Camera Obscura Scope

A simple tube camera obscura based on the construction found here:

I recommend printing the longer eyepiece if your printer has the volume for it, it is easier to focus your eye on the image.

Tweaking the camera's parameters such as pinhole diameter and the distance form the pinhole to the projection medium can affect the focus and brightness of the image. Feel free to remix if you find a combination that improves upon the current configuration:

pinhole diameter: 2mm
distance to projection medium: 50mm
