I'm completely new to photography (beyond using my phone). I have been wondering (and googling) if it's possible to take pictures of people jumping out of airplanes from the ground. A typical skydiving plane is 38', flying at 80mph at 13,000ft.
I did a little bit of math based on the info above and I think a 1800 mm is the right choice, but then finding the actual airplane will probably be a very big plain. Is there some kind of computerized system available that can track an object (like telescopes do?). Should I go with a larger field and then crop down? Or is this simply not possible?
I'm doing this purely for fun and am open to all solutions at this point.
I know I'm probably missing some obvious stuff. Thanks for your patience.
