Sorry for poking you, Ken, partly tongue in cheek
The incredibly dim R4 jet in NGC 1097 I got to a SNR of just over 9 and convinced myself and a few others that it was visible.
I have a half completed image of IC5148 that I really should finish up. It has a very faint Oiii halo that I have at a SNR of around 14 after 46 hours of 1800s subs. It's quite visible but not pretty.
SNR>20 sounds quite luxurious
