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.
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.
Our filter set especially designed for astrophotography with CCD cameras, providing a natural color reproduction of planets, stars, emission- and reflection nebulas.
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.
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 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!
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.
