Visually they are very difficult objects to see both because they are faint and small. This 2 hour exposure was so faint that a single exposure of 5 mins realised a level of 25k verses 65k of the camera. The tail of IC 819 to the bottom of the image can be clearly seen, however the tail of the top image can just be seen. In the 3 hour exposure the 2nd tail can be clearly seen and the seeing that night was much better. I tried adding the 2 sets of data together but the final image was worse than the single 3 hours.
