As we now know, there is another thread. @AlienFTM, depends on how far you want to travel. I live a short drive from you, north of the (currently unlit) M27 near Fareham. North to Wickham, and over towards the Forest of Bere, it is quite dark. For this part of the world, amazingly so.At Beaulieu last year, evicted from house while new central heating pipework went in, we visited the SOE museum there. On display was a Luftwaffe map of Southampton from about 1940, from a downed bomber. First thing I did was look for our house (even though our neighbour, when we moved in in the 80s, told how when the estate was built on the site of a pig farm in the 60s).
The now main road through the estate was clearly the 1940 town boundary. It was all fields beyond (mercifully the first few acres remain a sports field. We're separated from the sports field by a new link road to the M271). If only it were ever thus. But no, they're filling in the gaps between us and the M27 with ever more housing. Sooner we move somewhere dark, the better.
The flight path for the airport has also calmed down a lot, helping daytime sky watching.
Short excursion, babies heads in the bv, followed by hot chocolate?
Most of the Solent city build is below the motorway, and we are just feeling the benefits of the hills for shielding light pollution.
Just as where you are, it will all be built on. But not for a while: enjoy it whilst you can.
I recommend it: it is not difficult to get into the sticks in Hampshire.
