Astronomik and Gerd Neumann Filters
Astronomik filters are a valuable complement to your telescope optical equipment train. They are used worldwide by professionals and advanced amateurs because of their superior quality.
The Astronomik CLS blocks the light of the spectral lines of mercury and sodium-vapor lamps and lets the largest part of the visible light and H-alpha emissions pass.
The filter enhances the contrast between all deep-sky objects and the background.
You will enjoy using your Astronomik UHC filter because you will see more stars and more details in deep-sky-objects compared to using filters from all other manufacturers.
The UHC-E filter is for deep-sky observation of emission nebulae and comets under light polluted skies, particularly suitable for small ’scopes.
This H-alpha Filter is suitable for imaging of Hydrogen nebulas from observation sites with light pollution and from dark sites as well.
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!
This Astronomik OIII-CCD Filter is suitable for imaging of OIII nebulas from observation sites with light pollution and from dark sites as well.
From the start, the Astronomik OIII filter has been very specifically designed for the visual observation of gaseous and planetary nebulae.
The Astronomik H-beta is a filter for visual observation, in particular with instruments of larger aperture.
The new Deep-Sky RGB filters are designed for maximum deep sky imaging performance with CCD cameras.
Our filter set especially designed for astrophotography with CCD cameras, providing a natural color reproduction of planets, stars, emission- and reflection nebulas.
Put this filter in front of your camera and you will get rid of all problems caused by IR like bright halos around all objects and a very soft overall image.
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 Astronomik ProPlanet 642 BP is the latest addition to the family of Astronomik ProPlanet IR-pass filters.
Ideal filters for the reception of the moon and planets, notably Mars, with telescopes from 6" (150mm) aperture.
The effects of seeing are distinctly reduced. It is your entry into previously unknown dimensions of photography of the moon and the planets.
This Multicoated (MC) glass serves as dust protector or to keep your system parfocal with other Astronomik filters.
Enables converted DSLR cameras (without inbuilt IR-filter) in order to be used for 'terrestrial' photography.
Using this filter, you may use much longer exposure times to capture faint moons, rings or ring fragments as they do reflect sunlight and have no absorption band.
A dark filter making the aquisition of dark-calibration frames a breeze!
The Aurora Flatfield Panel is a new light source technology for taking flat field images for use in calibration with digital images.
Use your Astronomik EOS Clip-Filter with all your eyepieces or even with a cooled CCD camera!
Astronomik Filters for Astronomy
Superior Substrate: Astronomik filters consist of a precision polished substrate on which the actual filter, in the form of very thin (dichroic) interference layers, is applied. Because of these high quality measures Astronomik filters will in no way reduce the performance of your optical system. And contrary to common experience with other manufacturers´ filters, with Astronomik filters stars remain fine needle points of light!
Coating: Astronomik filters consist of up to 130 layers deposited on top of the completely transparent carrier glass. These layers work as the actual filter and as an antireflective coating.
Durability: Astronomik filters are completely scratch resistant, and not sensitive to moisture, dew, or high humidity. With others’ filters, after a few years, you start to notice their filter is no longer up to its full capability. Not so with Astronomik filters which maintain their ‘brand new’ transmission specifications year after year.
Parfocal Filters: All Astronomik CCD Filters are parfocal. When changing filters, the focal point will not change; you will not have to refocus your camera. This is due to the high tolerance and very low thickness of the substrate and coating.
Comparing Astronomik CCD Photographic Filters to our Visual Filters: Unlike Astronomik Visual Filters which do not require IR blocking, our Astronomik CCD Photographic Filters do include IR blocking filter layers to prevent any problems from Infrared Radiation (IR) when using CCD and chemical photographic devices.
Astronomik filters come with a 10 years warranty.
Please note, the "unmounted" filters do have a black retaining ring, the protective ring and blackened filter edges prevents stray light, the filters are mechanically protected and easier to handle.
