Astronomik has added a new range of RGB filters to its line of World class products. The new Deep-Sky RGB filters are designed for maximum deep sky imaging performance with CCD cameras.
Using Astronomik Deep-Sky RGB filters will benefit your imaging and will provide you with the highest-quality data for amazing images with unsurpassed sharpness, contrast and vivid colors.
The new Astronomik Deep-Sky RGB filters are the result of a long and detailed process of research and development. We have created the most advanced set of RGB filters for Deep-Sky imaging available today.
The transmission curves of the three filters are designed to give you strong and vivid colors with a strong reinforcement of the most important emission lines. Data taken with the new Astronomik Deep-Sky RGB filters is easier to process into a beautifull final masterpiece.
Feedback from our test-users and the first customers is really exciting. All of them reported smaller, sharper stars and this was one of our design goals, so these filters are designed to give you the best contrast and the smallest stars possible!
During the design of the Deep-Sky RGB filters we took a close look at the sensitivity curves of today’s popular CCD cameras. The result was we found a way to make one set of filters for all kind of sensors ranging from KAF- and KAI-sensors, to the chips made by Sony, meaning you can do 1:1:1 ratio RGB exposures with all sensors, with only minimal tweaking necessary during processing to achieve perfect colours in your image!
The transmission curve characteristics and coatings on the new Deep Sky RGB filters have been designed and engineered in such a way that no halos or reflections will be visible. Even with bright stars in the field of view you will be able to reveal the faintest structures in nebulas or galaxies
Additional to the Deep-Sky RGB filters Astronomik now offers you three different Luminance filters. The different spectral window of each new Luminance filters is designed to tune your setup to get the sharpest image from any optical design and any camera, even with instruments with less-than-perfect colour correction.

Like all Astronomik Filters, the new Deep-Sky RGB filters are made using an extremely durable and scratch resistant coating, deposited on the finest polished optical substrate, which is free of any striae or internal strains. All substrates are made to exactly the same thickness, so all of our filters are parfocal.

Astronomik now offers you a range of three different UV+IR blockers as Luminance filters. The different spectral window of each new Luminance filters is designed to tune your setup to get the sharpest image from any optical design and any camera.
The Luminance channel is probably the most important for a great final image! You want as much signal as possible so the filter should have the highest transmission possible with a wide spectral bandpass. This combination provides the greatest sensitivity and gives you the highest photon counts on your pixels. While the high transmission level is a great aspect of the new Astronomik Luminance filters, not all optical instruments or additional optical elements like correctors, field-flatteners or reducers, have perfect colour correction so it can be the width of the spectral band pass of the Luminance filter that can cause problems. A band pass that is too wide will allow the transmission of incompletely focused light (Chromatic aberration), making stars appear soft or bloated. In such cases image processing can become difficult, so having a slightly narrowed spectral window in your Luminance filter can reduce or eliminate this damaging effect.
To give you all the tools to gather the best data possible we have expanded our line of Luminace filters: Now you can select a Lumiance filter perfectly matched to the kind of telescope you use, to get the highest signal and sharpest image for the Luminance channel!
Depending on the color correction of your scope you may use a wider spectral window for the Luminance data. The L1 filter has the widest spectral window, the L2 is about the same as our current L-Filter and the L3 is much narrower.
If you use an optical system that is completely free of any chromatic aberration you should get an L1 filter for your setup. For general use the L2 filter is well suited to most optical systems with a corrector, flattener or reducer in the optical train while the L3 filter is designed for users of refractors with a less-than-perfect color correction and in combination with the new Deep-Sky RGB filters, the L3 filter will minimise the problem of bluish halos around stars.
The transmission curve characteristics and coatings on the new Luminance filters have been designed and engineered in such a way that no halos or reflections will be visible. Even with bright stars in the field of view you will be able to reveal the faintest structures in nebulas or galaxies.
Like all Astronomik Filters, the new Luminance filters are made using an extremely durable and scratch resistant coating, deposited on the finest polished optical substrate, which is free of any striae or internal strains. All substrates are made to exactly the same thickness, so all of our filters are parfocal.

After a long wait Astronomik have finally intruduced the Clip Filter Range for full format Canon DSLR Camera's.
If you are new to astrophotography and looking for your first filter: We do recommend the Astronomik CLS!
The CLS gives you maximum contrast due to it's effective surpression of artifical light pollution, but still gives you neutral and well balanced colors. With the Astronomik CLS you can do very deep images of amazing quality even from a urban/suburban observing site!
For the advanced Astrophotographer there is a selection of Narrow Band filters:
IR Pass filter designed for scopes of 8" Aperture or over.
The seeing can be calmer in longer wavelengths and some benefit can be gain by imaging in the IR or NIR.
The new series of Astronomik MFR Narrowband-Emissionline Filters is perfect matched to the requirements of astronomical Deep-Sky imaging. For the three most important emission lines of Oxygen (OIII), Hydrogen (H-alpha) and Sulfur (SII) you may select your filters eitherwith 12nm or 6nm Bandwidth (FWHM).
Our new filters are made in a completely new construction, which makes the best Out-of-Band blocking possible across the whole range of wavelengths from the UV up to IR! Your advantage of our new design is a extremly high contrast, minimized stray light, no halos and needle-sharp stars. With the new Astronomik MFR Narrowband-Emissionline filters you get data with the best quality possible: The best starting material to be processed to a awesome final image!
To get the maximum from the valuable observation time you need filters with the highest transmission possible. We do guarantee a transmission of 90%, but typically the transmission is as high as 96% . -These values are valid for the 12nm and the 6nm filters as well!
For maximum contrast the SII filter is carefully designed to block all light coming from H-alpha and NII (nitrogen).
Due to the new MFR coating the new Astronomik Narrowband filters can be used at nearly all instruments and safe you money:
Contrary to filters from other manufacturers the transmission curve of the new Astronomik Narrowband-Emissionline filters is nearly not shifted when used with fast optical systems! While other manufactures sell special "High Speed" filters or you even have to buy a new filter for each scope, this is not the case with the new Astronomik Narrowband-Emissionline filters with MFR coating. Save lot´s of money as you may use all filters with 12nm Bandwith (FWHM) with any instrument up to f/3 and all 6nm filters up to f/4!
Imaging with Narrowband-Emissionline Filters
If you have to observe from light polluted sites (like most of us...), imaging with Narrowband-Emissionline filters is the best way to take great images, as all kind of light pollution can be blocked very effective! Normaly an H-alpha filter should be your first step into this amazing field of astrophotography! With an Narrowband H-alpha filter you will be able to take deep and contrasty images even wih very heavy light pollution or with the full moon high up in the sky!
If you look at other astrophotos, an H-alpha is the best choice for all nebulas glowing red! An OIII filters expands your imaging possibilities, as you are able to image all greenish/blueish structures. Planetary nebulas and star forming regions are great targets! The SII filters completes your HSO-set of filters. With these three filters you are able to process your images like the ones from the Hubble space telescope!
The h-beta filter is not available in a 6nm version, as this filter has nearly no meaningfull application. To illustrate this, there are two images shown below: Both were taken with a unmodified Canon 650D. Even as the camera has a sensitivity of less than 10% at H-alpha, there is some signal und structure in the h-alpha image, while you cannot see anything on the image taken with an H-beta filter!
MFR Coating: The 12nm Filters can be used on all instruments up to f/3, the 6nm filters up to f/4. (Filters for faster optics are available upon request.)
High-Quality substrate: Astronomik filters are made with stress- and striae free, opticaly polished glass. The filter itself is made of ultra thin layers on this substrate!
Parfocal filters: All Astronomik Filters are parfokal! Due to the very small thickness-tolerance the focal plane is not shifted when changing filters! We have supplied parfocal filters for optical system as fast as f/1!
Coating: Astronomik filters are made of up to 130 layers which are coated on both sides of the substrate. These layers form the filter itself and act as a Anti-Reflection Coating.
Durability: Due to our coating technique all Astronomik filters are highly scratch resistant, not sensitive to moisture and do not degrade when getting older. -Every Astronomik filter will deliver it´s full perfomance and meet the specs at the point of shipping even after lot´s of years.
Integated Blocking: All unwanted light is blocked in the whole spectral range from UV up to the IR! (You will not need an additonal UV & IR-Blocker when imaging with the new Narrowband-Emissionline Filters with MFR coating!)
Wide range of available sizes from 1,25" up to square 50mm x 50mm filters.
Delivered in a high-quality Protection & storage box.
Due to our outstandding Coating technique we do offer a 10 year guarantee on all of our filters. (Check some forums, we REALLY do so!)
You get the highest quality possible with every single Astronomik filter to be able to take perfect images with your instruments! Especialy the filters against Lighpollution and the Narrowband-Emissionline filters will expand your imaging possibilities enormous! You are investing your money for an accessory which will work in lot´s of years in the same ways it did when it was brand new. Due to our special coating technique the filters do not degraed when getting older, and due to the new MFR coating you will be able to use the filter on nearly all instruments!
The Astronomik Type II filters have an integral IR-Blocking coating, thereby removing the need to have a separate permanently-mounted filter.
The standard set comprises R,G,B and a standard IR-Blocker. For full-spectrum imaging you can use a True Technology clear glass filter (no IR-Block) or an IR-Transmission filter, as this part of the spectrum is not blocked as would be the case with a permanently mounted IR-Blocker.
The Astronomik H-ß CCD filter is designed for CCD Imaging of gas nebulas with larger scopes. Due to the extreme small band pass of the H-ß line, the filter will produce a maximum increase of contrast even under best observing conditions. At faint H-II nebulas the Astronomik like the horsehead nebula the H-ß filter often makes the gain, that decides if the object can be seen or not. With the Astronomik H-ß you will be able to see the horsehead nebula with scopes of 10"...12" aperture under good skies.
The filter Clip series of filters are tailor made for Canon EOS DSLR and Astronimical Imaging.
Large filters for large camera lens objectives are very expensive If you place a filter holder between your camera body and lens you loose the ability to focus to infinity For very fast (low f/ number) telescopes like the Vixen R200SS or the Takahashi “Epsilon” astrograph. a filter drawer or a filter wheel cannot be used since the distance to the corrector lenses would be changed.
With long exposure times your camera’s sensor chip is exposed to more dust
With the Astronomik EOS Filter Clip System you can immediately take care of all of these problems!
The patented Astronomik EOS Filter Clip System is black anodized aluminum and laser-cut on state-of-the-art modern machines. It can be inserted within seconds directly into the EOS camera body. There are no changes necessary and all lens functions (focus, screen, image stabilization) remain functional!
Almost all Canon system lenses (with the exception of the EF-S series) and all M42 and T2 lens adapters, can be used with the Astronomik EOS Filter Clip System. The EOS Filter Clip System also acts as an outstanding dust shield, which prevents the possibility of dust settling on the sensor during long time exposure (The MC-Clear filter does not have a filter effect and only acts as a dust shield.)
The Astronomik CLS filter is a broadband light pollution filter for both visual and imaging applications.
Due to the design of the transmission curve the filter reduces the sky background and emission nebulae,planetary nebulae as well as open clusters, globular clusters and galaxies are all much improved visually as well as with a CCD camera.
The Astronomik CLS blocks the emission of Hg and Na streetlights as well as all Skyglow-lines
All major emission lines from deep-sky objects are passed without surpression.
Loss of transmission and colour displacements, that are prevalent in other light pollution filters, occur with the CLS filter only at extreme fast focal ratios of F2 or faster.
High transmission of nearly 100% between 450nm and 530nm
transmission of 96% at H-alpha
total blocking of all unwanted light from light-pollution
the ideal all round filter for deep-sky observing, even with small scopes
completly resistant against high humidity and scratches
highest optical quality on the market
