Cronus eyepiece case - an inexpensive cased set with quality eyepieces

During or after buying a telescope, you often find yourself asking "What extra eyepieces do I need?" or "How can I see the polar caps on Mars better, so that everything isn't so tiny?" You need look no further - get the Omegon Cronus eyepiece case.

3 eyepieces for medium and high magnifications

Three Cronus Omegon eyepieces - 9mm, 6mm and 4mm in focal length - cover the range from middle to higher magnifications with your telescope. The focal lengths of the eyepieces are optimal for telescopes with focal lengths from 750mm to 1200mm.


Focal length 1200mm - 133X, 200X, 300X

Focal length 1000mm - 111X, 166X, 250X

Focal length 750mm - 83X, 125X, 187X

Cronus eyepieces

Cronus eyepieces will provide you with fascinating views of astronomical objects right from the start. Don't make yourself miserable with inferior eyepieces, but set yourself up with eyepieces that will really do the performance of your telescope justice. With 16mm of eye relief, a large eye lens and comfortable viewing with the 60° field of view, everything is ready for your journey of discovery through the universe.

Ready for any celestial object If you have just bought a telescope, then this case provides the ideal supplement for observing at higher magnifications. Most telescopes only come equipped with simple eyepieces for lower magnifications. This case permits visual observing for all purposes. Whether observing detail in moon craters, planetary nebulas or on the planets of the solar system - you now have a suitable eyepiece for each purpose.

The universal moon and contrast filter from Omegon

The 1.25" moon filter, consisting of flat steamed glass, is simply screwed into the eyepiece thread. It reduces the brightness of the moon andthusenhances thecontrastin the observation. This filter is mainly necessary during the major moon phases, since the subjective glare of the moon then is strongest and can quickly become unpleasant.

More than a normal moon filter
However, the filter doesn't only offer advantages during lunar observation, but it also allows forhigh contrast observations of planets.It amplifies the surface details that make observation particularly interesting. The filter is most strong in the red / blue range. Thus, objects such as the 'Great Red Spot' and the bands of cloud on Jupiter appear clearer.
A particularly disruptive factor during observation is theillumination of street lights. This is blocked in the conventional spectral range so that high-contrast observations are possible.

This premium moon filter is much higher quality than similar products: There are some cheap offers in this field where the image quality of the telescope suffers due to the filter. This premium moon filter, however, is characterised byvery good characteristics.

The advantages at a glance:

  • Solid metal frame (no plastic) with a clean cut thread for the filter thread of 1.25" eyepieces
  • Clean and homogeneous glass
  • Solid plastic container
  • Fits into the filter thread of almost all 1.25" eyepieces
  • Attenuation of moon light (highly recommended up to 150 mm diameter)
  • Neutral representation of the moon
  • High contrast for planets and moon

The case - everything prepared

Accessories can be kept in this elegantly designed aluminium accessory case. Although the case looks very compact, it provides enough room for your eyepieces, filters and other accessories. This Omegon case has also been selected to provide sufficient room for further accessories. Even large 2 “eyepieces will fit in it due to its roomy12cm deep interior. Exactly where you locate each accessory is left completely up to you: The integrated 1cm x 1cm cube 'pluck foam' material allows eyepieces to be located fairly precisely.

The advantages in a nutshell:

  • eyepiece case with 3 quality eyepieces
  • pleasant observing due to comfortable viewing and a 60° field of view
  • covers medium and high magnifications
  • excellent addition to the standard eyepiece/s that came with the telescope
  • sturdy foam-filled aluminium case for the eyepieces and other accessories
