Black anodized aluminum filter cell with M28.5 x 0.6 threads and Schott B270 glass

Celestron

Celestron Nebula Filter for Origin Telescope

SKU CH-0KZD-ND33K

A nebula filter that blocks light pollution and transmits Ha, Hb and OIII wavelengths for the Origin telescope, using Schott B270 glass in an M28.5 x 0.6 threaded cell

  • Enhanced nebula contrast via dichroic multi-bandpass coatings blocking light pollution
  • Superior optical clarity with Schott B270 glass for minimal distortion
  • Precision fit using M28.5 x 0.6 threads for standard 1.25" telescopes
  • Durable black anodized aluminum cell protects glass during field use
  • Optimized transmission of Ha, HB and OIII wavelengths for emission nebulae

Purpose-built Nebula Filter

The Celestron Nebula Filter is engineered for the Origin Intelligent Home Observatory Telescope to improve deep-sky imaging. It targets emission nebulae by transmitting Hydrogen-alpha, Hydrogen-beta and doubly ionized oxygen wavelengths while blocking light-pollution sources. Astronomers and astrophotographers gain clearer views of objects such as the Orion Nebula M42 and the North America Nebula NGC 7000.

M28.5 x 0.6 Thread Compatibility

The filter uses M28.5 x 0.6 threads that match standard 1.25 inch telescope filter threads for a secure fit. Schott B270 glass with dichroic multi-bandpass coatings provides high transmission at the key nebular lines and minimal distortion. The black anodized aluminium cell protects the optical surface during repeated handling in the field.

Sustained Imaging Contrast

During long exposure sessions the filter maintains consistent contrast by continuously rejecting unwanted wavelengths from skyglow. Light-polluted sites benefit most as the coatings preserve nebular detail without shifting transmission over time. The robust housing keeps alignment stable so image quality remains repeatable across multiple nights.

Questions about this item

How does the multi-bandpass coating change what the Origin telescope actually records?

The dichroic multi-bandpass coatings transmit Hydrogen-alpha, Hydrogen-beta and OIII wavelengths while blocking other light, so emission nebulae appear with higher contrast against light-polluted skies.

What does the M28.5 x 0.6 thread specification limit in practice?

The M28.5 x 0.6 threads match standard 1.25" filter threads, so the filter screws directly into the Origin's optical train without adapters.

Will the Schott B270 glass cell clear the Origin's focuser drawtube?

The black anodized aluminum cell is built to the 1.25" thread standard, so it fits within the Origin's standard filter recess without vignetting.
