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.
