The focuser is a rack-and-pinion, which works well with any 1.25” eyepiece. It is smooth and feels sturdy.
The mount is solid and the turning motion feels smooth. It moves up, down, left and right which is as simple as it gets with telescope mounts.
Overall Orion FunScope 76 is a cheap and fun way to start out with astronomy. Of course, you shouldn’t expect something that you will use for 50 years. But it is a nice beginning to an astronomy journey, especially for kids.
