Because of increasing light pollution at our site, we will entertain the possibility of its sale! Folks who want to look at the Moon, Saturn and Jupiter occasionally but who are not interested in photography would do perfectly well with a medium-sized refractor on a simple quality alt-azimuth mount, whereas those who want to do photography would require an equatorial mount with either computerization or dual axis motor drive. These refractors are a good choice for beginners whose main interest includes traditional visual astronomy and/or daytime terrestrial use. Up until that time, telescopes required a heavy equatorial mount that produced a financial or weight barrier for some otherwise enthusiastic budding astronomers. The bigger the optics, the bigger and heavier the telescope. This takes us back to the solid equatorial mount, which is required for long exposures of galaxies, nebulae and other deep sky objects.
