I decided to 3D model a finderscope. This is a device attached on a optical telescope. Optical telescopes are the ones that space stations use. This device can be expensive and does not come with the telescope. It is used as an aiming device. That would mean it does not require a high magnifying lens. I think this tool would be in handy daily. Astronauts are looking through telescopes all the time and they want to be as accurate as possible. This device, finderscope, will be useful.
