Likely underexposed... increase ISO and open up aperture to wide open to start...

Okay so last night I was simply trying to practice with my Intervalometer. I aimed it at the stars and did 30 30 second shots, 5 seconds apart at f/8 ISO 1250 bulb mode. Why are there no star trails? I was using the Canon EF 14mm 1:2.8 L that I mentioned in the OP and the EOS R. I wasn’t trying to have a nice scene or anything, just practicing with my new timer, but I figured I’d have at least some star trails at 30 seconds?
