The South Coast from Bognor to Seaford is awash with light...there is a nice gap from Seaford Head until Eastbourne Town! As a historical note that is just where my father was set up for a while during WW2 when he was operating seachlights and one of the local astronomers uses the Seaford area for a "Dark Sky Site".
The current pratical problem here is not so much "Light Pollution" but "Heavy Cloud Pollution"!

I'm not far from the limestone Dales Mike. From my location we can seen the prominent hills Ingleborough and Whernside. The last of the trio, Penyghent, would be visible too, but it's obscured by Pendle Hill.
Four winters ago, we spent a few days at the village of Malham with a 60mm spotter. It was surprising how dark the sky was in the vicinity. The winter constellations were very conspicuous, a rare sight these days.

Nice bright day today 14C or 15C.
5/8 cloud 4,000ft and 25,000ft. 1029 hPa.

Took the bull by the horns. Maybe not wise at my age.

The mag minus 16.5 LED lamp is angled down to only mag minus 12.

However, a second lamp was installed. Only mag minus 15.5.

Passing the building I saw 2 slim young men concreting the whole back garden after doing the same to the front. Instead of grass we have dug out basements and vast areas of concrete. And they wonder why flooding occurs.

I asked them if they could angle the lamp down, also using hand signals. One understood and said O.K.
10 minutes later when I came back I see it has moved, maybe not as angled as the other. Probably mag minus 13 now. I'll see tonight.

Ain't life grand.
