Abstract

Abstract This study aims to analyze the implementation of astrophotography using the ZWO Seestar S50 with nebula objects in the development of Astronomy learning. The sub-questions examined include: (1) the implementation of astrophotography using the ZWO Seestar S50 with nebula objects in Astronomy learning, and (2) the role of nebulae as astrophotography subjects in supporting the development of Astronomy learning. This study uses a descriptive qualitative method. Data was obtained through direct observation of nebula objects using the ZWO Seestar S50 and documentation of the observation results. The collected data were then analyzed descriptively through the stages of data collection, processing, and interpretation. Research results show that the implementation of astrophotography using the ZWO Seestar S50 in astronomy learning is carried out through stages of instrument introduction, observation preparation, image capturing, nebula image processing, and the use of observation results as learning media. In addition, nebulae serve as astrophotography study objects that support the development of astronomy learning because they can visualize astronomical phenomena in a tangible way and strengthen the integration between science and Islamic values. The implications of this research indicate that the use of smart telescope-based astrophotography can be an innovation in astronomy learning. Keywords: Astrophotography, Nebula, ZWO Seestar S50

Abstract

This study aims to examine the sharia legitimacy of the Isbat Session in determining the beginning of the lunar month in Indonesia through the perspective of the fiqh principle of Tasharruf al-Imam ‘ala al-Ra’iyyah Manutun bi al-Maslahah. The focus of the study is to analyze the normative basis of this principle as a basis for state authority and to test the effectiveness of its implementation in reconciling differences in hisab-rukyat and realizing the welfare of the people. The study uses empirical qualitative methods with content analysis and critical discourse analysis approaches. Primary data includes official documents from the Ministry of Religious Affairs regarding the results of the Isbat Session for the 2015–2025 period and public responses, while secondary data are sourced from fiqh literature, journals, and related books. The research findings indicate that the Isbat Session has strong sharia legitimacy based on the principle of tasharruf al-imam, where the state acts as ulil amri who ensures the realization of public welfare through collective decisions. Empirically, 82% of the Isbat Session decisions were successfully agreed upon by the government, NU, and Muhammadiyah, proving the forum's effectiveness as a unifying instrument. However, 18% of the differences that occurred—particularly with Muhammadiyah—were caused by fundamental methodological differences between rukyat bil fi'li (NU) and hisab wujudul hilal (Muhammadiyah). This study concludes that the Isbat Session is a form of Islamic jurisprudence that is valid according to sharia and effective in creating legal certainty and social stability, although further efforts are still needed to embrace the remaining methodological differences.
