The second target for Saturday night was Mu Cepheus and IC1396 again. I’ve looked at this one recently but with the 10 minute sub-frames I was getting I wanted to see if there was any more detail possible. Nine 10 minute frames were stacked and then processed in Photoshop. The biggest problem area is around the Garnet star itself and there’s a dark ring I haven’t managed to eliminate yet. The problem is caused by the high difference in brightness between the star and nebula and I need to research some techniques for reducing this artifact.
Comparing this image with the previous one, there’s more subtle detail in the dark nebulae.
