How to use LDR module to generate images?

I am trying to make a reflector-type telescope from a concave mirror having a focal length of 100mm or 10cm. Now the problem is, I don't really have a secondary mirror that small to see direct images from an eyepiece (well, that eyepiece is made of cardboard, and lenses are scavenged from binoculars). So I was thinking if it is possible to add an LDR sensor and use it to generate images?

Only if your "image" is a single point. Think about what your "image" will need to be formed. It needs X and Y movement. Can you get your LDR to move that way?
