The table top tripod is only useful if you happen to have a table with you when you want to use it - thast makes getting out to a dark sky site - of which there are many in NZ, I do not know where you live, but I know from personal experience that you do not need to travel far for a truly dark sky - bit more from Aukland and Wellington, but still not as far as most nations. However, I appreciate that as a 13 years old, you are not yet driving so it is not as simple as hoping in your car.
