Typical magnifications

The recommended magnification is highlighted in yellow.
D = telescope aperture in millimeters

Maximum useful (2D):
406x
(with a 6 mm eyepiece)

Maximum Useful Magnification (2D)
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 (1.4D):
271x
(with a 9 mm eyepiece)

TIP: Binorum Advanced 9mm 66° FMC 1.25″ Eyepiece

56.45 €

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 (1D):
203x
(with a 12 mm eyepiece)

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

Optimal (0.7D):
143x
(with a 17 mm eyepiece)

TIP: Binorum Super Plössl 17mm 50° SPL 1.25″ Eyepiece

46.20 €

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 (D/2):
102x
(with a 24 mm eyepiece)

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 (D/3):
68x
(with a 36 mm eyepiece)

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 (D/6):
34x
(with a 72 mm eyepiece)

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.
