An old and respected optical company that has established itself mainly in governmental and scientific areas. They have, however, lent their name to several selections of amateur telescopes over the last few decades. A few of these have been refractors.
| Model 454 was a 60mm f/15 optical tube on a equatorial mount with a .965"" focuser and 5x24 finder. | ||
| Banner 1000 was a nice 80mm f/12 unit on a good equatorial mount with Polar axis finder, 1 ¼" accessories and 6x30 finder. A quartz single axis drive corrector was available as an option. | ||

| Bushnell Discoverer | ||
| Discoverer is primarily a spotting scope with a 60mm objective and 15-60x zoom eyepiece. The zoom is internal to the telescope tube, hence when used with the accessory telephoto lens adapter really provides the user with a zoom lens. The tube contains a tripod adapter block for standard photo tripod. | ||
| Spacemaster - This is also a 60mm spotting scope, but with an integrated poro prism. As such it ahs only a single focal length, but correspondingly sharper images. It allows interchangeable eyepieces and can be used with an adapter as a telephoto lens. The tube contains a standard tripod adapter block. The Spacemaster II was the same basic telescope, but with a 70mm semi- apochromatic objective. | ||
