DayStar Filters are the industry standard in narrow bandpass astronomical solar filters.  For decades, professional observatories and universities worldwide have counted on the superior quality and performance of DayStar filters.  They can be found in the world's major educational institutions and research facilities, both terrestrial and flown.

DayStar's unique technology achieves narrower bandpasses for more a more detailed image.  Combined, these design differences accomplish the highest quality view in contrast and resolution possible, limited only by seeing or diffraction.
