I'm doing a project that involves telescopes. I need to know if I took a third 
lens out of a refractor telescope and then put into a smaller refractor 
telescope with no third lens would it make the image right-side-up or just 
make it bigger. If you can, I want to know if this would be a good scince 
project. Please respond before the end of the week.
Thank you.
