At very cold temperatures, blocking filters may no longer work accurately central in the H-alpha wavelength, which means that the details on the sun become less visible.
Internal narrowband filters allow for a <2.4 Angstrom bandpass. Primarily an imaging system due to the difficulty of many to visually see everything that CaK has to offer. For telescopes up to 100 aperture and 1200mm focal lenght.
