Abstract (from CDS):

The Mittelman-di Cicco-Walker (MDW) Hα Sky Survey is an autonomously operated and ongoing all-sky imaging survey in the narrowband Hα wavelength. The survey was founded by amateur astronomers and is presented here in its first stage of refinement for rigorous scientific use. Each field is exposed through an Hα filter with a 3 nm bandwidth for a total of 4 hr, with a pixel scale of 3.″2. Here, we introduce the first Data Release of the MDW Hα Survey (Data Release 0, or DR0), spanning 238 fields in the region of Orion (∼3100 deg2). DR0 includes: calibrated mean fields, star-removed mean fields, a point-source catalog matched to Data Release 1 of the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS1) and the Isaac Newton Telescope Galactic Plane Survey (IGAPS), and mosaics.
