Yep, looks very deep, Fred. I have about 12 hours of Ha from last year (and 9 hours each of OIII and SII.) You've definitely got some faint stuff in the Ha that I didn't catch. Well done!
I struggled to get colours I liked with this object when I tried to process it last year. Since then I've learned a bunch of new tricks and built a handy PI colour masking script so I reckon I might be able to do it justice now. Must put it back in my processing queue
Cheers,
Rick.
