First Class H-alpha Solar Filters by SolarSpectrum

A SolarSpectrum filter transforms almost any telescope into a high-end H-α telescope with appropriate accessories. The filter design is optimized for observatories and amateurs who want to use the full aperture and resolution of large telescopes for solar observation and plan more than just an occasional view at H-alpha.


The filters have no central obstruction and are actively heated. This means that the filter does not need to be readjusted during the course of the day - ideal for long-term observations, time-lapse photography or public relations work.
