The image is a 4.5-hour RGB exposure using a Tele Vue NP127is telescope and a QSI583wsg CCD camera on a CGE PRO mount. I took the image from Calgary, Alberta. Camera control and preprocessing was done through ImagesPlus. Processing was done through PixInsight with final touch-up, as required, through Photoshop. Guiding was through PHD2 and a Lodestar camera. What I like about this image and all globular clusters is the intensity of such a large number of stars all within such a small area.
