Our own society secretary, Darren Swindells took this image of the notoriously difficult to see Barnard 33, otherwise known as the Horsehead Nebula in the constellation of Orion. The reflection nebula NGC 2023 can also be clearly seen at the bottom of the image just off centre. After Darren added the luminance data to the RGB data, the contrast of the image increased massively and the features of this famous nebula really came through. More please!
