NARROWBAND

(42 products)


We stock Antlia, Baader, Chroma, Optolong and ZWO narrowband filters for imaging with monochrome CMOS/CCD cameras.

Narrowband imaging filters are useful for isolating the various wavelengths produced by ionized gasses such as Hydrogen (H-alpha), doubly ionized Oxygen (OIII) and Sulphur (SII) in emission and planetary nebulae. By assigning the images captured through these filters with a monochrome camera to different colours, one can create stunning pictures reminiscent of those taken by the Hubble Space Telescope.
