The highest magnification that a telescope can realistically use. Above this value, the image becomes dim, blurry, and shows no additional detail due to optical and atmospheric limits.

Resolving Magnification (1.4D)
The magnification at which the telescope reaches its maximum resolving power. Fine details become visible, but increasing magnification further does not improve sharpness.

High Magnification (1D)
A strong magnification suitable for detailed observations of the Moon, planets, and close double stars under good atmospheric conditions.

Optimal Magnification (0.7D)
The best overall magnification for most observations. It provides a good balance between image brightness, contrast, and detail, and is often the most comfortable to use.

Medium Magnification (D/2)
A versatile magnification range suitable for many deep-sky objects, such as star clusters and galaxies, as well as general lunar observing.

Low Magnification (D/3)
A wide-field magnification used for scanning the sky, observing large nebulae, and locating objects before switching to higher power.

Minimum Magnification (D/6)
The lowest practical magnification of a telescope. It provides the widest possible field of view and is mainly used for star fields, Milky Way observations, and object finding.
