The size of the core/lens will effect the overall Field of view and number of pixels on the target as well; Others are factors like lens quality (f/1 is ideal etc) core quality, image processing, sensitivity etc

that pulsar unit is a 38mm lens (f1.2) with a .17 core - So to get the improvements you are after you may need to look at something with a longer lens to get the magnification you need for a more defined image

Let's now see if you are knowledgeable enough to explain the disadvantages of a small pixel size. Go on, impress me!
