Bresser National Geographic 76/350 Dobson telescope
Looking for a reliable and affordable telescope that will introduce you to the fascinating world of the night sky - without unnecessary complications? The Bresser National Geographic 76/350 Dobson reflector telescope is exactly what you need. Its compact size, simple operation and solid optics make it an ideal companion for anyone just starting their astronomy journey - as well as for more experienced observers looking for a portable instrument to take on trips.
Optical design and construction
The telescope uses the proven Newtonian reflector design with a primary mirror diameter of 76 mm and a focal length of 350 mm. The resulting focal ratio of f/4.6 makes it a relatively fast instrument, particularly well suited for observing the Moon, bright planets and open star clusters. The Dobsonian alt-azimuth mount allows intuitive object tracking by moving in two axes - up/down and left/right - with no alignment or polar alignment required. For visual astronomical observation, it is a solution that simply works.
Magnification range
The achievable magnification ranges from 18x to 116x depending on the eyepiece and Barlow lens used:
- Low magnification (18x with 20 mm eyepiece) - provides a wide overview field, great for orientation and viewing extended objects
- High magnification (116x with 6 mm eyepiece and 2x Barlow lens) - reveals details on the lunar surface or the disc of Saturn with its rings
Ready to use straight out of the box
Bresser designed this telescope to be ready for use immediately after unboxing, with no need to purchase additional basic accessories. The package includes everything you need for your first observing nights.

Important note - for night sky observation only
Newtonian reflectors and their optical design are optimised exclusively for astronomical observation of the night sky. The image in the eyepiece is inverted and mirror-reversed, which makes no difference when viewing stars and planets, but this type of telescope is not suited for daytime observation of landscapes, birds or distant terrestrial objects. If you are looking for a versatile instrument that can also be used during the day, consider a refractor (lens-based telescope) with a straight or zenith finder scope for terrestrial use.
What can you observe?
The Bresser National Geographic 76/350 Dobson is an excellent choice for anyone who wants to observe:
- The Moon with its craters and surface detail
- Planets of the solar system
- Bright nebulae
- Open star clusters
All this without any compromise on ease of use and portability.
