From the start, the Astronomik OIII filter has been very specifically designed for the visual observation of gaseous and planetary nebulae. The extremely narrow pass band of the two OIII lines brings a substantial contrast gain
The ZWO 2-inch Filter Drawer with 20mm ring thickness design has been independently developed by ZWO, specifically for their FULL FRAME cooled cameras, the ZWO ASI6200MM-PRO and ASI6200MC-PRO.
The Astronomik UHC is THE filter for visual observing. You will enjoy using your Astronomik UHC filter because you will see more stars and more details in deep-sky-objects compared to using filters from all other manufacturers.
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
Single Astronomik Type 2C Green Filter in 36mm fitting. A superb addition to a monochrome system. Astronomik only deliver the highest quality in regards to coatings and quality.
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.
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.
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.
The Askar ColorMagic Duo-Band filter is a dual or triple bandpass narrowband filter designed for light polluted skies for COLOUR CAMERAS to maximise the output from your imaging time.
The L-Pro (L-Professional) 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 Solar Continuum Filter is practically a narrow band photosphere filter for solar observation in white light. It provides the highest contrast in the photosphere of the sun.
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 ProPlanet 642 BP is the lastest addition to the family of Astromik ProPlanet IR-pass filters. The filter thrills because of itīs wide range of applications.
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.
The Optolong extra Narrowband OIII-CCD 6.5nm filter is designed for nebula observation allowing 6.5nm bandwidth of light centered on a wavelength of 500nm through, which corresponds to OIII emission lines, and reducing the transmission of certain wavelengths of light
