It’s perhaps not a surprise that you’re going to get a crisper, sharper photo of the Moon on an evening at the coast. Sun just setting, Moon waxing gibbous heading towards Monday’s blood moon (which will be the last in the UK this decade, and there won’t be another here until 2021).
Here’s a shot I took at RSPB Snettisham on a chilly, windy, but sunny and bright evening (2019-01-17:16h02). Camera: Canon 6D with Sigma 150-600mm. Settings: 600mm, shutterspeed 1/2000s, aperture f/5.6, ISO 640.
