Astronomik UHC-E Filter - Canon EOS R XL Clip Format

Astronomik UHC-E filters make a great low-cost alternative for viewing deep sky emission nebulae and comets in severe light pollution. This filter is especially well-suited for smaller telescopes up to 5" (125 mm) in aperture. Blocks superfluous light such as that from street lamps, as well as skyglow, while enhancing emission nebulae and comet contrast.

With a 45 nm FWHM (full width at half maximum), the contrast between your target object and the night sky is not enhanced as intensely as with a UHC filter. On the other hand, a greater amount of starlight is allowed to pass through. This makes UHC-E filters better suited for smaller aperture telescopes.

Astronomik UHC-E Canon EOS R XL Clip Filter Highlights

  • Compatible with Canon EOS R and RP full frame mirrorless camera models, this EOS R XL clip formatted UHC-E filter from Astronomik works best with smaller 5" (125 mm) maximum aperture telescopes
  • This filter does not necessitate any camera housing modifications to enable use
  • Offers quick and easy tool-free insertion using nothing more than your fingers, and comes with a small hook to aid in removal
  • Boosts contrast between deep sky emission nebulae and the skyglow background under heavily light polluted conditions
  • Due to the UHC-E filter's high FWHM of 45 nm, comet observation is attainable when it passes through a spectral line of Carbon
  • Transmission range of 465 nm to 530 nm as well as 645 nm and above
  • Parfocal with every other filter Astronomik produces
  • 1 mm glass thickness
  • Multi-layer coatings fully protect this filter from the negative impacts of scratching, aging, and high humidity
  • Diffraction limited, this filter will not diminish your telescope's optical performance
  • Each Astronomik filter comes with a durable plastic storage case of superior quality

Astronomik EOS R/RP Clip Filter System

Designed for mirrorless full frame Canon EOS R and RP cameras for use in both metropolitan and suburban viewing areas, Astronomik EOS R XL clip filters do not require any camera modifications in order to be used.

Installation may be performed without tools using only ones finger while a small hook is included for initial help with filter removal. As soon as the filter is out far enough to grasp, you can use your fingers to take it out and place it back in its case. Imaging can begin once this filter is rested flush into place and the camera lens has been reinstalled.
