Tele Vue Refractors |

No single telescope is best for every application. For example, to see the faintest galaxies and nebulae or deeply resolving globular clusters, a big aperture telescope (such as a 12" or larger) can't be beat. However, fine, small APO refractors offer levels of portability, versatility, field of view, day/night viewing, CCD imaging, digiscoping etc. that large instruments can't manage. And because APO refractors produce images essentially free of color fringing, and have no central obscuration, both low and high power views have the highest contrast. They are also rugged and easily carried on-board airplanes, so you can travel to exotic and dark-sky locations. Ironically, many large instruments have insufficient field-of-view to observe some spectacular deep-sky objects such as the North American nebula, all three sections of the Veil Nebula, the full extent of the Andromeda Galaxy, the Double Cluster, etc. |
