You are welcome. Hope it works for you . I went through the same learning curve, I even ran out and bought the Pyxis LE and ended up returning it just like you . It did work BUT between my OAG sticking out one side and my Filter Wheel sticking out the other side , I had to be super careful that it didn't hit or wires didn't get hung up when rotating . It was just not worth the hassle. Jared and others helped me and suggested getting one of those angle reading things and then a little light turned on in my thick skull!!
I have an old iphone so I was able to download a FREE App that reads angles, I just held the phone along side my Filter Wheel and guess what angle I got ?? 28 degrees !! The same angle I got when I plate solved an image I took. Now I knew my camera was at a 28 degree angle to the horizon. That is when I went back to the Mosaic Wizard and started messing with the slider . I figured instead of rotating the Camera to meet the angle suggested in SGP why not do the opposite ?? Rotate the IMAGE to meet the angle of the Camera !!! The only problem when doing mosaics is that you might end up shooting more panels than absolutely necessary because you were not able to get the full target framed perfectly within the minimum number of panels suggested by the Wizard. Sometimes you can eliminate panels if you keep messing with the overlap !!
With my very portable setup I can't afford to be that picky .
Good Luck and Clear Skies !!
