Below is a picture of the German Equatorial mount that comes with my Meade Polaris 130 telescope.
Starting from the left side of the picture, the first red arrow (1) is pointing to a large allen screw. What does this allen screw do/adjust?
Red arrow 2 is pointing to an indicator, and to the right of the indicator is a thumb screw. I know that the thumb screw must be loosened in order to set the RA as pointed to by the big RA painted in white of the top of the gear housing. I know how to use basic setting circles, but what is this little silver pointer for, and how is it used?
The third red arrow is pointing to a recessed small allen screw. What does this allen screw do/adjust?
I am asking these questions because I want to know about my mount. Secondly, when the scope is all put together and balanced, the worm gear for the RA is too stiff.
