To Fit Celestron 127 SLT / Skymax 127

This filter also fits:

All Optical Tube O.D.'s of 137-143mm

The UHC (Ultra High Contrast) broadband filter is designed to improve the visibility of various deepsky objects by selectively reducing the transmission of wavelengths of light pollutants

The Astronomik UV-IR Blocker lets the full range of sensitivity of the human eye (according to DIN 5031) pass, and blocks all other parts of the spectrum in the UV and IR. The Astronomik UV-IR Blocker is the ideal choice as a luminance filter for any kind of digital photography.

Astronomik now offers you a range of three different UV+IR blockers as Luminance filters. The different spectral window of each new Luminance filters is designed to tune your setup to get the sharpest image from any optical design and any camera.

Enhances contrast during planetary observation.
Also extremely Useful for solar work in conjunction with Baader Herschel Wedge Prism (#2956500V or #2956500P)

This very useful addition to the Baader filter range is intended for the luminance channel in astro imaging. Using narrowband filters can often result in slightly dimmer images, which can be difficult to resolve to a focus.

The CLS-CCD broadband filter is designed to improve the visibility of various deepsky objects. By selectively reducing the transmission of wavelengths of light pollutants, specifically those produced by artificial lightings

The Astronomik UHC-E filter is our budget filter for deep-sky observation of emission nebulae and comets under light polluted skies. It’s particularly suitable for small ’scopes.

The Optolong CLS (City Light Suppression) broadband filter is designed to improve the visibility of various deepsky objects by selectively reducing the transmission of wavelengths of light pollutants

UV-IR cut filter is designed for ultraviolet and infrared wavelength
blocking to improve sharpness of the image as most of the optics are
designed for the visible spectrum

The Baader C2 SWAN-Band-Filter with ≤ 15 nm Half-Band-Width isolates the two C2 lines at 511 and 514nm – leading to a contrast gain for comet hunters!

The Astronomik CLS is a budget filter for visual observation, Black & White photography and CCD photographs of nebulae, galaxies and star clusters with astronomical instruments of any size.

Baader double Polarising-Filter with rotating cell mount. For perfect light management when viewing bright objects.

Observing difficult, dim Deep Sky targets like Planetary Nebulae and certain supernovae remnants, such as the Veil Nebula in Cygnus from light poluted environments can be a very tricky business. This is where the Explore Scientific 1.25" O-III Nebula Filter shows its strengths.

We are glad to announce the availability of 2 inch mounted deep space photographic filters for broadband and narrowband usage.
