Interesting info thanks Valery. I was having a read over my coffee earlier this morning. Let's give a few days here so people get a chance to see it then i'll move to the library as is a useful resource.

This shows us that even with amateur level H-a filters we can ivestigate such an interesting feature of the sun like spiculaes.
We need 6" and up telescopes, 0,5A or narrower etalons and a speedy low noise and high QE cameras.

A very detailed article Valery...I need to get some time to read it more thoroughly though.

Thanks for posting,

Valery,
One issue it the ability to accurately tune the filter into the wings, at known and repeatable wavelength off set.
With a Spectroheliograph this is much easier and more accurate.

Thanks for this Valery,
Indeed, many of the papers based on observations made at the SST are very interesting for amateurs like us.
