What makes Mackinac Island good for astrophotography?
Mackinac Island in the Straits of Mackinac between Lake Michigan and Lake Huron bans motor vehicles, which eliminates headlight interference and keeps the island's artificial light sources to a minimum. The surrounding water on all sides means four open, dark horizons with no terrestrial light for miles in most directions. The island's Victorian architecture and historic fort provide unusual night foreground options rarely available at typical dark sky sites. It's Bortle Class 3 to 4, modest by rural western standards, but exceptional for a populated island destination accessible by ferry.
When is the Milky Way visible at Mackinac Island?
The galactic core is visible from April through October. The island is seasonal: most businesses and ferry service operate from May through October. The core is low in the southern sky due to latitude but is visible above the Straits from the south-facing areas of the island. Aurora photography is the stronger draw here: the island's northern latitude puts it within reach of significant geomagnetic events several times per year, and the open water to the north provides a dark reflection canvas.
