Those tiny web or surveillance videocams (With very tiny lens and sensor) are rather cheap and worthy way to check for digiscoping / digi-microscoposcoping. It has been used for astro work and I remember intel had a commercial version on a cheap microscope that was quite cheap in the package. And yes I would think you will not come with a sharp image like that of SLR but still if you really need this type of sharp image, your best bet is that old approach via T mount.
