naked-eye
Requiring no telescope
Naked-eye describes what can be seen without optical instruments—no telescope, microscope, or binoculars: The comet is visible to the naked eye.
The phrase usually modifies observation of distant or small things: naked-eye astronomy, barely visible to the naked eye.
The "naked" suggests unassisted, unenhanced vision.
