The optics of the AC 120/700 make it an ideal Rich Field Telescope - that means that it shows a large section of the night sky and allows extended objects to be the observed in their entirety - such as widely dispersed open clusters.
The large 120 millimetre objective lens collects a lot of light - enough to make even faint deep sky objects visible.
Globular clusters and distant galaxies can be observed. Unlike a reflector telescope, a lens telescope has no secondary mirror and spider vane in the light beam's path. This means that the telescope can fully exploit its 120 millimetres aperture without any obstruction and ensures a sharp image without any diffraction structures. The objective lens is corrected for the chromatic aberration that refractors would otherwise suffer from, hence the name - Achromat.
Refractor telescopes have the eyepiece at a lower level - so observing can be carried out without need of a step or ladder. This also makes them ideal for use on balconies, at public shows or for observing with children.
It not only matters which telescope you buy but also where you buy it. Our additional services:
- We are a leading telescope dealer and know the devices we sell. Our customer service team will gladly help you after your purchase if you have problems with assembly or operation.
- We provide a copy of the 80-page Telescope ABC beginners handbook with every telescope.
- We also provide an edition of the exciting astronomy magazine, “Sterne und Weltraum” with each telescope.
