Here's a reprocess from old data with the ED80. Now I have a bit more experience with narrowband processing I thought I'd give another go at the green Eta I did a while ago.

This time I used the Ha for sharpening only. The lum was made out of the 3 channels Sii, Ha & Oiii so there are more stars and they look a bit more natural. This one looks a bit better I reckon. Thanks for looking & let me know what you think.
I now added an LHaHaOiiiOiii version which I managed to squeeze more details out of. Full frame is at:
