Yes, you can keep your glasses on when viewing through a telescope if you like, and in fact you will definitely need to leave them on if you have astigmatism. Consumer-grade telescopes can have imaging defects such as color fringing a kind of chromatic aberration that happens when the lens is unable to bring all wavelengths of color to the same focal plane. There are several characteristics you will want to pay attention to when buying a telescope, including Aperture: An old adage about choosing the best telescope goes like this: "Buy the biggest telescope you can afford that you can set up by yourself and will use" While there is obviously a bit more to it than that, this is wise advice because it is a fact that the bigger the diameter of the primary optics, the more you will see. The best telescope is one that you can afford, that you can set up on your own, and that you will use! Another thing to think about is your seeing and also your pointing / guiding accuracy.

APO refractors, however, can be nearly free of extra color. Please use another browser such as Chrome, Edge, Firefox, or Safari for the best experience. The lack of refractive lens elements allows this telescope design to detect wavelengths broader the visual spectrum making them very useful for measurements in the ultraviolet (UV), near-infrared (NIR), and infrared (IR) wavelengths. Nexdomes higher walls make entry easier andprovide more room for longer telescope tubescompared to conventional domes.
