The downside of imaging with a full moon even with narrowband is that you don't get the contrast you want or need and with my local light pollution levels it just makes it worse. The image showed a lot of promise but trying to get the best out of the data was hard and I pushed the data way too far. But you only learn from your mistakes... Definitely a target that I will revisit at some point though.
