With the Hydrogen-Beta line of the spectrum isolated, the Astronomik 12nm H-Beta filter can detect faint nebulae like the Horsehead, the Cocoon, or the California.

The Astronomik CLS Filter is considered the highest quality light pollution filter on the market today.

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.

Great for planetary nebulae and supernova remnants.

The 6nm narrow bandpass H-alpha filter has a transmission of 85% - 90%.

The Astronomik CCD IR Blocking Filter blocks IR radiation when used in front of the CCD, thereby removing glare caused by infrared radiation from the image.

The Astronomik LRGB Type 2c Filter Set includes a Red, Green, Blue, and L (UV & IR-Cutoff) Filter, each mounted in 1.25" (31.8mm) cells.

The Astronomik Luminance (IR/UV Blocking) Filter is optimized for systems with focal ratios between f/0.5 and f/50.

The Astronomik Mulit-Coated (MC) Clear Filter should be used if the focal plane of your imaging system should stay in the same place as with other Astronomik filters in place.
