Thus, a 60-mm refractor may be theoretically capable of 300 x magnification, but the image quality would be terrible. Of these telescopes, the 8-inch reflecting telescope offers the greatest possible magnification. Its theoretical limit is 400 x magnification. The 6-inch telescopes are capable of 300 x magnification. The 80-mm refracting telescopes are capable of around 160 x magnification.
Image quality is also related to aperture.
A telescope with a large lens or mirror has a great deal more light-gathering ability than a telescope with a small lens or mirror. Ease of use. In this category, the alt-azimuth mounts rank higher than equatorial mounts on the same telescope type. The alt-azimuth mounts provide a very intuitive interface. Much like aiming a cannon, the user moves the telescope up or down, and rotates the telescope left or right.
