a compliant ND filter, mounted at the front of the lens and tested well ahead of time (Part 0).
- Nothing debuts on eclipse day. The Moon dry run (Part 4) is what separates a useful burst from losing the seconds of totality while fighting your camera.
- Be inside the path. In 2027 totality crosses southern Spain (Cádiz, Málaga, the coast of Almería and Granada). I'll pick my exact spot in advance and check the precise time and duration there (Part 1).
Goal for 2027: come home with the full sequence of phases, not another to-do list.
PART 0
The one thing you can't get wrong
Before we talk settings: the Sun doesn't forgive mistakes. Read this even if you skip the rest of the guide.
Golden rule EYE AND SENSOR SAFETY
Never look at the Sun directly — not with the naked eye, not through the camera's viewfinder, not through a lens — without ISO 12312-2 certified eclipse glasses or a solar filter fitted to the lens. A single unprotected second can burn the retina permanently, and painlessly: you won't notice until later.
- The lens filter stays on at all times except for the exact minute of totality (Part 3) — and only if you're inside the path of totality.
- Without a filter, sunlight focused by the lens can also fry the camera's sensor in seconds.
- Regular sunglasses, however expensive, offer no protection at all. Only ISO 12312-2 certified eclipse glasses are safe — cheap and widely available from opticians or astronomy shops.
One advantage the a6000 has over old DSLRs: its viewfinder (EVF) is an electronic screen, not a direct optical tunnel to the Sun. Looking through the viewfinder adds no extra eye risk — as long as the filter is on the lens. The real danger is always the light entering the front of the glass, not how you view it.
A solar filter (Baader AstroSolar film, an ND 100,000 filter, or certified "welder's glass #14") goes on the front of the lens, covering the entire optic — never behind it, near the sensor. Get one — or make one from certified film — with plenty of time to spare, and test it before the event: an untested homemade filter is the surest way to come home with no photos (see the recap above).
PART 1
The day, the spot, and the bag
The 2026 eclipse reached Spain right at the end of the day, with the Sun very low, and it dictated where to stand. For 2027 the totality will cross southern Spain: check the exact time and the Sun's height for your precise location — they change by city — because that decides which horizon you need.
Where and when NEXT DATE · AUGUST 2, 2027 · SOUTH
On August 12, 2026 totality swept across northern Spain at the very end of the afternoon, with the Sun close to the horizon. The next date is August 2, 2027: the path will enter through the Strait of Gibraltar and cross southern Spain (Cádiz, Málaga, the coast of Almería and Granada). You'll need a clear horizon in the direction of the Sun at that hour: no mountains, buildings, or trees in the way. Check the exact time, the duration of totality, and the Sun's height for your specific location before you go — they vary a lot by city — using Spain's national observatory simulator or PhotoPills.
Mission: before the day itself, visit your chosen spot at the exact predicted time and check with your phone that nothing blocks the Sun from there.
The eclipse bag CHECKLIST
| Essential | What it's for |
|---|---|
| Solar filter for the lens | Shooting the partial phases without frying the sensor |
| ISO 12312-2 glasses (one per person) | Watching the eclipse with the naked eye safely |
| Tripod | Stable framing; light drops fast during totality |
| Remote shutter release or phone app | Firing the shutter without touching or shaking the camera |
| Charged battery + a spare | You'll be shooting bursts for several minutes |
| Memory card with plenty of room | Bracketed sequences add up fast |
An honest heads-up about the kit 16-50mm: at 50mm, the Sun is a tiny dot in the frame — nothing like those full-frame corona shots you'll see online (those are shot with 400mm+ telephotos). It's not a flaw in your camera, it's just physics: if you want a large disc, you'll need borrowed reach or a teleconverter. If you don't have one, aim for Part 3 instead — the darkening landscape is a shot your kit lens can absolutely nail.
PART 2
Settings per phase (filter on)
Five phases, each with its own filter state, shutter speed, and bracket. Shoot all of it in Manual mode.
1 · Partial phase 🟢 FILTER ON
The Sun slowly loses a bite at a time. The longest phase — no rush here.
| Shutter | ISO | Aperture | Bracket |
|---|---|---|---|
| 1/500 s | 100 | f/8 | 3 shots @ 1 EV |
One shot (with its 3-frame bracket) every 5 minutes is plenty to document the growing bite out of the Sun. No need for a burst here — this phase lasts over an hour.
2 · Approaching totality 🔴 FILTER OFF — DO NOT LOOK AT THE SUN DIRECTLY
The last 20 seconds before darkness. This is where the most dramatic effects appear.
| Shutter | ISO | Aperture | Bracket |
|---|---|---|---|
| 1/500 s | 100 | f/8 | 9 shots @ 1 EV |
You'll see the diamond ring, Baily's beads (flashes through the Moon's valleys), and a first glimpse of the chromosphere. Remove the filter from the lens, but keep not looking directly at the Sun with the naked eye: through the camera, filter off, shoot in a maximum-speed burst — this moment passes in seconds.
3 · Totality 🔴 NO FILTER, NO GLASSES — ONLY SAFE MOMENT FOR THE NAKED EYE
The only phase where you can look directly at the eclipsed Sun with the naked eye, unprotected — for exactly as long as totality lasts, not a second more.
| Shutter | ISO | Aperture | Bracket |
|---|---|---|---|
| 1/15 s | 100 | f/8 | 9 shots @ 1 EV |
The solar corona — that pale halo you can only see during totality. Shoot in a maximum-speed burst for the whole duration — how long that lasts varies by exact location (check the duration for your specific spot, see Part 1). This is also the only moment you can look up with the naked eye without glasses.
Mental countdown: the instant the first sliver of light reappears (end of totality), glasses and filter go back on immediately — don't wait to "see a bit more."
4 · Leaving totality 🔴 FILTER OFF — DO NOT LOOK AT THE SUN DIRECTLY
The mirror image of phase 2, in reverse: the light comes back.
| Shutter | ISO | Aperture | Bracket |
|---|---|---|---|
| 1/500 s | 100 | f/8 | 9 shots @ 1 EV |
For up to 15 seconds after totality ends: Baily's beads, diamond ring, and chromosphere again, now from the opposite edge of the disc. Same maximum-speed burst as phase 2, and the instant it's over, the filter goes back on without any hesitation.
5 · Second partial phase 🟢 FILTER ON
The Sun gradually fills back in until it's whole again. Same settings as phase 1.
| Shutter | ISO | Aperture | Bracket |
|---|---|---|---|
| 1/500 s | 100 | f/8 | 3 shots @ 1 EV |
One shot every 5 minutes, filter always on. If the eclipse falls with the Sun very low — as the 2026 one in Spain did — the horizon may swallow the Sun before it's fully back; that's fine, you already have the important part.
Why bracket at all THE WHY
"9 shots @ 1 EV" means shooting 9 consecutive frames, each one stop apart, using the camera's automatic bracket mode (MENU → 📷 2 → Bracket). It does two things: it covers the corona's huge dynamic range (much brighter at the center than at the edges) so you can blend the frames later, and it gives you a safety margin if the "correct" exposure calculated in advance turns out to be a bit off.
A quirk for eclipses with the Sun very low, like the 2026 one in Spain: the light travels through much more atmosphere than it would at high noon (atmospheric extinction), arriving dimmer than these generic values assume. If your bracketed test shots all come out dark, don't hesitate to bump ISO up a stop or two from the table — that's exactly what the bracket margin is there for.
PART 3
The shot your 16-50mm can actually nail
No telephoto? Don't obsess over the solar disc. The other eclipse photo — the one almost nobody gets right — works better wide.
The eclipse in the landscape WIDE ANGLE · 16mm
During totality, the sky suddenly darkens as if it were night, with an orange glow along the entire 360° horizon (the Moon's shadow has an edge, and you're standing right in it). At 16mm, with people or landscape in the foreground and that darkened sky behind, you get a shot no telephoto can capture. Starting point: f/4 · ISO 800-1600 · whatever shutter speed the meter suggests for the sky — this is a "sudden nightfall" shot, not a portrait of the disc.
Mission: plan an interesting foreground (people looking up, a monument, a tree) to frame against the darkened sky. Practice the composition during daytime before the event, without pointing at the Sun.
Done when you have an eclipse photo that tells a story, not just a covered white dot.
PART 4
Practice run: rehearse with the Moon
There's no second take on eclipse day. Whatever you plan to do, test it first on something safe to photograph: the Moon.
Full dry run ANY CLEAR NIGHT BEFORE THE EVENT
On any night with a visible Moon: set up the tripod, frame the Moon, fire the 9-shot bracket @ 1 EV with the remote release, without touching the camera. Don't worry about matching the Sun's exact exposure — the goal is to prove you can trigger the bracket, frame quickly, and shoot without shaking before you have to do it for real with no second chance.
Autofocus can hunt on a low-contrast disc of light. Practice manual focus at infinity with peaking now, aimed at the Moon or a distant streetlight, and memorize exactly where the focus ring lands. On eclipse day, focus this way before the first partial phase starts, and don't touch it again.
Mission: a full rehearsal from start to finish — tripod, framing, manual focus, bracket, remote shutter — timed at under 2 minutes. That's roughly how long you'll actually have during totality.
Done when the rehearsal works without you checking this guide.
