MDW Hydrogen-Alpha Sky Survey

The MDW Hydrogen-Alpha Sky Survey (MDW Survey for short) is an ongoing project to create a deep, high-resolution, H-alpha image of the entire night sky. The project is being undertaken by three New England-based friends and astrophotographers – David Mittelman, Dennis di Cicco, and Sean Walker (MDW) – using a pair of remotely operated telescopes in New Mexico.
