For a really great stargazing experience then this 2.7 observatory dome could be worth a try. It has a height of 1.7m with a diameter of 2.7m and a wall height of .25m. The idea is that it can be used for stargazing as there is a hatch in it that opens that you can observe the sky through. It is self-assembly but it is possible to get someone to install it for you should you want to. It will offer a great opportunity to watch the skies from inside your home in a similar way to a proper observatory.
