In recent years, the science of astronomy has gone beyond the lessons covered in schools and become a learning domain that people promote with new experiences in line with their individual curiosity, which has paved the way for astronomy learning methods to diversify and attract attention with the contribution of technology. Augmented Reality (AR) applications, which have been encountered in many fields including education in recent years, are also actively used in the astronomy learning process. Star Walk 2 is one of these AR applications, which enables individuals to acquire real-time images and information flow while observing the sky, and includes features to promote astronomy learning for individuals of all ages. There are some elements with significant effects on individuals in preferring these applications, and these are language preferences, user-friendliness and accessibility. Star Walk 2 application can meet users' needs in terms of accessibility and user-friendliness. However, it lacks a detailed guide and language options in Turkish. This situation is likely to prevent users, whose primary language preference is Turkish, from making effective use of the application. In this context, the purpose of this study is to provide a detailed Turkish guide on the use of Star Walk 2 application for students, teachers and other individual learners. Within the scope of the study, the researchers have used all the features of the application and analyzed the observations enabled. They have prepared a detailed guide by examining the paid and free versions of the application separately. With the visual-aided guide prepared, it is aimed to enable users' effective use of the application features and to facilitate their astronomy learning process. In addition, it is envisaged to provide Turkish user guide support to users who cannot use the application due to language options. It is believed that the guide and observation details about the application presented in the study will be a useful resource for both students and teachers, and individual users.
