It's starting to look decent, but you're being too greedy with the gain—the stars are coming out as bloated disks. With this camera at these settings, the read noise is low and the full well capacity is also very small, so the stars are getting overexposed. Try shooting the same target at zero gain.
2. Give Siril a try.
