  • Celestron designed this series with the finer points in mind so you, the user, can benefit from the features that make this series unique. The Omni is a 4 -element premium symmetrical Plossl optical design.

  • A polariser or polarizer enhances contrast during planetary observation. Useful for solar work in conjunction with Baader Herschel Wedge Prism. Planoptically polished.

    Please ensure you order the size you require - Available in 1.25 inch (31.7mm) or 2 inch (50.8mm)

  • With the help of this special CE certified film with a filter factor of 100,000 you can observe the sun directly with your binoculars or telescope

  • Baader IR-Pass filter blocks wavelengths below 670 nm. At these longer wavelengths, planetary images are less disturbed by atmospheric conditions. By combining a luminance image taken with the IR-Pass filter, along with RGB frames, overall image sharpness is significantly enhanced. There are some amazing images taken of the planets using this technique.

    • Transmission peak approx. 80% at 350nm, bandwidth 60nm (320-380nm), completely blocking the entire spectral range from 200nm to 1120nm.
    • Dielectric multi-coating on optically polished Schott Glass
    • Enables imaging in the deep UV spectral region. A "breakthrough" for imaging the planet Venus! Allows amateur astronomers to capture cloud structures of the Venusian atmosphere
  • Baader Planetarium Solar Continuum Filter - 1.25"

    • This Baader Planetarium Solar Continuum Filter comes in a fully-threaded 1.25" round cell.

    Please ensure you order the size you require - Available in 1.25 inch (31.7mm) or 2 inch (50.8mm)
