What resolution do you get?

I'm researching a book on digital spectroheliographs and would like to know what spatial resolution amateurs are obtaining with today's telescopes and cameras.
Obviously the seeing conditions and pixel size are important factors.
If you have any images which demonstrate a good resolution, I'd love to see them and hear your comments.
(Resolutions <1" arc is where it gets interesting)
Thanks.
