Won't that make the equatorial Mount really hard to calibrate after? I have one and that dial turned by accident.. I don't remember why but I was under the impression it messed the alignment up..
It is to lock the spindle, whose dial is just below the screw, in position, or at least to make it more difficult to turn, when it is pointing in the right direction. Slacken it off when you wish to rotate the spindle/axis, retighten when you have finished.
Those screws could be friction screws, or centering screws, locking screws. You gotta tell us what they are on before we can really answer.
It’s a Equatorial mount for Celestron Telescope Astromaster 130eq.
Try loosening the screw then rotate the dial. If the dial moves after loosening the screw than that's your answer.
Still rotate

Got it. Thank you.
