Looking for R5 Astro lens

Hi - I am a relative newbie to astro photography. I've done a little with my Canon 5D3 and 24-105 f4.
I recently got a Canon R5 with 24 to 105 f4.
Can someone recommend a few lenses to look at for astro photography with the R5? I'm assuming that the 24-105 f4 isn't fast enough.
Thanks...

I am enjoying the Irix 15 f2.4 firefly. It is a manual focus but has an excellent "click" at infinity that really helps with astro photography. Affordable and good quality.

An f/4 lens is more than adequate with a tracking mount and longer exposures.

However, there are probably a few good manual f/1.4-f/2.8 lens available.
