The field of use ranges from focal ratios of 1:3 to 1:15 for telescopes up to 5'' (125mm) in aperture. The scope of use for the filter is the observation of gas nebulae and planetary nebulae in cities and light-polluted environments.\u003cbr\u003e \u003cbr\u003e \u003cb\u003eEffectiveness\u003c\/b\u003e\u003cbr\u003e \u003cbr\u003e The filter blocks the emission lines of low and high-pressure lamps (mercury (Hg) and sodium (Na)) and airglow lines. As a result, you get an \u003cb\u003eincrease in contrast\u003c\/b\u003e between the sky background and the object being observed. Due to the wide full-width at half-maximum, the contrast is lower compared to the UHC filter, but the greater amount of light allows for profitable use even with small telescopes.

properties of the L-RGB Type 2c filters are optimized for CCD astrophotography. The set allows for color-accurate imaging for all types of objects. While other brands make strange compromises, we offer the best color reproduction possible. Both stars and objects that emit only at specific spectral lines are reproduced in their true colors. You get CCD images with perfect colors, as if the objects were bright enough to be seen with photopic vision. This feature is the main difference between Astronomik filters and those from other manufacturers.\u003cbr data-mce-fragment=\"1\"\u003e \u003cbr data-mce-fragment=\"1\"\u003e The following aspects were very important for the design of our filter set:\u003cbr data-mce-fragment=\"1\"\u003e \u003cbr data-mce-fragment=\"1\"\u003e - simple image processing for the user\u003cbr data-mce-fragment=\"1\"\u003e \u003cbr data-mce-fragment=\"1\"\u003e - maximum transmission (nearly 100%) for short exposure times\u003cbr data-mce-fragment=\"1\"\u003e \u003cbr data-mce-fragment=\"1\"\u003e - adjusted transmission of individual filters for optimal color reproduction\u003cbr data-mce-fragment=\"1\"\u003e \u003cbr data-mce-fragment=\"1\"\u003e - use of industry standards\u003cbr data-mce-fragment=\"1\"\u003e \u003cbr data-mce-fragment=\"1\"\u003e Astronomik does not stop thinking at the moment the photo is taken. Even more importantly, astrophotographers should be given a tool that offers a simple and elegant editing process. To maintain color accuracy, we calculated our filter set for the sRGB color space, which is used as the industry standard by most monitor, printer, and imaging software manufacturers. As a user, you do not need to spend time learning colorimetry and color spaces. We have solved the specific problems of astrophotography for you.\u003cbr data-mce-fragment=\"1\"\u003e \u003cbr data-mce-fragment=\"1\"\u003e Thanks to high-precision manufacturing of the carrier substrate, our filters are parfocal with wedge errors below all standard margins. In order not to be a bottleneck in a high-quality optical system, Astronomik filters are naturally diffraction-limited. Issues regarding focal lengths and the exact position of the images for each color channel are not a problem at all!\u003c\/p\u003e Primary use \u003cp data-mce-fragment=\"1\"\u003eThe L-RGB filter set divides the spectrum into its red, green, blue, and luminance components. Therefore, color separation can be achieved with pure black and white CCD sensors. The separation corresponds to the color sensitivity of the human eye according to DIN 5032. By using the sRGB color space, it is possible to maintain the image color throughout the entire image processing and output workflow. With an Astronomik L-RGB filter set and your camera, you create the ideal raw material for processing images in the sRGB color space.\u003c\/p\u003e Other uses \u003cul data-mce-fragment=\"1\" type=\"disc\"\u003e \u003cli data-mce-fragment=\"1\"\u003e \u003cp data-mce-fragment=\"1\"\u003eIn combination with Astronomik line filters, your images will show interesting details of astronomical objects.

The contrast gain is much higher due to the smaller FWHM. The 6nm H-alpha filter is the right choice for extremely faint objects, even in the Milky Way, and for observations from heavily light-polluted locations. The Astronomik 6nm H-alpha CCD completely suppresses emission lines from artificial lighting (mercury (Hg) and sodium (Na)) and skyglow. Transmission losses and chromatic distortions, which occur with other filters, only occur with Astronomik filters when extremely bright aperture ratios come into play.

Normally, an H-alpha filter should be your first step into this fantastic field of astrophotography! With a narrow-band H-alpha filter, you will be able to take deep and contrasty images even in conditions of very intense light pollution or with a full moon high in the sky!\u003cbr\u003e If you look at other astrophotos, an H-alpha is the best choice for all nebulae that glow in red! An OIII filter expands your imaging possibilities, as you can visualize all the greenish\/bluish structures. Planetary nebulae and star-forming regions are great targets! The SII filters complete your HSO filter set. With these three filters, you will be able to process your images like those of the Hubble Space Telescope!\u003cbr\u003e The H-beta filter is not available in the 6 nm version, as this filter has almost no significant application. To illustrate this, there are two images shown below: Both were taken with an unmodified Canon 650D.

This filter should be used on telescopes with a diameter of 8\" (20 cm) or larger. Smaller instruments do not gather enough light for meaningful and satisfying astronomical work.

to the ProPlanet IR 742 for use with converted DSLR cameras, CCD cameras, and webcams. The effects of seeing are sharply reduced. It is your entry into previously unknown dimensions of lunar and planetary photography.\u003cbr\u003e \u003cbr\u003e The ProPlanet IR 807 lets only infrared light with wavelengths above 807 nm pass through. In this wavelength range, the effects of seeing are significantly lower than in the visible spectrum of the human eye. This allows for much sharper images than those usually obtained by the device and location. Another advantage is that the sky background is dark at advanced twilight, allowing for photography of planets and the moon even in daylight.\u003c\/p\u003e Main use \u003cp style=\"border: none; padding: 0in\"\u003eThe Astronomik ProPlanet IR 807 cuts off the visible part of the spectrum and lets light with wavelengths above 807 nm pass through.

planets with webcams\u003cbr\u003e \u003cbr\u003e This filter has been designed to block IR rays. This filter is ideal for cameras that do not have specific UV sensitivity. This primarily concerns webcams, industrial cameras (Mintron, DMK without IR filter), and the Meade LPI or DSI.\u003cbr\u003e \u003cbr\u003e With an \u003cb\u003eIR block, you prevent blurred ghost images\u003c\/b\u003e. Since optical systems with at least one lens are generally corrected only for the visible spectrum, different focal points are generated for visible light and infrared light, which leads to blurred ghost images in addition to the actual image. Most webcams are also sensitive to IR, so a block is needed to hide the out-of-focus image.\u003cbr\u003e \u003cbr\u003e \u003cb\u003eFunction\u003c\/b\u003e\u003cbr\u003e \u003cbr\u003e The function of blocking filters is to adapt cameras that lack an internal filter to the spectral sensitivity of the eye. This is a necessary measure because almost all lens-based optical systems are corrected for the 400 to 700nm region to accommodate human vision. Depending on the manufacturer, cameras have sensitivity between 380 and 1000nm, thus also making visible the regions not corrected in lens systems. The IR filter also offers \u003cb\u003eprotection against dust and particles\u003c\/b\u003e - like MC clear glass - without cutting the visible spectrum in any way.\u003cbr\u003e \u003cbr\u003e
