So, plugging all the numbers into the appropriate formula... pixel size in micro-meters / focal length in milli-meters X 206.3

I come up with 1.22 arcseconds per pixel on my imaging rig, and 1.93 arcseconds per pixel on the guiding rig.

Does that sound about right? That is, does that seem like it might be an acceptable difference between the two?

Thanks,

Karl
