The image is a 3-hour narrowband 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 find interesting about the image is the level of detail in the wall combined with the wispy clouds of dark nebulosity.
