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 a DMK41 mono CCD camera and sometimes a 2.5x Powermate for the closeup detail.
Solar images from January 2012, taken using the excellent Daves Solar System Recorder software (DSSR) which is now available as a beta release for public use.

The following images are taken with the PST Stage 2 modification, the system still needs tweaking but I’m pleased with the first light images
