These filters (mostly our Lumicon Brand) are intended for visual use while our Astrodon filters are designed for Astrophotography. Some of them have similar names (OIII or Hα, for example) but the Lumicon visual filters will have a much broader bandpass making them useful for visual use, while a narrowband Astrodon astrophotography filter would not pass enough light for visual use.

Lumicon visual filters can still be used for casual astrophotography.
