Finally getting the etalon tuned more to my liking and I am reasonably pleased with this image and level of detail.
Some nice active regions in view with lots of magnetic field lines to be seen. Filaments are quite interesting too.
On the limb is quite a few nice prominences with a lovely hedge row at the top of the image.
I am trialling not doing a proms run, but seeing must be good to get the most detail. As you can see the proms look a little blurred and that is due to the seeing.

I got a bit done today, that filament ran right to your hedgerow. Stunning.

This is a good photo for explaining what you actually see through the LS80 DSII with good seeing.
That's about the level of detail you see on mottles and fibrils, if that's what they're called. They are a little more obvious in the photo, but you get slightly finer detail visually if seeing is good. I found that noticing the magnetic structure required practice. Things that I did not notice at all for the first months are obvious to me now when I look through.
The brighter areas (plage?) look a little better visually. And proms are sharper to naked eye than shown in the photo (I know that it was caused by imperfect seeing when this photo was taken).
(I think if you had done the same processing on an image taken during perfect seeing, then the proms would be about right, but the surface would be better than you can see visually.)
