Alpine Astronomical
Alpine Astronomical Baader H-beta 8.5nm CCD Narrowband Nebula Filter (50.8 Round, Unmounted)
Key Features
  • Deep-Sky Viewing and Astrophotography
  • NOT Safe for Solar Viewing or Imaging
  • For Fast f/10 - f/2.8 Optical Systems
  • 486nm Wavelength, 8.5nm Half Bandwidth
Centered on the 486nm wavelength and passing a narrow 8.5nm half bandwidth, the Alpine Astronomical Baader H-beta 8.5nm CCD Narrowband Nebula Filter isolates a band that is easy to see—making it ideally suited for both visual and astrophotography use on telescopes with apertures of 8" and larger, or if you're working with large exit pupils. Through this filter contrast will be greatly increased, revealing hidden details of bright nebulae, and allowing you to see nebulae that were previously unviewable.

Alpine Astronomical Baader Overview

Centered on the 486nm wavelength and passing a narrow 8.5nm half bandwidth, the Alpine Astronomical Baader H-beta 8.5nm CCD Narrowband Nebula Filter isolates a band that is easy to see—making it ideally suited for both visual and astrophotography use on telescopes with apertures of 8" and larger, or if you're working with large exit pupils. Through this filter contrast will be greatly increased, revealing hidden details of bright nebulae, and allowing you to see nebulae that were previously unviewable.

Individually planeoptically polished, dielectric anti-reflection coated, and IR blocked, this filter uniformly passes the maximum amount of bandwidth possible to virtually eliminate halos, reflections, and ghosting. It is offered here as a 50.8mm square unmounted option for custom applications and imaging rigs.

This filter is intended only for deep-sky viewing and astrophotography, and should never be used for direct solar viewing or solar photography as permanent injury to your eye and equipment can occur, up to and including blindness.
