Solar Images with Solex and Sawtooth effect

Imaging the sun in the morning of september 14, 2024. I'm having some issues with sawtooth effect on the edges of the sun. The cause could be the mount scanning performance and/or turbulences. The figure out what the cause is, I used my bigger EQ8 mount. As a first conclusion: the sawtooth effect is much lower but on the other hand, the seeing was very good. This work will be continued. 

Below images of the Sun in H-alpha, H-beta and CaII H.
