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

Hi Kevin
Very impressed with the detail and focus.
How difficult and costly is it to do the PST Mod -stage 1 and 2 ???
If you could point me in the right direction I would be very grateful.

Peter VV.
I came close to buying a PST this summer but didn’t have time to look around at prices after all. Probably just as well considering I haven’t actually even looked through one yet!
Your images are really great, really dynamic. Can I ask when you are actually looking through the scope, which of these images comes closest to what you actually see by eye? I have a Baader filter for my Dob and am impressed by the detail I can see with that – but of course, no prominences visible there. really must find someone with one and take a look. I live in Greece so we generally get quite a bit of sun but guaranteed it will be cloudy if I buy!
The red DSLR images on this page http://www.photosbykev.com/wordpress/photography/pst-solar-imaging/ will give you a reasonable idea of the typical images you see visually.
regards
Kev
As normal, a great set of images!
