Hardin telescopes aren't intended for use by the casual telescope hobbyist. The telescopes themselves, in terms of size and price, are often beyond the means of the casual astronomer. The company generally manufactures Dobsinian Telescopes that are over six inches in diameter. Dobsonian Telescopes are actually large Newtonian Reflector telescopes that are placed on a simple swiveling mount. The telescope itself features two high-precision mirrors that direct light at the eyepiece. The size of the telescopes and quality of the mirrors make them impractical for use by hobbyists.
