Recently bought myself an ONSTEP system for guiding. And finally, after 4 unsuccessful observation attempts, everything worked. On exposures longer than two minutes, the stars get smeared. Also updated the aperture on the main mirror, as the previous one was made of cardboard and uneven. Due to the curfew, I shot on April 14, 15, 16, and 20. Full calibration.

Now we need to adjust the inter-frame shifts, and it will be even better!
