HI Alan, and welcome to CloudyNights!
If we start with your telescope and mount oriented as shown in your picture, with the telescope pointed toward Polaris. And if you want to point the telescope at something above your southern horizon, the following is one way of getting there:
Lock the Declination axis. Then, gently holding the telescope tube, loosen the RA axis lock just enough to permit the telescope to move in RA. Now move the telescope in RA either toward or away from the camera (based on your photo), until the counterweight shaft is parallel to the ground. Now lock the RA axis and while holding the telescope tube, loosen the Declination axis enough to permit movement in Declination. Now move the telescope in Declination, through your zenith, toward your southern horizon. Tighten the Declination axis once the telescope is pointed as high as you want it to be pointed above your south horizon.
Now you may have noticed that your eyepiece and/or finder are in awkward positions to use. That can be remedied by loosening the cradle around the telescope and rotating the telescope within it, then tightening it down again.
To point the telescope at specific objects above your southern horizon, you'll want to make further adjustments in RA and Declination. Just keep in mind that movements in Declination move the telescope toward or away from the north celestial pole, while movements in RA will move the telescope east or west along a curved line of constant Declination.
It will help to use star charts that show lines of RA and Declination, preferrably on a fairly large scale (showing large areas of sky) until you get the hang of how an equatorial mount works.
An equatorial mount takes time to learn, but once one fully adjusts to them, they become very easy, natural, and convenient to use. It's this initial learning phase where all the problems lie!
Different explanations work better for different people, so I would suggest reading as much as you can about the function and use of an equatorial mount -- and of course, practice a lot with the one you have. Don't be too concerned if some of the explanations don't make sense. At some point everything will "click" into place -- all will make sense -- and you might even end up wondering how something so easy (once you've learned it) seemed to be so complicated (prior to learning it).
