No telescope. Fixed tripod. 24mm f/4.5 ISO6400 108 x 8s stacked = 14.4 minutes
This is with a wider angle lens: 24mm focal length.
I did this on a light-weight tripod on a windy night, just to prove that it could be done. I took 120 shots but on looking through them I could see evidence of the tripod wobbling in 12 of them, so I left those frames out of the stacking process.
As usual the camera has picked up so many stars that the constellations cannot be picked out. The next slide helps...
