Thesmallrefractingtelescopewithitssimpledirectdesignandconstructionand permanently aligned optics is the time tested standard for personal use. Easily portable, it can be taken out of the house and set up at a moment's notice. Or, it can be packed conveniently into a small car for traveling to a dark observing site.
