The MTV-73S85HP-EX-SW-R colour deep-sky Mintron was used at the prime focus of a Skywatcher 130P Synscan AZ GOTO telescope and DVD recordings were made of M13 and of dark-frames. The camera was set at 256 frame accumulation.
176 image frames were extracted from the DVD recording. A dark frame was made in Registax from 127 dark frames extracted from the DVD recording. Deep-Sky Stacker was used to derotate the images, dark-frame correct them, register and stack them. The resulting image was processed in The Gimp to improve the colour balance and levels.
