The variety of uses for filters in amateur astronomy has considerably increased during the last decade, enabled by both more accurately manufactured optical accessories, and, above all, by the “digital revolution“.
The SkyTech CLS (City Light Suppression) filter is designed to improve the visibility of various deepsky objects by blocking light pollution, while allowing light from deepsky objects through.
The SkyTech LPRO-MAX filter is designed to improve the visibility of stars and deep-sky objects, by blocking light pollution, while transmitting light from deep-sky objects. It is therefore the best option for imaging in moderate light pollution where a more natural colour balance is desired.
SkyTech Tri-Band EOS Clip Filter for DSLR cameras (including astro-modified)Narrowband Bi-Colour imaging is a growing new trend in astrophotography, especially popular in light polluted areas, or for imaging in rural areas in moonlight.
Planoptically Polished with Phantom Coating Group (PCG). Drastically improves contrast for all reflector telescopes, without loss of brightness! Please ensure you order the size you require - Available in 1.25 inch (31.7mm) or 2 inch (50.8mm)
Tested in Germany under the stringent safety requirements of DIN EN ISO 12312-2 : 2015-11 and certified 100% safe for solar observation. Watch Solar Eclipses, Sun Spots, Planet Transits, crossing aircrafts and satellites.

An excellent & well made filter for observing our Moon. Like many astronomy filters, it is threaded and attaches to the underside of all popular 1.25 inch eyepieces (push-fit astronomy). This is the best seller for people when first buying an astronomy telescope.
Take beautiful images of deep-sky objects from light-polluted suburban locations with the Rowe-Ackermann Schmidt Astrograph (RASA) using this all-new light pollution suppression filter designed by Celestron and Astrodon, a leading astroimaging filter company.
This 1.25” Eyepiece & Filter Kit includes fourteen (14) accessories that will add new life to your telescope and your observing! You’ll get five quality Plossl eyepieces, a 2X Barlow Lens, six colored filters to improve observations of the planets, a Moon filter, and a foam-fitted aluminum carry case with extra room to grow.
Sky-Watcher's Moon Filter is an economical eyepiece filter for reducing the brightness of the moon and improving contrast.
This high performance CCD filter transmits only the Hydogen Beta emission line, and therefore is useful for greatly increasing the contrast of objects that glow in the corresponding region of the spectrum, for example the Horsehead, Cocoon and California nebulae.
The O-III narrowband filter is specially designed for the observation of gas and planetary nebulae.It distinguishes different contrasts of the wavelengths of light that pass through, giving ideal conditions for the observation of faint super nova remnants and planetary remnants.
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.
These contrast-enhancing anodized aluminium, optical glass filters are designed to block out the wavelengths of light emitted by mercury-vapour light and other common causes of light pollution, whilst providing higher transmission at critical hydrogen-alpha and hydrogen-beta lines than competing filters.
These high quality anodized aluminium, optical glass variable polarising filters reduce the amount of light entering your eyepiece.
This handy, time-saving device is a must-have for astronomers, for both visual and photographic use.
This long-pass filter limits transmission of light with wavelengths longer than 650nm.
This filter blocks night glow and airglow, sodium and mercury emissions (but not UV or IV).
This filter blocks low and high pressure mercury and sodium vapour lamplight and neon light whilst letting the rest of the visible spectrum through. Excellent for viewing all deep sky objects under the urban sky. Suitable for visual observations and for CCD photography.
With the help of this special CE certified film with a filter factor of 100,000 you can observe the sun directly with your binoculars or telescope
