Overview

The Bresser Messier Dobson 5″ is a compact tabletop reflector telescope featuring powerful Newtonian optics. It has earned wide popularity thanks to its combination of effortless operation and genuinely high-quality image performance. The telescope arrives factory-assembled, so you can start observing immediately after unboxing - simply place it on a table, point it at your chosen target, and begin exploring the sky. No complex assembly or technical expertise is required. The Dobsonian mount allows the optical tube to move smoothly on two axes, making it easy to track objects across the sky. This telescope is an excellent choice both for complete beginners and for more experienced observers looking for a reliable and portable instrument.

Optics and Performance

The 130mm aperture and 650mm focal length deliver a large light-gathering surface area, enabling observation of a wide range of astronomical objects. The primary mirror has a parabolic shape and is made from high-quality optical glass, ensuring sharp, high-contrast, and richly saturated images free from unnecessary distortion. The 55mm secondary mirror provides uniform illumination across the entire field of view. The telescope offers a magnification range from 26x up to 260x, making it equally suitable for wide-field views of large objects and for detailed study of planets and the Moon. These characteristics also make the instrument capable of basic astrophotography.

What Can You Observe?

Craters and mountain ranges on the Moon
Planetary discs and the rings of Saturn
Nebulae and star clusters
Distant galaxies
Faint deep-sky objects invisible to the naked eye

The Bresser Messier Newton Dobson reflector delivers an outstanding performance-to-price ratio for this class of astronomical telescope.

Typical magnifications

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

Maximum useful (2D):
260x
(with a 2.5 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):
181x
(with a 3.6 mm eyepiece)

TIP: Binorum Plössl 3,6mm 43° 1.25″ Ultra High Power Planetary Eyepiece

39.35 €

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):
130x
(with a 5 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):
93x
(with a 7 mm eyepiece)

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):
65x
(with a 10 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):
43x
(with a 15 mm eyepiece)

TIP: Binorum Advanced 15mm 66° FMC 1.25″ Eyepiece

57.10 €

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):
22x
(with a 30 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.
