Workshop on Young Crescent Moon: Visibility Limit and Digital Image Contrast

The Institut Teknologi Bandung’s Astronomy Research Group hosted a workshop centered on understanding the young crescent moon (Hilal) phenomenon in Islamic astronomy. The primary focus was disseminating cutting-edge research, particularly a methodology for measuring digital image contrast to determine the young crescent’s visibility threshold. Participants included lecturers from Islamic Universities, private observatory administrators/observers, and astronomy enthusiasts. The workshop covered image processing fundamentals, hands-on activities involving digital image capture, and practical use of AstroImageJ software. Comprehensive feedback assessment measured its effectiveness. Additionally, the workshop aimed to promote research relevant to Islamic religious practices and introduce prospective students to Astronomy master’s and doctoral programs, fostering a crucial link between research and education in Islamic astronomy.
