Went to Iceland to see the nothern lights with my wife and check a bucket list item off, and got very lucky the first night. It was cloudy every other night the rest of the week but at least we got to see them! The A7RII may not be the best long exposure/astro/night camera on the planet, but it can still deliver. A7RII, Batis 18mm, I think ISO 1000 for 15 seconds.
