Dark Skies of the Tywi Valley, Carmarthenshire

October 1, 2016 Leave a comment

We stayed at a remote cottage in the Tywi Valley north west of Rhandirmwyn in Carmarthenshire for a week and I had a couple of opportunities to spend some time under the dark skies available here. To the naked eye there is no light pollution at all within the Tywi valley and the Milky Way is easily seen when your eyesight is dark adapted. The higher sensitivity of the camera sensor picks up some light glow from Rhandirmwyn village and a larger amount from the town of Llandovery, which lies some 10km distant. The area is well known for dark skies with a couple of sites recommended here Dark Sky Discovery Sites UK including the YHA hostels at Ty’n-y-cornel and Dolgoch located to the north of the Llyn Brianne reservoir.

Here are some photos taken from the cottage on clear, but occasionally cloudy, nights with the Fuji X100s at 28mm, F2, ISO 6400, 15 – 25 second exposures.

The Dark Skies of Anglesey, North Wales

March 11, 2016 Leave a comment

Spent a few days up on Anglesey near Penmon where they have stunning dark skies so I took the opportunity to do a little astrophotography from the back garden of the cottage, which overlooked the sea to the north. Orion was prominent in the western sky while to the south Jupiter was rising above the roof and through the trees. Many star clusters were visible with the naked eye including the Double Cluster, three clusters in the southern half of Auriga and M44 (The Beehive) near Gemini. The Andromeda Galaxy was easy to find in the north.

The Isle of Anglesey AONB is currently working towards gaining Dark Sky Reserve Status and you can follow their progress here The view was quite spectacular on a moonless night with stars from horizon to horizon. Light pollution was minimal for naked eye viewing, particularly to the north and west. The main problem for photographers will be the large number of passenger jets heading east – west in the north and it was difficult to take a photo which did not have a plane trail in it.

All images taken with the Sony RX100, F1.8, 28mm, ISO 3200, 8 second exposures.
