With traditional monochrome RGB imaging you have about three minutes to take videos for all three colours, which just gives time for one red image (left); the WinJupos Image Derotate facility increases that time period. The combined image on the right was made from four red videos captured over a 15-minute period and gives a much smoother and more detailed result. Credit: Martin Lewis
