Electronic shutter on the Sony A7R II

I'm slowly started to understand how astrophotography is done, and apparently one takes thousands of pictures for selection and stacking.

Was thinking to use my DSLR's but the mechanical shutter on those cameras is limited to only 100K to 200K actuations. Probably also causing vibration of repeated use.

Till I get a telescope, could use some of my Canon or Nikon telephotos with a planetary/DSO camera, but those lenses are mainly AF with very short throw for precise adjustments.

Another option is the Sony A7R II using AF adapters or native FE lenses. While the shutter is rated for 500K, has the option to use electronic shutter in a silent mode which probably causes less stress to the camera over time.

But will the sensor or the electronics get damaged because of high electronic shutter count? Will rolling shutter be an issue? The A7R II apparently also has some star "eating" algorithms when +30s exposure are used, not sure if that will be a problem? Maybe the sensor will get burned by the sun even when using ND filters?
