Doonvarra Head Observatory

A dark-sky observatory on the west coast of Ireland, for twelve guests at a time.

You’re probably reading this with the lights on. We’ll come back to that.

Orla Breen

“I spent eleven years telling people what the sky would do. Now I show them what it’s for.”

Orla was a weather forecaster for eleven years, reading the sky for other people. She chose this headland for its darkness before she owned a telescope.

On her best night here she measured 21.8 on a sky quality meter. At that darkness the Milky Way is not a haze: you can see the dark lanes in it with your own eyes.

She runs every night herself. She is the only person behind the observatory, and she is the one who will meet you in the car park.

At 4pm, Orla checks the sky.

Cloud is the part everyone asks about. Orla spent eleven years forecasting it.

4pm
On the day of every session, Orla checks the forecast.
By 5pm
If cloud is forecast, she emails everyone booked. You choose: move to another night, or a full refund.
On the night
If the sky closes after you’ve arrived, your second visit is free.
Never
A talk indoors instead. “If there’s nothing to see, I’d rather you went home warm and came back.”
Doonvarra Head under full cloud at dusk: no stars, the dome closed, three telescopes and deckchairs on the lawn, the lookout beside the dome. The same headland from the same spot on a clear night: guests walking the red-lit path towards the dome under a sky full of stars.
The same headland from the same spot. First under full cloud at dusk, dome shut. Then a clear night: a long exposure, so it shows far more stars than your eye will.

“Cloud is the only guest who never cancels.”

Which is why she’ll move your booking rather than show you a grey sky and call it an experience. “I will never sell you a cloudy night.” Book a sky night

Right. Lights off.

“Give your eyes twenty minutes and they’ll give you the Milky Way.”

Orla hands everyone a red torch and asks for phones to go on their dimmest red setting, or away. White light resets your eyes, and they take about twenty minutes to adjust again.

On the lawn, no telescope yet.

  1. 00 Only the brightest stars so far.
  2. 03 Orla’s green laser starts pointing.
  3. 08 More stars than you guessed were there.
  4. 12 A pale band, dark lanes: the Milky Way.
  5. 16 A faint smudge: another galaxy.
  6. 20 Your eyes are ready. Now the telescopes.

Drawn, not photographed: roughly what a dark-adapted eye picks out.

What your eye will actually see

The honest part. Photographs of the Milky Way, including the ones on this page, are long exposures. They show more stars and much more colour than any eye gets.

What a camera collects. A long exposure, gathering light for far longer than your eye can.

Nearer what you’ll see. The same photograph with the colour taken out. To the eye, the Milky Way is a pale, textured band with dark lanes in it. Still fewer stars than this.

2.5 million years

Here is why the real thing is more interesting anyway.

The Andromeda Galaxy is 2.5 million light-years away. Once your eyes have adjusted, you can see it without a telescope, as a faint smudge. Honestly, a smudge. But the light landing in your eye left it 2.5 million years ago.

The view through the eyepiece: Saturn small and sharp in a black field, its rings visible, two moons as points of light.

Small. Sharp. Ringed.

This is Saturn through the telescope, as the eye really sees it: small in a black field, the rings clear, two moons as points of light. This one is true to the eye. It is small, and it is unmistakably Saturn.

Saturn is up in autumn and early winter.

Often seen, depending on the season and the sky

Orla chooses on the night.

The Milky Way
Across the whole sky over the sea. Best in autumn.
The Andromeda Galaxy
Another galaxy, 2.5 million light-years away. A faint smudge to the eye alone.
Saturn and its rings
Autumn and early winter.
The Orion Nebula
A cloud where stars are forming. Winter.
The Pleiades
A cluster of young stars. Through the winter.

Plain facts, with the lights on

You’ll plan this at home. Here’s everything, plainly.

When
Late August to mid-May, Thursday to Saturday. About two hours, starting after full darkness.
Start times
In late August the first sessions start at 22:30. In midwinter, at 19:00. Nights are best without the moon, so the calendar follows it.
Price
€35 for adults. €18 for under-16s. Children aged 8 and over are welcome.
Booking
Online, for a named night. Booking for each month opens on the first of the month before.
Bring
More warm layers than you think. It is a headland in the Atlantic, and it is colder at night than it looks from the car.
Access
The path from the car park is level and 150 metres long. One telescope has a low eyepiece that can be used from a chair.
Changing your night
Move your booking free up to 24 hours before. Inside 24 hours, it can still be moved if another guest takes your place.
Closed
Mid-May to the end of July. At this latitude the sky never gets fully dark then: even at midnight, twilight hangs on the northern horizon.

Questions

hello@doonvarra.ie

Orla answers every email herself.

A sky night, in order

About two hours, starting after full darkness. Twelve guests at most. Orla meets you in the car park.

The dome at night with its slit open and red light at the door, the path of low red lights leading to it, the old coastguard lookout beside it.

The path

150 metres from the car park, level, edged with low red lights. Long exposure.

Guests in deckchairs on the viewing lawn with red torches, three telescopes in a row, the dome and the lookout, under the Milky Way.

The lawn

Deckchairs and blankets between three telescopes. The sea on three sides. Long exposure.

A gloved hand focusing a telescope eyepiece in red light, the dome behind.

The eyepiece

The 14-inch reflector in the dome, and the three on the lawn. On a still night you can hear the sea below the cliff.

A basket of woollen hats, a flask and two mugs of tea on the lawn, lit by a red torch.

Tea

Tea, hot chocolate and a basket of woollen hats. Take one.

“The dark here is the most valuable thing I own. I’d like to lend it to you for a night.”
