UPDATE:
I was able to grab another 2 hours of data (as well as proper Flat/DarkFlat calibration frames) last Thursday night. So I now have a total of 4 hours on this one.
I can see more detail in the bubble's tendrils of gas now, and I processed it slightly differently to try and increase the contrast between the bubble and it's background / surroundings.
I also found out that it has appeared as NASA's APOD back in June 1998! See

Again - I'd love to see what a longer FL scope will produce.
Cheers,
V.
