For those we MX or ME when you are training PEC

Where are you pointing your OTA ? From the instructions it looks like we shoudl have dec close to zero and a star within 5 or 10 degrees from Meridean ?

Is this what you do ? I assume you dont want star to cross the merdean while logging data ?

Also the instructions say to orient camera so X = RA

Question i have is what is X relative to ? My CCD is rectangular. So shoudl X axis be across the long side ? Or do they mean x axis relative to the imaging software ie X axis is horizontal when looking at screen ?

In CCD soft my rectangular camera image is allways shown in Portrait mode. Ie longer side vertical in Y axis.

So do I irent camera to move star up and down the long axis when I move RA or sideways left to right on short side of rectangle when I move RA ?

Seems to be important to ensure DEC drift is not captured and only RA PE is captured.
