I think, it's a lot to do with computer technology, sensors, auto compensate for mechanical errors, tracking, backlash, even on a cheaper made mounts.
Cheaper digital cameras have anti shake compensation now days too.


Not an astrophotographer, I see. Image stabilization is built into lenses, not cameras. It is intended to be switched off when the camera is on a tripod.


Well, tell it to Sony, Olympus (best stabilization of any camera) and Pentax, they all have it in-camera. Also, you don't need to turn off stabilization on the tripod now, it won't impact it the way it did in the past. Also, Pentax has astronomical object tracking incorporated into their cameras and it is effective to a point, though not yet as good as a good mounting tracking.

A user of only Canon and/or Nikon digital cameras I see - they do
indeed have image stabilization in the lenses. Other brands can have
image stabilization in the camera bodies instead. Finally, a camera
must include both the camera body and a lens - if either is missing,
you won't be able to capture any images. Also note that a
photographer says "lens" even when the image forming element is one
or several mirrors.

I said, digital cameras has anti shake, in general. of course it's

built into lenses.

Not of course - some cameras have their image stabilization in the
camera bodies instead.
