If you enable the mount limits and you slew the mount pass that point, the mount will stop as expected.
However, it is no longer possible to issue a direct "Slew to home position".
The "Slew to home position" command which in theory sends the mount back to the home position (let's assume for argument sake, that the mount is counterweight down, OTA pointing straight up at Polaris) should bypass the mount limits.
This might be also a problem for Park, which I need to test, but I assume we will be facing the same situation
It's not just to home. I have a request out there somewhere that asked for mount limits to be avoided on any slew that would otherwise pass through them. I use eqmod, so any mounts, not just CEM* either.
There are no issues as such, enabling the mount limits and right click on the map and slew to a target outside the limits will not move the mount. A pop-up message will appear.
