Carina with Easter Stars

I've been experimenting with a Startravel 120/600 for narrowband, for fun.
Ordinarily one might be disappointed by cruciform stars (top left is worst) but hey it's good Friday

Just combination, DBE, SPCC, STF stretch, starless, removed most of the green from the stars, quick histogram tweak to bring down the background a touch (100px clipped), rescreen.

BX really highlights the astigmatism (2nd).
The top left crop shows it better (3rd)

I would love some pointers on how to fix the stars?

About 5hrs of 300s & 600s in SHO

SW 120/600 + orion flattener
ASI160MM + Antlia 3nm SHO
CEM40EC (0.21" total )

NIINA + PI

Peace Love & Mung beans.
