Recently I build a full disk setup based on Quark. So I used this for H-alpha and normal teleoptics for white light during the eclipse. Processing is not perfect due to some issues, but you have to leave something for the rainy days too, right?

 

These are all taken with manual Alt-az mount with no tracking. Details via clicking the images (they also open a bit larger then). H-alpha setup details are in this link.

Beautiful photographs.
Your setup is great too.
So with 330mm focal length and the ASI174mm you can shoot the whole disk, good to know.
You don't have Newton's rings perhaps because you are also using a focal reducer.
Usually that optical element eliminates them, although not always.

Yep, with a reducer and some extra t2 extensions after the reducer one can fit the whole disk and protuberances in to the sensor.

 

I had Newton rings with my previous Quark setup (80/480 ota) even with the reducer. But I also had asi178mm then so it's hard to say where they manifested themselves.

A quick addition to this as I forgot to adjust the levels a bit and the area around the sun was blooming a bit too much for my taste.

And finally a very crude animation with only 9 frames. This shows at least some evolution of the protuberances. Note to myself: next time constant intervals and maybe a tracking mount... :D Click the image to open the video.

Very cool setup and very good photos.  To me animations are always great even if they don't capture any action they always show the changes in seeing conditions and equipment.  There is always something for me to see in an animation.
