Product description

More about the series Pro APO...

Better astrophotos that help you discover the sky in a new way.
What is it that drives astrophotographers time and again? It is the fascination of depicting the sky in its most beautiful colours and shapes. With this apochromat, you can do just that. The premium ED glass and a colour-pure image make for enjoyable observations with fine details that would not be possible with basic optics. Rediscover the sky.

The advantages at a glance:

  • 40 mm sixtuplet ED apochromat with six lenses achieves apochromatic correction for fantastically clear, flat and colour-pure images
  • Two lenses made of high-quality ED glass offer high sharpness despite a fast aperture ratio
  • Integrated corrector ensures a flat and illuminated field even for full-frame cameras.
  • Helical focuser: even larger and heavier cameras can be focused smoothly and with high precision

Six lenses for superior field correction

No more low-contrast images. The apochromat shows what is truly possible: colour-pure and high-contrast astrophotography. The reason for this is a sophisticated optical design with two premium ED glasses for a crystal-clear image. The lens elements have been coated on all surfaces with an effective multi-coating to prevent reflections. Look forward to images that will remain in your memory.
