TS Newtonian 76/700 on a simple alt-azimuth mount

If you are looking for your first telescope you should consider this one. In many cases beginners do not yet know whether they will stick to amateur astronomy, or whether this hobby is not for them at all. Spending several hundred Euro for something you do not know whether you will use it at all is not a good idea, obviously. This is where this telescope comes in.

Observing with the 76/700 Newtonian Reflector:
This telescope will offer beautiful views of many objects, both within and beyond our solar system. The precisely figured primary mirror will show you many open clusters as they really are: Hundreds of pinpoint stars huddled close together in the blackness of surrounding space. 76mm of aperture are enough to see bright galaxies and gas nebulae like the Great Orion Nebula or the ring nebula in Lyra. As long as you do not expect such colourful images as those you can see on the internet (taken with the three billion Euro Hubble Space Telescope or other professional equipment) you will enjoy countless hours of awe under the night sky.

Within our solar system you will also find plenty of fascinating objects. You will discover the phases of Venus, the cratery surface of the moon, the bands in Jupiter's atmosphere and, of course, Saturn's famous rings.

The Alt-Azimuth Mount:
A simple but efficient design that allows you to easily point the telescope wherever you like. The aluminium tripod is adjustable in height. We recommend this telescope to children because of its ease of use. Only the refractor 70/800 is easier to use than this telescope.

Recommended Magnifications: 28x to 120x

The 1,25" Focuser:
One of the major drawbacks of most telescopes in this price range is that they are equipped with a 24.5mm focuser only. Most good quality accessories are only available for 1.25" focusers, which means that you would not be able to upgrade your telescope by purchasing better accessories.

Our 76/700 Newtonian features a proper 1.25" focuser. That way you can use good filters and eyepieces. You may even try taking a few snapshots of the moon and planets.

Complete Set of Accessories:
The Newtonian comes complete with a set of accessories to get started:

- 5x24 finderscope
- 1.25" Huygens eyepieces: 20mm (35x), 12.5mm (56x), 4mm (175x - usually not recommended)
- 2x barlow lens (not suitable for use with 4mm eyepiece)
- erecting lens for terrestrial use

----------------------------------------------------------------------------------------------------------------------------------------------------------------

If there ever was a "classical" entry-level telescope, this is it. It combines a respectable aperture of 114mm with a properly dimensioned equatorial mount. All kinds of amateur astronomy - be it observing the planets, deep sky objects or even astro-imaging - are possible with this allround telescope.

There are many different brands of this classical telescope, and sometimes they vary widely when it comes to accessories, optical or mechanical quality. Some of these telescopes feature the old 24.5mm focusers that essentially cut you off from all higher quality accessories.

Our TS Newtonians all have a standard 1.25" focuser that enables you to use nearly any accessories you like.

Observing with the 114/900
114mm aperture means a lot of light for your eyes. Many objects beyond our solar system are within the reach of this telescope. You will see why M-57 is called the "ring nebula"; M-13 is dissolved into single stars near the edge. In the constellation of Virgo you will be able to see various small galaxies.

The relatively small secondary mirror means a very good contrast and sharpness on the moon and the planets. You will see the atmospheric bands on Jupiter and Saturn's famous rings. The relatively large aperture allows for the use of colour filters - you will still have enough light for your eyes.

Astro Imaging
The 1.25" focuser not only enables you to use standard accessories for visual use, but also for astro imaging. With our projection adaptors you will be able to take impressive images of the moon and the planets.

The easiest entry into astronomical photography is to put a digital camera behind the eyepiece of your telescope. We offer adaptors for most digital cameras.

Specs:
Precisely figured primary mirror - diameter (aperture) 114mm, focal length 900mm, focal ratio f/7.9.
Diameter of the secondary mirror is 22mm.

Recommended Magnifications: 23x to 170x

1.25" Focuser:
Even though everyone agrees that a 1.25§ focuser is a necessity many cheap telescopes still have the old 0.96" models. Our TS Newtonian of course has a true 1.25" focuser, allowing for the use of all high-class accessories.3

6x30 Finderscope:
Not just cheap plastic, but a decent quality finder. You will notice the difference when you try to find an object.

Sturdy Equatorial Mount:
The mount holds our TS 114/900 Newtonian almost without vibrations. It is well suited for visual use and your first steps in the grand field of astro-imaging. One single screw needs to be removed in order to detach the mount from the adjustable height tripod.

The mount comes complete with slow motion cables in both axes. A tracking motor is available as an optional extra, allowing for more comfortable observations and astro-imaging.

Complete Set of Accessories:
- Kellner 25mm (36x)
- Kellner 10mm (91x)
- 2x Barlow Lens (doubles the magnification)
- Moon filter
