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.
AstroSolar Photo Film (imaging only), telescope quality, Optical Density OD = 3.8; Digital solar imaging at highest magnifications and short exposure times. Not suitable for visual observation; This highest precision film consistently produces strehl ratios of 94 to 96 percent at interferometric tests – thus it performs optically; like a Fluorite Triplet Lens by Carl Zeiss or Astro Physics; AstroSolar Photo Film OD 3.8 is only intended to be used by well-experienced Astro-imagers. This material is not intended to serve; for protection during visual solar observation.
When using AstroSolar® Safety Film 5.0 – mounted in front of your optics – you can image the Sun and safely look through the viewfinder of your camera – or you can directly look into the Sun with telescopes and binoculars at any suitable magnification. The coating of AstroSolar® Safety Film 5.0 is subject to constant quality control. Its reflective property and security for solar observation through optical instruments is being tested repeatedly. AstroSolar® Safety Film 5.0 reduces the intensity of solar radiation by 99,999% to a factor of 1 : 100 000 of the initial value. Multiple coating processes on both sides of the carrier film are adding up during production to result in a perfectly uniform filtering result and help in neutralizing the effect of microscopic pores in the coating hat plague conventional glass solar filters which are commonly only coated on one side of the glass.
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 M27 are 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.

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!
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.

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.
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.
The 1.25" moon filter, consisting of flat steamed glass, is simply screwed into the eyepiece thread. It reduces the brightness of the moon and thus enhances the contrast in the observation. This filter is mainly necessary during the major moon phases since the subjective glare of the moon then is strongest and can quickly become unpleasant.However, the filter doesn't only offer advantages during lunar observation, but it also allows for high contrast observations of planets. It amplifies the surface details that make observation particularly interesting. The filter is most strong in the red/blue range. Thus, objects such as the 'Great Red Spot' and the bands of cloud on Jupiter appear clearer.A particularly disruptive factor during observation is the illumination of street lights. This is blocked in the conventional spectral range so that high-contrast observations are possible. This premium moon filter is much higher quality than similar products: There are some cheap offers in this field where the image quality of the telescope suffers due to the filter. This premium moon filter, however, is characterized by very good characteristics
Omegon pro H-beta 25nm filter - the best way to see the Horsehead nebulaThere are objects that are so interesting that you should get round to observing them at least once. This includes the famous Horsehead Nebula, which adorns so many wonderful astronomy images. But what would it be like to see it 'live' with your own eyes?With the Omegon Pro H-beta filter and a telescope above 8"-10" in aperture, your wish can come true. The filter allows light to pass only in the hydrogen emission region at 486nm. With a bandpass of 25nm, it is particularly suitable for visual observing.The filter will do all of the following:improve contrast between the object and the night sky background;provide a particularly good image under a dark sky;be particularly useful for observing the Horsehead nebula, Cocoon nebula, and California nebula.The H-beta filter offers you something more than just the 'everyday sky'; it lets you explore the extraordinary!Omegon pro filter with its own test certificateYou benefit from the fact that each Omegon pro nebula filter has been fully tested by us and comes with its own test certificate. This certificate is proof of the quality of your filter.
The Celestron 1.25” Star Diagonal slides into the focuser (1.25”) of your refractor or catadioptric telescope and accepts standard 1.25” eyepieces, allowing you to view objects more comfortably. A diagonal that is angled at 90º helps avoid neck strain when looking through the eyepiece.Please note that a 90º diagonal will display images that are right side up, but left to right orientation will be reversed.
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.
This contrast-enhancing anodized aluminum, optical glass filter is designed to block out the wavelengths of light emitted by mercury-vapor light and other common causes of light pollution, whilst providing higher transmission at critical hydrogen-alpha and hydrogen-beta lines than competing filters. Bright, light-polluted skies appear much darker, and the contrast between object and sky is improved significantly. This contrast-enhancement effect is particularly apparent on nebulae. Unlike stars, emission nebulae give off the light in a very narrow range of wavelengths. This filter allows maximum transmission of the important wavelengths of H-alpha, H-beta and doubly ionized oxygen – the ones most commonly emitted by nebulae. Views of galaxies and star clusters are also enhanced but to a lesser degree. Also improves contrast on reddish planetary detail. Works well in telescopes of all apertures but is highly recommended for use on smaller telescopes up to 114mm diameter, where conventional filters swallow up too much light. Supplied with storage case.
