The LS50 filter is engineered to deliver high-contrast views of the Sun, with a bandpass of less than 0.70 Angstroms. This narrow bandpass allows you to observe both surface features and edge details, such as solar prominences, with impressive clarity. For those seeking even finer detail or higher resolution for imaging, an additional etalon can be added to reduce the bandpass to approximately 0.50 Angstroms, depending on the telescope used.
