Characterization of the Solar H-alpha Spectrum Using Lunt 50 mm Telescope with Pressure Tuning

In this work we present the study of the Lunt LS50 Hα telescope equipped with a CMOS QHY5LII-C camera and the capability of reconstructing the solar spectrum through full-disk images of the Sun at different pressure tuning steps of the telescope. Furthermore, specific solar regions and structures were analyzed to obtain a profile comparable to the expected Hα spectrum. This allows us to investigate important physical parameters, such as temperature and height of the studied structures.
