DSI Pro II behind a 6" f1.8 homebuilt astrograph
After taking many images of 15 sec or less over the course of the evening I realized that because of the reasonably large field of view I need not be too concerned about the relative motion between the object and the background stars. This image consists of H-alpha, green and blue data all with 1 min integration times taken in quick succession. The nucleus was taken at 1 sec and layered in with Photoshop.
