Sometimes, it would be nice to be able to loosen a go-to telescope's locks and move it by hand. It is a lot quicker to move a scope from one side of the sky to the other by hand than with the scope's motors. Unfortunately, all currently made go-to CATs lose alignment when they are moved by hand (the optical encoders that determine the telescope's position are part of the motor assemblies). If a motor is not turning, the computer does not know the telescope is moving. The only way to move a go-to scope "manually" without losing alignment is to use the directional buttons on the HC. That is no faster than a go-to but will allow finding objects the old-fashioned way, by star hopping.
