The photographs below show the sun in the Hydrogen-alpha (H-a) bandwidth using a PST Stage 2 Lyra Optic 4″ f/11 refractor modified for H-a imaging captured with DMK41 and DMK21 mono CCD cameras and sometimes a 2.5x Powermate for the closeup detail.

The development of the Lyra Optic 4″ f/11 H-a Solarscope can be seen here
