The advantages in a nutshell:

  • Enhances planetary nebulae and supernova remnants
  • 12nm bandpass – darkens the sky and enhances the nebula
  • Suitable for telescopes from 200mm aperture upwards
  • Comes with its own test certificate
  • Dreamlike contrast – see significantly more nebula

This is made possible by the technology employed with this interference filter. It allows through the narrow range of wavelengths from doubly ionized oxygen. Whether under a light polluted or a pristine dark sky – this filter allows you to see objects more clearly because it enhances the contrast between the object and background of the night sky. This filter has a 12nm bandpass, so it only allows a very narrow range of light frequencies to pass through. It and also keeps unwanted stray light away.
When you first see the Veil nebula in Cygnus using the filter you will be thrilled. Without a filter, any detail can only be observed with very large instruments. But the OIII filter lets its unexpected extent be seen even in small telescopes. You will see the universe with completely new eyes.
You can also observe:
Dumbbell nebula, M27
Omega nebula, M17
Owl nebula, M97
Eagle nebula, M16
and many more
For which telescopes?

The Omegon pro OIII filter is ideal for medium and large telescopes – perfect for apertures of 200mm and upwards. It can also be used with small telescopes when used at low magnification.
