P.s russ.
I can just about make out your imaging setup in your profile pic. Very impressive! Is that a 12" or a 14"? I have a modest but more widefield setup with an orion ex80 and an old canon dslr. But does the job. Not so many clear nights though in Scotland to play though.
Damit russ! Haha can't believe they've beaten me to the punch! Oh well.
Thanks for the explanation. I understand knw what you meant by only using the biggest ring. Makes sense.
I'm really terrible at maths so any chance you could explain the formula for me? Am I correct in thinking pi r 2...
@Russ. I was thinking you would need to swtich tubes for sake of the gravity to speed would max out before you would reach escape velocity. So you move to the bigger one to reduce the gravity and then accelerate again to max and so on.
@vanadiam. Thanks for your reply. Yes i dee the problem...
Hello all! I have longed envisaged a new type of space launching device, one that would be reusable and cheap to operate.My idea is to have a large set of concentric circular tubes laid horizontally in some desert or something. The spaceship would use magnetic levitation to float in the tubes...
