This is a complex of emission reflection dark and planetary nebulae. Overall it is quite dim and a challenge for a DSLR.
It was difficult for me to process as although David did a great job in capturing more than 3 hours of data the final stacked image was still quite dim. I have worked on the image for many hours and decided to post as is. I would like to start again from scratch sometime and see if I can improve it.
