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.ELETTRONICOenCharacterization of the Solar H-alpha Spectrum Using Lunt 50 mm Telescope with Pressure TuningTechnical reporthttps://doi.org/10.20371/INAF/TechRep/381
