The only “smart” feature that I find useful is an equatorial gear/mechanism. It turns your telescope with the rotation of the earth (or fancier ones can be set to turn with the earth plus another movement so you can track objects like the moon). Just look for that.

Camera mounts, specific lens, and filters can be great additions. None of those things are “smart.” Here’s a photo I got of the lunar eclipse the other night. I didn’t use an equatorial mount or filters because I was rushing and didn’t want to set it all up, just a camera mount, so I apologize for the quality.
