I was central in this map (yellow area) looking NNW towards the darker orange of Newbury.
For my first attempt I had drivenwest into the smudgy green area.
Maybe you can guage the relative 'darkenss' for you own location relating it to my location and my image.
105mm is a good FL. I might try the 138/2.8 next time. 180/2.8 was a bit long given the lack of perspective from my back garden.
