Let's say we're considering one particular telescope. If we want to see a bigger piece of the sky, what should we do? a Point the telescope at a different part of the sky b Use an eyepiece with a longer focal length c Use an eyepiece with a shorter focal length d Each particular telescope can only show one size of "piece of the sky"
