Really no problem - look at the assorted small mount there are like the iOptron SkyGuider and SW Star Adventurer. They are in reality not guidable and people get good images - IF they put in the effort to set them up well.
Next come this urge to obtain a longer exposure then anyone else has managed. Really do get the idea that astrophotography is less about images and more about "I managed a single exposure of 28 hours 38 minutes, anyone beat that? Shame the sun wiped everything out but just look at the duration."
So if you do not want a guided system you have to accept that shorter exposure are the ONLY option. Trying for 10 seconds more because you think you might manage it results in failure. When you step over the limit the whole session is lost.
So not difficult, identify a mount that should track for your equipment and well set up for 60 seconds. Then take 60 second exposures. Not 80 sec or 90 sec but 60 sec!!!!!
