Astrophotography

Hello everyone,
I am trying to upgrade from d3200 to something more suitable for astrophotography, so far I am between two choices, d7500 and d750. Would you recommend these?

My budget is around €500 for the base.
And Idk what lenses are the best, I only have AF-S DX 18-55 VR and 35mm f/1.8
