Dobsonian telescope with over 30 centimetre mirror from Bresser

April 3 2024, Stefan Taube

Dobsonian telescopes are simple in design and intuitive to use. They are therefore particularly popular with newcomers to astronomy and occasional observers. But experienced amateur astronomers also love this type of telescope, as the simple design allows the use of a large mirror at a fair price.

The traditional Bresser company now offers a Dobsonian telescope with a 305 millimetre mirror diameter in its Messier series: N 305/1525 Messier Hexafoc

This model also shares the special advantages of the Dobsonian telescopes in the Messier series:

  • Newtonian optics with parabolic primary mirror
  • Large altitude wheels and azimuthal needle bearing for movements without jerking
  • Tube with tube clamps: The telescope can be finely balanced. It is even possible to use the optics on a different mount.
  • The supporting box can be assembled in just a few minutes using metal furniture connectors.
  • A suitable filter for observing the sun is already included in the scope of delivery.

The tube of the largest model N 305/1525 Messier Hexafoc is made of fiberglass and is therefore relatively easy to transport.

You can find more information and the current price for this 12-inch telescope here in the shop.

Telescopes from Bresser’s Messier range

September 19 2022, Stefan Taube

The manufacturer Bresser offers a rich variety of telescopes for hobby astronomers in their Messier range. Options range from economically-priced entry-level models through to telescopes which make all of your wishes come true.

Large selection of scopes and mounts:

Within the Messier range, you can find optical telescopes, Newtonian telescopes and compact Maksutov scopes. The latter are very good for travelling and are designed for planetary and lunar observations.

These telescopes are equipped with a rail to attach them to astronomical mounts. As these rails conform to the Vixen style, the telescopes can be used with almost every mount.
For the Messier range, Bresser has developed both the EXOS-1 and the EXOS-2 mounts. They are adapted for these scopes. The mounts can be purchased with or without a motor. If you want a reasonably-priced entry-level model, you can leave the motor out. You can always add one later. Motors are especially necessary for astrophotography. You can find upgrade sets here in our shop.

The EXOS-2 mount is also available with computerised controls (GoTo).

Ideal for beginners: Dobsonian telescopes

Within the Messier range, Bresser also offers a range of Dobsonian telescopes. The larger models feature altitude bearings which provide high levels of stability in all positions. Thanks to the OTA brackets, the tubes on these Dobsonian telescopes can also be placed on other mounts.

Dobsonian telescopes are ideal for optical use and are very reasonably priced.

All telescopes come with a suitable solar filter which is placed on the front end of the telescope. This makes it possible to safely observe the Sun.

Dobsonian telescopes with special Bresser enhancements

Messier-series telescope with add-on sun filter

Bresser’s Messier-series Dobsonian telescopes  stand out from the crowd due to their features, which cannot be found on other brands of comparable telescopes:

  • The telescope tube is held in place using tube clamps. This means the tube can be rotated along its axis to find the perfect eyepiece position. It can be optimally balanced by adjusting the tube within the tube clamps. You can also fully demount the tube and use it with an equatorial mount, for example.
  • The altitude bearings have a comparatively large radius. This facilitates finer adjustments along the vertical axis. Many Dobsonian telescopes in this price range do not have proper altitude bearings!

    The altitude bearings with tube clamps glide along the rockerbox.

  • The so-called rockerbox, upon which the telescope is placed and which enables rotation in azimuth, is fitted with quick-release fasteners on the Messier Dobsonians, the kind you are familiar with from furniture. This enables the box to be quickly and simply assembled. In this way, the box can be disassembled again and again.
  • The Hexafoc focuser is superior to focusers on comparable telescopes by other manufacturers.

The large Hexafoc focuser does not cast a shadow on wide-angle eyepieces.

  • A compatible solar filter is supplied with the product. As the tube is closed, no sunlight can enter the telescope from the side. This makes it possible to safely view the Sun.

In addition to these features, you also receive a Messier Dobsonian with high-quality optics and a parabolic mirror which is fully adjustable. This makes it possible to start a lasting relationship with the night sky. The Messier Dobsonians are available in two sizes. You can find both models here in our shop.

The optics are fully adjustable.

Note: These telescopes are named after Charles Messier (1730-1817), whose “Catalogue of Nebular Objects” contains a number of celestial objects which you can observe using these telescopes. A modern guide to Charles Messier’s objects can be found in Cambridge University Press’ book The Messier Objects.
