Astronomik LRGB H-alpha SII OII Ultimate CCD Filter Set

The L-RGB filter set divides the spectrum into its components red, green, blue and luminance. This color separation can be achieved with pure b/w CCD sensors. The separation corresponds to the color sensitivity of the human eye. With Astronomik L-RGB filters you will create an ideal raw image for processing in the sRGB color space.

Imaging with Narrowband-Emission line filters is one of the best ways to take great images, most light pollution will be blocked. With a Narrowband filter, you will be able to take deep and over contrast images even with very heavy light pollution or with the full moon up! H-alpha is best for all nebulas with a lot of red. OIII filter will expand your imaging possibilities, as you are able to capture greenish/blueish structures. The SII filters complete your HSO-set of filters to where you are able to process your images like the ones from the Hubble space telescope!

Due to the high-precision machining of the carrier substrate, Astronomik filters are parfocal with wedge errors below all usual margins while of course being diffraction limited. Issues concerning focal distances as well as the exact location of the images of each color image are not a problem at all!
