Recently I entered a discussion with a girlsomeone that has a relatively bigpopular YouTube channel where, together withwhich says among other things, she says that the earth is flat. I said that earth isn't flat because you can see the ISS by yourself through the telescope. She then said that I didn't see by myself, I'vewas reminded that I'd only seen it on the internet, but not actually seen it directly myself. Then she saidI was told that if I buy a telescope and film by myself, she they will also buy one, do the experiment, and record itpost the footage on hertheir YouTube channel.
So, what's the cheapest telescope that I can buy and record with a cellphone? I've seen people using a Nikon P9000 but what matters is its lens, which is already expensive, and the camera is expensive too. Maybe it's possible to buy a cheap photography lens that has boboth good quality butand high zoom and plugcan be used with a cellphone?
