DayStar Filters

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.

The DayStar SolaREDi alpha is a multi-functional, ready to use dedicated hydrogen alpha solar telescope. The SolaREDi H-Alpha telescope combines performance, refinement and sophistication that will dazzle any user. OPT carries the entry-level DayStar 0.7A Hepta Alpha Solar Telescope, the DayStar 0.5A Penta Alpha Solar Telescope, and the amazing DayStar 0.3A Tria Alpha Solar Telescope in stock!

Check out two of the latest developments from DayStar. The first is the Energy Rejection Filter. A DayStar ERF, or energy rejection filter, must cover the front objective of any telescope using rear-mounted DayStar T-Scanners or Quantum H-alpha filters. ERF's reduce the heat load on your filter assembly by absorbing or reflecting UV and/or I light and transmitting light in the desired visual spectrum. The second is the DayStar Quantum Hydrogen-Alpha Solar Filter. It 's a Quantum Standard Edition Hydrogen-Alpha Filter with completely redesigned, precision-heated housing that incorporates ALL of the desired features for today's solar observer or researcher... and then some. Operation couldn't be simpler, just plug it in and a green light indicates when the filter is onband. More clever innovations from DayStar!
