I would choose autoguider with phd with exposures of frames of at least 3 secs , however I'd recommend going the PEMPRO way

Hi all,

If I wanted to do PEC (or PEM as the manual says) training for my Mach1, the manual has two methods. I have a high magnification double lined illuminated eyepiece, and also an Orion Starshoot autougider which I use PHD for.

What would be the preferred method of doing PEC training? Should I use the eyepiece or use the autoguider with PHD? Or am I missing something?
