Ideal addition to the Astronomik ProPlanet IR 742 for imaging the moon and planets, with telescopes larger then 10" (250mm) when the seeing is poor. This filter is an ideal complement to the ProPlanet IR 742 for use with converted DSLR cameras, CCD cameras and Webcams.

Purchase additional filter holders to easily use multiple filters with the Starizona Filter Slider.

The narrowband UHC filter, like the O-III filter, isolates the two doubly ionized oxygen lines (496 and 501nm) in addition to the hydrogen-beta line (486nm) emitted by planetary and most emission nebulae.

The Optolong Moon & Skyglow filter is designed to darken the background sky by blocking light transmission from skyglow 589nm and many street light emissions from artificial light.

This ZWO 2″ IR/UV CUT-OFF filter is suitable for color cameras with AR protect window.

Infrared-blocking filter for digital photography.
The filter should be used as a standard at all imaging applications with sensors having a low sensitivity in the UV, e.g. Webcam, DSI and LPI from Meade or most video systems.

Ideal filters for the reception of the moon and planets, notably Mars, with telescopes from 6" (150mm) aperture. The ProPlanet IR 742 only allows infrared light with wavelengths of more than 742 nm to pass.

Fine planetary detail is almost always enhanced with the use of color filters. Since different planets exhibit different colors on their surfaces, it only makes sense that if a filter restricts a neutral color and transmits a feature color

Standing for "City Light Suppression", the Explore Scientific 1.25" CLS Nebula Filter is not just for observing nebulous objects, as it lets a broader swathe of wavelengths through to the observer than either the OIII or UHC Explore Scientific filters do.

More versatile than the OIII filter, the Explore Scientific 1.25" UHC Nebula Filter will work on a broader range of nebulous objects, due to its dual peaks in transmissions on both broader OIII lines and Hydrogen wavelengths

This new generation of Baader CMOS-filters for LRGB astroimaging features increased contrast, matched for typical CMOS quantum efficiency and s/n ratio

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

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.
