H-alpha Solar Filters
The central part of the H-alpha filtering is the Fabry-Pérot interferometer. Unlike the Etalon, this filter is adjustable and can be variably set to a ZWL. This gives more flexibility for different object and detail observations.

Filters with 0.3Å ångström bandwidths will reveal superior surface contrast above any other filter.
Filters with 0.4 ångström bandwidths will reveal excellent surface contrast as well as fine chromosphere detail.
Filters with 0.5 ångström bandwidths will reveal better surface contrast as well as great prominences.
Filters with 0.6 ångström bandwidths will reveal some surface contrast as well as prominences.
Filters with 0.7 ångström bandwidths will reveal prominences in high contrast and occasionally, surface texture.
PE Filters with 0.8 ångström bandwidths will reveal prominences in high contrast.
Filters with 0.7~0.9 ångström bandwidths will reveal prominences in high contrast.
