Is the laowa 15mm f 2 zero d good for astrophotography?

Yes, I think it's a good pick for astro. The lens page calls it a fast ultra-wide for astro, and f/2 gathers plenty of light for the Milky Way, while 15mm on full frame takes in a big slice of sky.

Two things to plan for. It's manual focus only, so you'll focus by hand on a bright star or a distant light. It also isn't stabilised, so a sturdy tripod matters. On APS-C it frames much tighter, so full frame is where it works best. If you're choosing a body, I'd start with the Sony a7 IV, Nikon Z6 II or Canon EOS R6 Mark II. You can see the full list of compatible cameras on the lens page.
