The image was soft, mobile and impossible to focus.
I persisted until later and things settled a little.

Outstanding, especially the 'river' in the first image. Any idea what this structure is? Looks like a horizontal effect but that might just be the imaging angle.

The "river" is a filament, it is the plan view of a prominence which will show as an arch if it lasts long enough to reach the limb of the Sun.     🙂

Thanks. :thumbsup:

The seeing conditions were awful!  The sky was white around the sun.
The image was shaking on the monitor at various frequencies.
Only the clever software pulled the detail from the mush.
