- Without any contrast enhancement, and give a very good idea of the planetary contrast improvement that is seen visually.
- The high quality of filters permits stacking with no image degradation.
- It's improved supression of chromatic aberrations for astrophotography applications.
- The filter leaves natural colors mostly intact, but significantly enhanced.
- The filter brings an entirely unique approach to planetary contrast enhancement and light pollution reduction.
