Doh!
TIL that my Astroberry was 32Bit - no wonder kstars did not update past 3.6.0.
I just reinstalled raspbian 64Bit and updated everything to the latest revision. I took it out last night to try it out and everything worked flawlessly.

I captured the Elephant Trunk Nebula in SHO, got around 2h of data for each filter (Antlia Ha OIII Dualband + Antlia SII). This is my result:

Pretty happy for the first light. Hoping to have some clear nights to come for further testing.

Gear used:
Raspberry Pi 4 (Raspbian, kstars)
Skywatcher ESPRIT 100ED
0,79x Reducer/Flattener
Skywatcher HEQ 5 Pro (Belt mod)

I had no problems guiding with 2sec exposures, even with the 3nm SII filter. I stayed in the 0.5~0.6" rms error range most of the time.
