text: A 5" telescope has 5" of aperture. \n\nThe quick answer is, a large telescope would take advantage of the Meade LPI Camera. The camera has an effective magnfication somewhere in the range of an eyepeice that's 6mm in focal length, which means it's high magnification. The larger the telescope is in aperture, the higher the "resolution" which means you will be able to obtain better images with high magnification eyepieces.\n\nThat being said, your decision should ultimatly be based on your price range and what type of objects you'd prefer to image and view. An 80mm apochromatic refractor is a nice little quality telescope which will give nice (albeit small) images of planets and using a camera on it such as the Meade LPI will give you nice images, even of things you can barely see, as long as you have the proper mount. 80mm is rather small though and a larger telescope will allow you to be more versitile in your viewing. A lot of people are content with 8" Schmidt Cassegrains as an all around scope.
