Hi,
A few times I was pointing the telescope at zenith manually using the arrows in Asiair, I've noticed that when the scope is pointed at zenith, and then I think I use the left or right arrow (to make it go up), it makes some weird sound, not sure how to describe it. It happens only when using one of the arrows. Ehh my english... :p
I've recorded a quick video:

Is this something I should be worried about?
Thanks
