1.25" Filters

The Astronomik H-alpha filter is a narrow band filter for CCD photography. The filter lets the H-alpha light of emission nebulae pass and blocks nearly the whole remainder of the spectrum where the CCD is sensitive.

The Astronomik 6nm H-alpha filter is an extremely narrow emission-line filter for CCD photography.

The Astronomik H-beta is a filter for visual observation, in particular with instruments of larger aperture.

The Astronomik 1.25" IR Blocking Filter is an infrared-blocking filter for digital photography.

The Astronomik 1.25" IR Blocking Filter is an infrared-blocking filter for digital photography.

These filters provide a natural color reproduction of planets, stars, emission- and reflection nebulas.

The Astronomik UV and IR cut Filter is great for for digital photography!

This Multicoated (MC) glass serves as dust protector or to keep your system parfocal with other Astronomik filters.

The Astronomik OIII CCD filter is a narrow band emission-line-filter for CCD photography.

From the start, the Astronomik OIII filter has been very specifically designed for the visual observation of gaseous and planetary nebulae.

The Astronomik ProPlanet 742 is the ideal filters for the reception of the moon and planets, notably Mars, with telescopes from 6" (150mm) aperture.

The Astronomik ProPlanet 807 filter is a deal addition to the Astronomik  ProPlanet 742 for imaging the moon and planets, with telescopes larger  then 10" (250mm) when the seeing is poor.

The Astronomik SII-CCD filter is a narrow-band-filter for CCD photography.

The Astronomik UHC filter is for visual deep-sky observation.

The Astronomik UHC-E filter is THE budget filter for deep-sky observation of emission nebulae and comets under light polluted skies.

This is our newest high quality filter that eliminates most color aberration inherent in achromatic refractor telescopes. The filter also reduces your view of the blue hue around lunar and planetary subjects. Features multi-layer coatings for 95% transmission.

Kit includes: #8, #47, #82A, ND-13 filtersCelestron color filters are mounted in black anodized aluminum cells with the Kodak Wratten Series Number individually engraved, and come available in 4 assorted kits packed in plastic cases.

Light Pollution Reduction (LPR) Filters are designed to selectively reduce the transmission of certain wavelengths of light, specifically those produced by artificial light. This includes mercury, and both high and low pressure sodium vapor lights. In addition, they block unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e. sky glow). As a result, Celestron LPR Filters darken the background sky, making deep-sky observation and photography of nebulae, star clusters and galaxies possible from urban areas. LPR Filters are not used for lunar, planetary or terrestrial photography.

Celestron's Moon Filter is an economical eyepiece filter for reducing the brightness of the moon and improving contrast, so greater detail can be observed on the lunar surface. The clear aperture is 21mm and the transmission is about 18%.
