it is very hard to position a telescope by hand to the eyepiece. When I tried it I saw more sunspots with naked eye than my phone camera could see. Do you think the sensors are good enough to capture all details you see?

Scott seems to be one of the more private moonwalkers in comparison to Buzz or Charlie Duke. He didn't show up to any recent space events and didn't publish memoirs

He did this talk on Apollo guidance computer in 1982

could you have bought a pro camera for that cost back then? since instant film isn't meant to be professional studio quality

would that price have made it into "pro camera" territory by any means?

it looks like Polaroid sells film for it online now, but it isn't commonly distributed at most stores

Reply to comment by _Ilya-_- in TIL honeybees can understand the concept of zero. by BogdanAnime

did it used to be infinity at some point or a middle school watered down version? because in school, a boy once asked me "Do you know what something divided by zero is?" I asked what? and he dramatically announced "The answer is infinity!"
