Im assuming you are Polar???
The scope has settable min and max elevation limits.
These are relative to the scopes base, not the horizon, and are designed to prevent equipment clashes.
In AltAz, there is normally no problem, but in Polar, trying to goto objects that have a large positive DEC, ( even tho visible ) means the scope must slew to a large -ve "elevation"
