My personal list of almost all the stuff i'd want to try. You might also want to check out comments to perhaps find some other examples.
So, some are solitary, some wierd, some hyperactive, some dangerous. There should be something for everyone.
I've been creating this list for almost a year, adding everytime when i've found something or got inspired.
To some of examples i've added videos or sites showcasing and explaining them.
Here's the list:
1.) Get a telescope to observe stars, cosmic activities etc. Check sites giving informations about some noteworthy sightings.
https://www.youtube.com/watch?v=fj-P031VlbU - example
https://www.skyandtelescope.com/observing/ - an interesting site giving information about sights, interactive charts to map your sky, podcasts, equipment etc.
2.) Now i've found a fantastic upgrade to it! It's called FPV, an RC FPV to be more exact.
I completely haven't thought it could be this great!
