Product description

More about the series FluoroStar...

The Fluorostar’s objective lens consists of three lenses with an air gap, which use special FPL-53 ED glass by Ohara, Japan, combined with lanthanum glasses. This extremely high-quality triplet design guarantees colour purity and clarity which leaves nothing to be desired - a true high-end instrument!

Combine this apochromat with a suitable high-quality zenith mirror from William Optics and you can see the stars with a level of clarity which other telescopes rarely provide. Binary stars separate and appear sharp, Jupiter’s bright bands and zones reveal striking details and Saturn's rings appear as though they are flying past in a spaceship.

With its large aperture, without obstructions by the secondary mirrors required by reflectors, the wide world of Messier objects and ambitious deep sky objects is at your feet. Anyone who has ever looked through such a high-quality apochromat has been lost to the universe forever!

For astrophotography, the large image circle provides illumination, even for full-frame cameras. Combined with the Flat7A flattener by William Optics, it produces a fast aperture ratio of f/5.6. The flattener can be securely screwed on to the focuser.

The focuser has smooth, precise reduction, a temperature display and a large adjustment range. It effortlessly supports heavy astrophotography equipment which can also be rotated to find the best position on the sensor.

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.
