A stream winds its way to the stream over this beach in Co. Sligo.

The Gweebarra River flows into Gweebarra Bay and then into the Atlantic. It meanders through a series of sand banks and has wonderful turquoise waters. Seen here from directly above as the tide is just about to completely cover the last of one of the larger sand banks.

Made in the Dark Sky Reserve in southwest Kerry, this shows the lunar eclipse of 2015 near totality. The blue glow in the water is bioluminescent plankton.

Noctilucent clouds are a rare sight. Only visible when the sun is below the horizon, they are the highest altitude clouds on earth, right on the edge of space. One evening in June 2014, there was a particularly beautiful display which I captured near my home in Ballingeary.

The Muglins lie about half a mile northeast of Dalkey Island, and are a danger to shipping. Many ships came to grief on these rocks until a light was established at around the turn of the 20th century.
This image was made on a very fine night, and shows the northeastern extent of Dalkey Island, with the Muglins light beyond. On the horizon, the Kish lighthouse winks at us.
This is one of the images that I'm most happy with. It is simple, but there is plenty for the eye to wander over and appreciate - most notably the line of clouds near the horizon and the fine detail in the Moon's reflection. The sea is slightly smoothed as it was a long exposure - perhaps 15 seconds or so.
This is the second image I've made of this location. Slightly earlier in the night than the first, and in almost identical weather conditions, it adds colour which I felt was lacking in the original.

Just after sunrise the eastern face of the Bull Rock is lit by the morning light. In this image the lighthouse and associated buildings can be seen, including the steps down to the landing, and the helipad. The unique gasworks building which was constructed right against the eastern cliff can also be made out, just above the natural tunnel that bores through the island.

Cúm na Léime (The Valley of the Leap) is a beautiful isolated valley near Bantry in Cork. The name derives from the local legend of a priest who made a miraculous nine-mile leap to escape pursuing soldiers from the ridge at the head of the valley. That ridge is known as the Priest's Leap (Léim an tSagairt).
This photograph looks north from the eastern side of the glen towards Léim an tSagairt, which is wreathed in mist. A rapidly changing morning, as I drove up the narrow road it looked like the mist might not clear at all, but clear it did and this is the result.
