Experiment / demonstration: Set up military surplus command tent as camera obscura / pinhole projector for observation of full soar eclipse.(adsbygoogle = window.adsbygoogle || []).push({});

Problem: lacking in personal knowledge of the formula needed to determine correct focal length to hole diameter

Solution: Request assistance from actual scientists instead of Brittanica and Wikipedia

Thank you in advance for the help, I'll no doubt have further related questions on this project as I start attempting to do the maths.
