These filters each blocks out different colors, thereby allowing for the watcher to see the objects in more details and contrast. Compatible with all telescopes and useful for astrophotography. FILTERS: #21 Orange - The orange filter blocks blue and green wavelengths, thus enhancing details in Saturn's and Jupiter's cloud belts. On Mars, it sharpens boundaries between orange and greenish areas. #25 Red -The red filter blocks blue and green light nearly in total, which means you get a very strong contrast, for instance, between bluish toned structures and the brighter details on Jupiter's and Saturn's clouded surface. However, this filter is mainly used to observe Martian polar caps.#82A Light blue - The light blue filter is suitable for Moon, Mars, Jupiter and Saturn observation. It improves contrast on faint areas without affecting the planet's brightness, which is why this filter is often used in combination with others.#12 Yellow - The yellow filter improves contrast on Moon craters; on Mars, channels and polar caps become more apparent. On Jupiter and Saturn, contrast is enhanced on the bluish ammonia cloud belts.#56 Light green - The light green filter is ideal for observing the ice caps on Mars and the yellowish sandstorms on the Martian surface. It also improves the contrast of reddish and bluish structures in Jupiter's atmosphere.#47 Violet - The violet filter totally blocks red, yellow and green light, which is useful when observing the polar regions on Mars. With larger telescopes (>12"), it also allows distinguishing some structures in Venus' atmosphere.
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. This filter permits superb views of objects like the Orion, Lagoon, Swan and other extended nebulae. It performs well in smaller aperture instruments owing to its greater light transmission than the O-III, yet still suppresses light pollution well. The UHC filter is the best all-around dark-sky nebula filter. Supplied with storage case.

Even after the sun eclipse sun observations are of great enjoyment. The sunspots are constantly changing their size, shape and position. Depending on the magnification used even the Umbra and Penumbra, center and edges of the sunspots are visible. It is, however, of essential importance for the protection of your eyes to reduce the sunlight to less than 1/100,000 of its normal brightness. The Astro Solar Sun Filter Foil provides these conditions. It needs simply to be mounted on the front opening of the telescope tube. The Astro Solar Sun Filter Foil meets highest quality requirements and is therefore comparable to expensive plan parallel glass filters. The foil production is under permanent and strict quality control. The multi-reflective foil guarantees an extraordinary even filter effect, so that just one layer of the foil will be sufficient for sun observations.
These high-quality anodized aluminum, optical glass variable polarising filters reduce the amount of light entering your eyepiece. You can progressively dim the view when observing a bright object, such as the Moon or certain planets, to a level according to your needs, whilst increasing contrast, reducing glare and increasing the amount of detail that can be studied. The light transmission can be varied from 40% down to as little as 1%. The filter will not change the color of the object being viewed and will prevent eye fatigue and loss of night vision. Each filter set consists of two polarizing filters, one which can be rotated in its cell to adjust the brightness. The filters, used as single elements, can also be used for daytime terrestrial use for reducing sunlight glare from lakes oceans or window glass. Available in two sizes, threaded to fit either standard 1.25” or 2” astronomical eyepieces. Supplied with storage case.
Omegon 1.25" Skylum filter - the easy way to discover more on Mars and Jupiter Would you like more detail and contrast when observing the Moon and planets? And that the object should still look natural? - then the Omegon Skylum filter is the 'star' in your eyepiece. It amplifies details in the red or blue parts of the spectrum - see the bands on Jupiter more vividly and make out more detail on Mars. The advantages in a nutshell stronger contrast with Jupiter and Mars - see how the red details stand out deep sky objects - improved contrast with nebulae and galaxies ideal for small telescopes - the image in the eyepiece is still bright and clear 1.25" filter with filter thread also suitable for astrophotography An 'expert' for the entire night sky You do not need to spend time considering which filter might be useful for your object. The Skylum filter is universal and is suitable for many astronomical objects. It turns the night sky background slightly darker and highlights blue and red colours. It will produce more vivid details, even in reddish nebulae. One has to say - it has a real 'sky glow' effect. The filter increases contrast, but causes little attenuation. It is useful for observing the crescent phases of the Moon. It prevents blooming when observing bright planets. And what are the advantages for you? - in future, you will be able to observe these objects in even more detail. Nullifies artificial light Similar to a nebula filter, the Skylum filter only allows certain wavelengths to pass through, and reduces scattered light. In addition, it blocks the light of many street lamps - for example the spectral lines from sodium vapour lamps. The light of the astronomical objects is therefore seen more intensely by the eye. For small and large telescopes The Skylum filter has high light transmission. This makes it ideal for visual observing with small or large telescopes. It will do a good job even with an 80mm telescope. The 'nice' filter for star clusters and galaxies Do the stars looking like glittering diamonds on black velvet? That would be nice. But from the city, the sky sometimes looks like a grey concrete wall. Bur you do not have to put up with this - put the Skylum filter into your eyepiece and to start enjoying star clusters and galaxies. Already the sky looks much darker and the objects clearly more beautiful. Make more of your observing!
One of the most important obstacles for the exploration of the night sky is the brightening of the night sky by artificial lights, such as streetlights. The night sky is not really dark in the vicinity of towns or cities, which reduces the visibility of objects bejond the solar systems enourmously. Depending on the type of the celestial object it is possible to increase the contrast dramatically by blocking the annoying artifical light. The EXPLORE SCIENTIFIC UHC filter uses a characteristic property of the so called emmission nebulae. Those objects glow in special colors, the so called emmission lines. Those emmission lines are linked to chemical elements - in this case hydrogen at 486nm and 656nm, plus oxygen at 496nm and 501nm. The EXPLORE SCIENTIFIC UHC nebula filter blocks all other colors (and thereby nearly all of the artificial light) and only the emmission line of the hydrogen and oxygen can pass the filter. The result is astonishing: suddenly nebulae are visible at locations that were completely empty without filters. In suburbian skies for example the Owl-nebula M97, the Veil-nebula Ngc 6992 or even the bright Dumbell-nebula M27are not clearly visible. By using this filter you can see the nebulae and their structures without problems. A must for every visual observer. The Explore Scientific nebula filters come with a individual test certificate - your guarantee to receive a premium filter.

The ULTIMATE nebula filter. The original Lumicon Ultra High Contrast Filter is unbeatable for revealing nebulosity. This achievement in filter performance is attributed to exclusively designed coatings that isolate the two doubly ionized oxygen lines (496 and 501nm) and the H-beta line (486nm) emitted by planetary and most emission nebulae. The result is superb views of the Orion, Lagoon, Swan and other extended nebulae. Useful to great advantage under dark skies.
The Lumicon Comet Filter, a narrow bandpass system (25nm), isolates the 501nm OIII line and both Cyanogen lines at 511nm and 514nm. The high contrast gain of the filter reveals the delicate ionized tail of gaseous comets, allowing you to see their full extent. The Comet Filter also helps you to better distinguish gaseous comets from dusty comets which normally show little contrast gain. Howard Brewington, a famed comet discoverer, says: "I discovered Comet Aarseth-Brewington, 1989a1, using the Lumicon Comet Filter. The filter doubled the contrast, making the comet very easy to spot." Why make comet-hunting harder than it needs to be?

The LF2090, 2" Neutral Density 50 Filter (ND50), transmits 50% of all incident light while blocking 50%. For lunar and planetary observing, and splitting double stars. Lumicon Neutral Density Filters are made from renowned Schott and Hoya optical glass and allow for maximum contrast on viewing planetary and lunar detail. Individually precision ground highly polished with maximum light transmission coatings on both sides. For 1.25 eyepieces.
Lumicon Polarizing Filters are manufactured from optically flat Hoya polarized glass. They are the best for cutting all glare and increases contrast on bright celestial objects such as the moon at full illumination and can be double-stacked with other Lumicon filters for use on bright planets. They are also useful for daylight observation of land, sea, and nature. In addition to polarizing the light, they reduce its intensity by a factor of about 3 times.
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, the contrast will be improved and more detail will be seen. Observers often ask which filter should be used for which planet, and for this question, there are no firm answers. For one thing, the colors of the details on some planets are continually changing. Also, everyone's eye response is slightly different, we're talking about very subtle detail, and the best results have to be achieved by trial and error. And since the filters can be stacked by threading them together, there are a lot of combinations to try. Antares filters are available singly and inset in the most popular hues for both 1.25" barrels.The Lumicon Lunar & Planetary Filter Set, LF5045, is an excellent "starter-kit," a set of four (4) of Lumicon's most popular 1.25" lunar and planetary filters: the LF1025, #15 Yellow-Orange; the LF1060, #56 Green; the LF1070, #80A, Blue; and the LF1085, Neutral Density 25.

The 82° Series eyepieces come with a twist-up rubber eye-guard that raise to the desired height for the comfort of the observer, and as experienced astronomers know, eye comfort is critical when trying to observe at the visual limits of the telescope. To keep internal reflections to a minimum, all internal surfaces of the eyepiece barrel are flat black, as well as the edges of the lenses themselves to minimize the scattering of light within the lenses themselves. All 82° Series eyepieces are fully multi-coated and edge-blackened to produce maximum contrast.
