Hi Gavin.

Apart from focus, the brighter stars appear over exposed, too big and merge together, particularly near the brighter areas of the image.

EDIT: I read your Helix post - camera is an ASI071MC - APS-C colour CMOS

Balancing read noise and saturation is tricky. A combination of slowing the exposure down / or less exposure time and dithering to handle noise. A 10 - 15 pixel dither is a good value between images - if your gear supports it.
