A monochrome camera is ideal for imaging in H-alpha light, which is monochromatic light at 656.28 nm. A monochrome camera has higher spatial resolution than a colour camera. The colour is added at the end of the process for cosmetic purposes to represent the wavelength of light used for the capturing. This camera has a 1/2" monochrome 1.3 mega-pixel CMOS sensor which is large enough for the whole of the solar disk to fall on the sensor. This makes the camera suitable for whole disk imaging.
