My main viewing location is set in the Chiltern Hills, about 30 miles from London.
It’s far enough away from major towns to have reasonable semi-rural light pollution and the site’s well screened with trees around. This has the benefit of cutting the ambient light from the neighbourhood at the cost of imposing a minimum altitude of about 15 degrees above the horizon for observations. Visibility is best in the arc running from the East to the South-West. Directly North is pretty good too.
