Product description

Astrograph with fast focal ratio: A flagship model with outstanding performance and ease of use for visual observation and astrophotography.

The optical design, consisting of two SD lenses and one ED lens delivers images free of aberrations practically. It achieves sharp and wonderfully beautiful star images that are even in image quality throughout the edges when you take the images with a full-frame digital SLR camera or a larger 44mm x 33mm format camera. You will enjoy incredibly high performance, from observing planets at high magnification to capturing deep-sky objects in a relatively wide field of view.

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.
