Description

An unusual spiral galaxy with a central bar, prominent blue ring, and long faint outer arms. A large grand design spiral galaxy in the background adds to the composition of the image.

Captured with a monochrome camera and L,R,G,B filters. The final image incorporates a total of 29 hours of exposure time spread over six nights. Seeing was not great most of the time. Struggled with finding guide stars with the off-axis guider.
Overall pretty happy with the final result.
