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

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.

The Explore Scientific H-beta filter uses a characteristic property of the so called emission nebulae. Those objects glow in special colors, the so called emission lines. Those emission lines are linked to chemical elements - in this case hydrogen.

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.

Standing for "City Light Suppression", the Explore Scientific 2" 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.

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

The EXPLORE SCIENTIFIC H-Alpha filter uses the characteristic of the so-called emission nebulae. These objects glow in certain colors, the so-called emission lines.

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.

The EXPLORE SCIENTIFIC S-II nebula filter blocks all other colors (and thus almost all artificial light) and lets only the emission lines of ionized sulfur at 672 nm through.

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

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
