Thanks Nik! I definitely think that there is more to be seen hidden in the background with some significant integration time investment.

The image is nice but no more so than others that have posted with lesser total integration. Sorry but that is my opinion for what its worth  |
True... but I'm not chasing more detail in the core, that can be had after just a few hours, I'm really chasing the background detail; the
really faint extra shell(s) around the outside, and the 58hrs of Ha in my image is (I suspect) only scratching the surface of what's needed to really show their full extent.
See the attachment for an inverted copy of the Ha Channel to see what I mean.
