I tried to photograph the Moon in three ranges – infrared (850 nm), green (550 nm) and ultraviolet (350 nm). Then I combined a color image from these three shots. Some difficulties arose due to a slight rotation of the camera during rotation of the filter wheel. In addition, with such a wide range, lateral chromatic aberration became more noticeable. To be honest, I expected a more contrasting result – the image is similar to RGB, but with a slightly different color scheme. However, after adding contrast to Image Analyzer, an interesting result was obtained.
