shooting the moon with a DSLR isn't idea, shutter shock, mirror slap are an

no they aren't.

electronic shutters in mirrorless cameras and higher-end DSLR's are
superior,

they're almost always mechanical.

using a telescope means a long focal length and any vibration
impacts the image.

there are these things called tripods.

You can reduce shock by delaying shutter action,
mirror-lockup, but most important is using the self-timer to fire the
shutter. Set it for 10 seconds, gives the telescope time to stop vibrating
from human touch.

what human touch?

use a remote control (possibly also with remote viewing), and with 10
second exposures, mirror slap is not an issue whatsoever.
