Seestar is not capable of directly capturing solar phenomena such as coronal rain, solar prominences, or coronal mass ejections (CME). These phenomena require specialized solar filters and equipment, especially H-alpha filters, to observe and image the sun safely.
The Seestar is primarily designed for deep-sky imaging, such as nebulae and galaxies. If you want to capture these solar details, it is recommended to use a dedicated solar observation telescope or add solar filters (like H-alpha filters) for imaging. Additionally, coronal mass ejections (CME) and other solar phenomena are typically observed through specialized solar satellites or solar telescopes, not regular astronomical telescopes.
If you are truly interested in solar observation, consider using a dedicated solar filter, but make sure that it is designed for safe solar observation.
