Columbia University has released the first release (DR0) of the MDW hydrogen-alpha (Hα) Sky Survey, which is aimed to generate deep, high-resolution Hα images of the entire sky. The survey was founded by three New England-based friends and astrophotographers - David Mittelman, Dennis di Cicco, and Sean Walker (MDW) -with support from the Michele and David Mittelman Family Foundation.
