Quote:It is not useless if you have permanent setup.
Quote:I suppose that when you make the training this way you are trying to correct not only the periodic error but the erros in balancing, polar alignment and any occasional events like seeing and wind.
Quote:When you are not working with permanent setup next time you observe the balance and polar alignment will be at least slightly different as wel as the occasional events so if you play back the old corrections the result will not be good.
Quote:If you make the pec training with software and camera the results should be much better.
Quote:On my HEQ5/Sirius mount there is no permanent PEC. Always puzzling to me why most mounts don't seem to have this feature. I guess I need to buy a higher end mount?

Quote:I'm not too convinced PEC is much necessary with these mounts. Their errors are generally smooth and regular, and autoguiding is usually enough. If you do want PPEC, just get goin' with EQMOD. It's better than the HC in many other ways as well, and will also enable you to use Pempro.
