It isn't like anything you have seen before.

It's in stores now!

It's SolaREDi

Are you REDi?


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.

Designed to mount on the REAR of your existing telescope, the DayStar design is adaptable to a wide variety of astronomical telescope systems.

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.

DayStar ultra-narrow bandpass filters are available in half-bandwidth as wide as 10Å or as narrow as 0.2Å in the following wavelengths:

  • Hydrogen Alpha
  • Calcium H and K Line
  • Sodium D Line
  • custom wavelengths available upon request.

Take a look at DayStar Filters.  You will like what you see.
