Astronomik CLS Filters

$109.00$289.00 AUD

The Astronomik CLS is a budget filter for visual observation, Black & White photography and CCD photographs of nebulae, galaxies and star clusters with astronomical instruments of any size.

It blocks the light of mercury and sodium-vapor lamp spectral lines (street lights), while letting the largest part of visible light and H-alpha emissions pass. All the important emission lines, as well as the spectral region that the very well dark adapted eye can see, pass through the filter unhindered.
